App roundup: 4 apps to take with you on your next vacation

Brittany K — Fri, 24 May 2013 18:00:00 GMT

Hi, it’s Brittany K again. Last time, I talked about some of the apps I use to plan a trip. And since I got back from a trip to Washington, D.C. a few weeks ago, this time I thought I’d tell you about some of the apps that came in handy while I was traveling.

FlightAware

For me, the downside of traveling is all the waiting – especially at the airport, where it seems like I’m always either standing in line, or killing time until I have to stand in line again. So I’m a big fan of FlightAware: you type in your flight info, and then FlightAware tracks your flight and sends you an alert if there are delays, so you can plan accordingly. You can also get info about the type of plane you’ll be flying on and the airports you’ll be leaving from and going to. And once you’re in the air, you can use FlightAware to see if your flight is going to arrive on time.

Netflix

Even waiting has its upsides though. For one thing, I always have plenty of time to catch up on my Netflix queue, especially now that a lot of airlines have in-flight Wi-Fi. If you subscribe to Netflix’s streaming service, you can use this app to watch any of the movies and TV shows in your instant queue whenever you’re connected to the Internet. And if you have the Netflix app installed on more than one device, you can start watching something on one and pick up where you left off on the other. I started watching a movie on my phone in the airport, then switched to my tablet when I got on the plane – all without losing my spot.

Destination Manager

On my trip to Washington, D.C., finding the major tourist attractions wasn’t a problem (things like the Capitol and the Washington Monument are kind of hard to miss). But finding the nearest ATM, coffee shop, or subway station can be a bit more of a challenge. I ended up using Destination Manager a lot to find places - you can browse the app’s list of categories for the type of place you’re looking for (like a restaurant, drug store, or train station), see all of the options nearby, and read reviews from other travelers. Or you can use the map view to just see what’s closest. Once you’ve picked a place, you can get directions from your current location. And there’s a pretty wide range of places listed in the app; so far, I haven’t needed to find the nearest hospital, police station, or lawyer on any of my trips, but it’s good to be prepared, right?

StreetEats

My coworker, Tatsuo, already mentioned this food truck app in a previous post, but it’s worth bringing it up again because this turned out to be a great way to find non-touristy, quick food. While I was in DC, I used StreetEats to check for food trucks near my hotel and ended up at Dangerously Delicious Pies (where potatoes au gratin became one of my new favorite pie fillings).

I’m never quite sure what’s going to come up when I’m traveling, so it’s good to know I have a few apps I can pull out to help me pass the time or find what I need in an unfamiliar place. If you’re heading out of town soon, give these apps a try. And be sure to let me know if there are any great ones out there that I’m missing. Bye for now!

Note: Some apps and services might not be available in all countries or regions.

The cornerstone app architecture for Windows Phone development is the MVVM (Model-View-ViewModel) design pattern. In this video, Matthias Shapiro demonstrates the basic structure of a Windows Phone MVVM app. He shows how you can build robust and flexible MVVM apps for the phone that take advantage of data binding, commanding, and presentation logic (ViewModel) portability.

Windows Phone 8 XAML LongListSelector

Adam Denning — Thu, 23 May 2013 19:47:00 GMT

This blog post was authored by Rohan Thakkar, a Program Manager on the Windows Phone team.

Last year we evangelized the use of the LongListSelector control to provide smooth infinite scrolling scenarios. The LongListSelector control is so useful that we decided to enhance it and move it to the SDK for Windows Phone 8. In this post we discuss the improvements we’ve made to the control, and provide a mapping guide for Windows Phone developers who are already using the Windows Phone Toolkit 7.1 version of the LongListSelector.

If you prefer to read XAML instead of plain text, you can go straight to the samples and explore them:

For more info about how to use the LongListSelector, see How to display data in a grouped list in LongListSelector for Windows Phone 8.

Let’s dig a little deeper into various enhancements we’ve made to the control. The following sections are provided in this post.

FAQs

LongListSelector moved to Windows Phone 8 SDK and to ROM

The LongListSelector control is now a part of Microsoft.Phone.Controls namespace in Microsoft.Phone.Controls.dllassembly. This means it’s now a fully supported, high-quality control shipped by the Windows Phone Development team. We also moved the assembly to ROM to take advantage of the internal off-thread input and the render thread architecture. This means the control is optimized for the full potential of Windows Phone.

The Microsoft.Phone.Controls.dll assembly also contains other phone-specific controls, such as Panorama and Pivot. These controls also get the performance benefits of being in ROM, including reduced memory consumption (~50% reduced memory for a basic app) and improved touch performance, especially when you have data being loaded in the panorama view.

Sticky headers

The native Windows Phone grouped list has the headers stick to the top as you scroll. The LongListSelector control in Windows Phone 8 has the same smooth effect.

Note the headers in the following screenshots.

Figure 1 - Notice group header "a"

Figure 2 - Scrolling up, notice how "a" sticks to top

Figure 3 - Notice how the group header "b" pushes "a"

Figure 4 - Now "b" is sticky, same as "a"

Grouped grid layout

In Windows Phone 8, LongListSelector supports grid layout, which is more than just the WrapPanel that’s available in the Windows Phone Toolkit. The LongListSelector grid layout is virtualized, which provides better performance. The following screenshots are from the PhotoHubsample.

Figure 5 - LongListSelector's Grid layout

Figure 6 - Jumplist's List layout.

The following code is an excerpt of the XAML for the LongListSelector from the PhotoHub sample.

C#
<phone:PhoneApplicationPage.Resources>
 <phone: JumpListItemBackgroundConverter x:Key="BackgroundConverter"/>
        <phone:JumpListItemForegroundConverter x:Key="ForegroundConverter"/>
 
        <Style x:Key="JumpListStyle" TargetType="phone:LongListSelector">
            <Setter Property="LayoutMode" Value="List" />
            <Setter Property="Margin" Value="12,12,0,0"/>
            <Setter Property="ItemTemplate">
                <Setter.Value>
                    <DataTemplate>
                        <Border Background="{Binding Converter={StaticResource BackgroundConverter}}" 
                            Width="470" 
                            Height="70" 
                            Margin="6">
                            <TextBlock Text="{Binding Key}"
                                Foreground="{Binding Converter= {StaticResource ForegroundConverter}}"
                                Font Family="{StaticResource PhoneFontFamilySemiBold}"
                                  FontSize="28"
                                Padding="2"
                                VerticalAlignment="Bottom"/>
                        </Border>
                    </DataTemplate>
                </Setter.Value>
            </Setter>
        </Style>
</phone:PhoneApplicationPage.Resources>
<phone:LongListSelector Name="PhotoHubLLS" Margin="13,-30,0,0"
    ItemsSource="{Binding GroupedPhotos}"
                         ItemTemplate="{StaticResource ItemTemplate}"
    GroupHeaderTemplate="{StaticResource GroupHeader}"
    JumpListStyle="{StaticResource JumpListStyle}" 
    IsGroupingEnabled="True"
    LayoutMode="Grid" 
    GridCellSize="108,108"/>

Let’s look at some examples of interesting properties found in this code.

LayoutMode – Indicates whether the collection in the context should be displayed as a list or as a grid. In the preceding XAML example, LayoutMode is set to Grid as a property on the LongListSelector, and set to List as a property on JumpListStyle.

JumpListStyle– Provides the style for the jump list items.

GridCellSize – Indicates the size of each cell in the grid. This property has to be set on the LongListSelector or the JumpListStylewherever the grid layout is to be rendered.

Converters - Note that the JumpListItemBackgroundConverter and JumpListItemForegroundConverterare needed to convert the foreground and background colors of the jump list item (group header of a group) whether or not it has items in the group. These converters also are part of the SDK and are in the same Microsoft.Phone.Controls namespace.

Figure 7 - Value converters shading empty group jump list items

The default foreground and background colors match the first-party app. You can customize it to align with your design needs using the Enabled and Disabled properties as shown here:

XAML
<phone:JumpListItemBackgroundConverter Disabled="Bisque" Enabled="Aqua" x:Key="BackgroundConverter"/>
<phone:JumpListItemForegroundConverter Disabled="Azure" Enabled="BlueViolet" x:Key="ForegroundConverter"/>

Improvements to infinite scrolling scenarios

Earlier we spoke about infinite scrolling for the Windows Phone Toolkit 7.1 LongListSelector. As you approach the end of the visible list when scrolling, the LongListSelector automatically fetches more items and adds them to the list, which gives you a sense of infinite scrolling. We made this scenario simple to implement in Windows Phone 8. The following code from the Twitter Search sampledemonstrates how easy it is to implement:

XAML
<phone:LongListSelector Name="resultList" Grid.Row="1" 
    DataContext="{StaticResource viewModel}" 
    ItemTemplate="{StaticResource ResultItemTemplate}" 
    ItemsSource="{Binding TwitterCollection}" 
    ListFooter="{Binding}" 
    ItemRealized="resultList_ItemRealized"/>

C#
void resultList_ItemRealized(object sender, ItemRealizationEventArgs e)
{
    if (!_viewModel.IsLoading && resultList.ItemsSource != null && resultList.ItemsSource.Count >= _offsetKnob)
    {
        if (e.ItemKind == LongListSelectorItemKind.Item)
        {
            if ((e.Container.Content as TwitterSearchResult).Equals(resultList.ItemsSource[resultList.ItemsSource.Count - _offsetKnob]))
            {
                _viewModel.LoadPage(_searchTerm, _pageNumber++);
            }
        }
    }
} 

The ItemRealized event is raised every time a LongListSelector item acquires a UI container to be displayed on the screen. In other words, every time an item enters the UI buffers above or below the current viewport, the ItemRealized event is raised. The event argument property ItemKind indicates whether the UI container is an Item, ListHeader, GroupHeader, or ListFooter. Using the property Container.Contentyou can get the actual object associated with the UI container that was realized. This way you can monitor the objects within the UI container buffer.

Note how the app code in this example contains a private variable _offsetKnob. This helps fine-tune the LongListSelector scrolling experience by helping to determine when to load more items depending on how heavy your item template is, or on how slow the response is from the service sending the data.

Globalization – SortedLocaleGrouping

When you group contacts in alphabetical order, you want to do this in all languages. You could provide your own globalized, sorted alphabet characters for group headers. However, using your own alphabet strings will not guarantee 100% matching with the phone first-party contacts list. So we introduced a class called SortedLocaleGrouping that provides a set of alphabets that are the same as those used by the first party. In the PeopleHub sample, SortedLocaleGrouping (from Microsoft.Phone.Globalization namespace) is used in one of the helper types, AlphaKeyGroup(which also is very highly recommended).

You get the group display names by using the SortedLocaleGrouping.GetGroupDisplayNames property to populate your groups. Then use the GetGroupIndexmethod to classify your contacts list.

SupportsPhonetics property

This is a unique property and we have included it in SortedLocaleGrouping. In some cultures, such as ja-JP, last names are written in a different script and are pronounced differently depending on the region or background.

Here’s an example:

String of LastName	Yomi/Pronunciation	Group based on Yomi	Group without Yomi
新井 (display string)	Nii --> にいい (in Hiragana) or ニイイ (in Katakana)	ナ	The Globe icon
	Arai --> あらい (in Hiragana) or アライ (in Katakana)	ア	The Globe icon
	Shinkyo --> しんきょ (in Hiragana) or シンキョ (in Katakana)	サ	The Globe icon

This is a common phenomenon catching on in different cultures, and the first-party contacts list will be grouped based on the Yomi that is passed in. If no Yomi is passed in, it will return the default, same group (equivalent to other or globe).

You usually would use the SupportsPhonetics property when classifying the contacts into groups and if you have the Yomi (pronunciation) database that you can access via a service or other means for the specific culture. The code between the //EXAMPLE comments in the following example is from one of the helper methods that shows how you would use it if you have a database of the pronunciations (Yomi) for various names.

C#
/// <summary>
/// Create a list of AlphaGroup<T> with keys set by a SortedLocaleGrouping.
/// </summary>
/// <param name="items">The items to place in the groups.</param>
/// <param name="ci">The CultureInfo to group and sort by.</param>
/// <param name="getKey">A delegate to get the key from an item.</param>
/// <param name="sort">Will sort the data if true.</param>
/// <returns>An items source for a LongListSelector</returns>
public static List<AlphaKeyGroup<T>> CreateGroups(IEnumerable<T> items, CultureInfo ci, Func<T, string> keySelector, bool sort)
{
    SortedLocaleGrouping slg = new SortedLocaleGrouping(ci);
    List<AlphaKeyGroup<T>> list = CreateDefaultGroups(slg);
 
    foreach (T item in items)
    {
        int index = 0;
        // EXAMPLE
        if (slg.SupportsPhonetics)
        {
            //check if your database has Yomi string for item
            //if it does not, then do you want to generate Yomi or ask the user for this item.
            index = slg.GetGroupIndex(Yomiof(item));
        }
        // EXAMPLE
        else
        {
            index = slg.GetGroupIndex(keySelector(item));
        }
 
        if (index >= 0 && index < list.Count)
        {
            list[index].Add(item);
        }
    }
 
    if (sort)
    {
        foreach (AlphaKeyGroup<T> group in list)
        {
            group.Sort((c0, c1) => { return ci.CompareInfo.Compare(keySelector(c0), keySelector(c1)); });
        }
    }
 
    return list;
}

FAQ

Why use IList instead of IEnumerable for ItemsSource?

You have to know how many elements there are and there is no Count property on IEnumerable. You also have to be able to access the items by index, not just in the forward-only, one-at-a-time way that enumerators do. If ItemsSource accepted IEnumerables or an IEnumerable of IEnumerables, you’d have to convert them to lists internally using the default method of iterating over every single item. This conversion would rule out data virtualization, which could cause poor performance without the app author knowing why. Worse yet, the author might think that it is the status quo and simply accept a longer start time. This was one of the complaints about the original toolkit LongListSelector. Now, if an app author has only an IEnumerable set of data, the developer can simply call ToList() for the default conversion to an IList but the developer also has the flexibility provide their own IListimplementation.

Is LongListSelector recommended instead of ListBox?

Yes! We have designed the LongListSelector specifically for phone scenarios and we encourage people to use the LongListSelector instead of ListBox for phone apps.

Announcing Sculpt Comfort Mouse & Mobile Mouse

Brandon LeBlanc — Thu, 23 May 2013 16:00:00 GMT

Today, we’re announcing two new mice designed specifically for Windows. These are the first mice from Microsoft to include a Windows button on them, giving you quick and easy access to specific features in Windows – and, in the case of the Sculpt Comfort Mouse, more advanced functionality in Windows 8.

Sculpt Comfort Mouse

The Sculpt Comfort Mouse is a perfect companion to the Sculpt Comfort Keyboard we announced last fall. The Sculpt Comfort Mouse has a touch-sensitive blue strip on its side called the Windows touch tab that makes it easy to navigate Windows 8 with just the touch or swipe of a finger. When pressed, it of course takes you to your Start screen, just like the Windows buttons on keyboards, PCs and tablets.

But it does more than just take you to your Start screen. If you swipe up on the blue strip, it cycles through all your open Windows Store apps in Windows 8. And if you swipe down, it will reveal all the open apps (on the left side of your screen) for you to select the one you want. You don’t have to worry about a tiny USB transceiver since the Sculpt Comfort Mouse uses Bluetooth to connect to your Windows PC or tablet. It also has a comfortable ergonomic design and our BlueTrack technology to be used on pretty much any surface.

The Sculpt Comfort Mouse will be available in June for an estimated retail price of $39.95 (U.S.).

Sculpt Mobile Mouse

The Sculpt Mobile Mouse is the latest evolution of the Wireless Mobile Mouse 3500 – with a Windows button which works great on Windows 7 or Windows 8.

Like the Sculpt Comfort Mouse, it also has four-way scrolling – meaning you can scroll sideways by tilting the scroll wheel to the right or left in addition to the vertical scrolling you’re used to. This makes navigating the Start screen in Windows 8 or apps that scroll horizontally a breeze. The Sculpt Mobile Mouse has a compact design, a tiny wireless USB transceiver, and BlueTrack technology.

The Sculpt Mobile Mouse will be available in May for an estimated retail price of $29.95 (U.S.).

Speed dial: 6 tips for quicker calling on Windows Phone 8

Matt Lichtenberg — Wed, 22 May 2013 22:07:20 GMT

With everything else it can do, it’s sometimes easy to forget that Windows Phone is still, well, a phone. Looking for ways to call someone a little quicker? Here are a few tap-saving shortcuts I’ve discovered along the way.

1. Call back quickly. It never fails that when my wife and I need to sync up, I miss her call or she misses mine. To increase the odds of catching her, I tap Phone on my Start screen, and then tap the Phone icon next to her name in call history to ring back faster.

2. No answer? Try another number. Even if I call her back a few minutes later, I still might miss her. Instead of leaving voicemail, I’ll tap End call, tap her name at the top of the screen, and then tap one of her other numbers. (Tip: You’ll need to be quick because the name only appears for a couple of seconds.)

3. Go double wide. Another way I try to save a tap or two is to increase the size of my Phone Tile. Then if I miss a call or get a new voicemail, it shows up right there—no need to go to call history. Just tap and hold the Phone Tile on Start, and then tap the icon on the bottom right to resize the Tile.

4. Turn a number into a name. Instead of hunting through call history and trying to remember which number goes with which person (I’ve guessed wrong more than once), I’ll save the number as a contact so I can quickly find and call them next time. Just tap Phone > History, tap the phone number, and then tap Save. I can tap New to make them a new contact, or add the number to a contact I already have. Check out this article on the Windows Phone website to learn more about saving contacts on your phone.

5. Can’t talk when someone calls? Text instead. If you have the latest update for Windows Phone 8 you might’ve already discovered this new feature, which I really love and use a lot. When a contact calls from their cell phone and you can’t talk, just tap Text reply, then tap a response and away it goes. I’ve customized my replies, too, so I can say what I want with two taps. This video shows the feature in action.

6. Who’s calling? Let Windows Phone tell you. I don’t always have my phone sitting next to me at home, so I have it announce the caller’s name out loud. That way, I know if I really need to run and pick up. To turn this feature on, go to Settings > Ease of access > Speech for phone accessibility. This setting turns on a few more things, too, including the ability to speed dial and forward calls with your voice. To learn more, see Use Speech on my phone.

I hope one or two of these were new to you. Have any tips or things you do to speed up calling? I’d love to hear ‘em!

Testing your Windows Phone app – Part 2

Adam Denning — Tue, 21 May 2013 20:07:00 GMT

This blog post was authored by Craig Horsfield, a Senior SDET on the Windows Phone Test and Operations team.

- Adam

Testing your app throughout the development process can help you create a really great Windows Phone app. Testing helps ensure that your app is effectively represented in the Windows Phone Store as an app that offers Windows Phone users a high level of performance and quality. A small investment in the key areas described in this post can help you bypass common errors early in the development process, and help you get positive results in the long term. This post is part 2 of a 3-part series that outlines key test areas that you should consider before submitting your app to the Store. See part 1 for additional details.

Push notification and Live Tiles

Live Tiles

Live Tiles are updated through push notification or through an app’s periodic background agent. When testing these areas, you should accelerate the update time so that you can test more rapidly. For more info, see Tiles for Windows Phone.

Test scenario	Details
1. Verify that your Live Tile updates.	Verify that the Live Tile updates after it has been pinned to Start.
2. Verify that your Live Tile stops updating.	If this setting is disabled in the app, make sure the Live Tile stops updating.
3. Verify that the Live Tile updates via a periodic agent.	If the Live Tile is updated via a periodic agent, verify the update on all network types, and verify that the Live Tile updates when there is no network, for example, in Airplane mode.
4. Verify that the Live Tile is working and present after an app upgrade.	None.
5. Verify that the Live Tile is working and present after an app upgrade and subsequent restarting the device.	If updating the app, make sure that you don’t change the TokenID in the WMAppManifest.xml file. This results in your Live Tile being removed from Start when the device is restarted.
6. If using a background agent, verify that the agent doesn’t crash or terminate.	This results in disabling the agent and Tile updates will fail.

Notifications

Apps that use notifications normally are used within background agents. Test these notifications to ensure that they work properly. For more info, see Notifications for Windows Phone.

Test scenario	Details
1. Verify that notifications are received.	None.
2. Verify what happens when you tap the notification.	Tapping the notification launches the user into the app in the correct state.
3. Verify that the app doesn’t overuse toast notifications.	None.

Agents

Background agents provide key abilities for an app, but they also introduce some specific test considerations. Agents can be disabled and enabled in the phone’s settings, on the Settings > Application > Background Tasks screen. The app needs to be aware of the state of the agent. Resources available to agents also are restricted. A key point to remember is that when running in the debugger, these restrictions are not enforced so it’s important to test your app outside of the debugger and track the resource that it is using. For more info, see Background agents for Windows Phone.

Test scenario	Details
1. Verify initial app start.	The agent starts when it’s needed.
2. Verify that the app handles state in which the agent has been disabled by the user in Settings\Application\Background Tasks.	Additionally, verify that the app performs as follows: App notifies the user that it’s not available and continues to work as expected. App notifies that the agent is needed and re-enables it.
3. Agents are disabled in low-battery conditions - test that the app can handle these states.	None.
4. Agents that crash or are terminated by the OS for exceeding resources, on two successive crashes will be disabled. Ensure your app handles this state.	In this state the foreground app has to reschedule the agent. This state can be queried from the agent API. For more info, see Background agent best practices for Windows Phone.
5. Resource-intensive agent only runs when on power and Wi-Fi. Ensure app handles this correctly.	None.
6. Verify that the agent stays below the required CPU and memory caps.	None.

This table lists the required CPU and memory caps, by agent on Windows Phone 8:

Agent	CPU	Memory
CBE	10%	N/A
GBA	10%	11 MB
BAP	10%	20 MB
FA	5%	10 MB
VoIP agent	20%	60 MB

Media, audio, and video

Media, audio, and video throughout your app should be tested. Consider these test scenarios in the table below. For more info, see Media for Windows Phone.

Test scenario	Details
1. Preserve audio state.	If your app plays an audio sound (clip) when it starts, your app should not pause the currently playing audio. The app should preserve and not interfere with the currently audio playing on the device. If your app plays back audio content from a background agent or a foreground app, your app should pause any currently playing audio.
2. Verify the Universal Audio Control during audio playback.	Verify Play. Verify Pause / Resume. Verify Skip Next / Skip Previous. Skip to last and back to the first track, etc. Some apps may take time to process these calls. Verify that the UI is set to disabled while the app is processing these calls to prevent multiple invokes. Verify volume controls. Audio continues under lock. Audio continues when app is on the back stack. Verify all expected codecsthat the app offers can be played back. Track info is displayed in the UI.
3. Verify audio playback via a background audio agent.	Test all of the above test cases. Audio continues when the app is terminated but the background agent is allowed to continue. Audio continues to play when device screen is locked. App agent remains below the app 20-MB cap.
4. Media Source	Verify media from a network stream. Verify media from the app’s ISO store. Verify media playing from the media library on the phone. (This case requires the correct capability in the app manifest.)
5. Video playback	Verify all states: Play from start Pause, resume Skip forward and back Change states rapidly
6. S-Video playback in FAS scenarios	On navigate away event, the app needs to record the current media stream location. Play media stream return to the phone start page and then switch back to the app. Verify the stream is preserved, should continue from the previous point. Play media stream and force the app to tombstone via Visual Studio. In this case, the app should continue from previous point but will have to load the stream and forward it to the location saved in navigate away and deactivated events.
7. Bandwidth	Verify media stream playback on different networks and bandwidth. App should adjust playback quality and codec as need. Verify network dropped scenario and the app handles this and informs the user correctly. Visual studio phone emulator can manipulate the network quality and type to aid in this testing.
8. Media hub integration	Verify app is visible in the Media hub, manifest must have HubType=1. App has to use MediaHistory and MediaHistoryItemclasses in this scenario. Verify post market place ingestion where the correct capabilities are set on the app manifest to enable it in the hub. (Use the App Beta submission process to test this.) App must update the, ‘now playing’ tile, ‘history’ and ‘new’ list. Verify app plays correct stream when launched from history or new list.
9. FM Radio	App is not compatible with all hardware and versions of Windows Phone. Test app on the correct platform. Verify that app sets the correct region based on the phone location; this enables the correct frequency stepping. If incorrect it will not tune well or find stations. Set the correct power modes. For example, verify that the user is not playing media from the FM radio, then set RadioPowerMode to off.

Geolocation

With Windows Phone 8, you can create apps that use info about the phone’s physical location. Scenarios for location-aware apps include checking the user into a web service using the user’s instantaneous location, and tracking the user’s location as it changes over a period of time. The location data the phone provides comes from multiple sources, including GPS, Wi-Fi, and cellular. The visual studio phone emulator can be used to simulate these location changes. The location can be moved manually or simulate a sequence of location changes. For more info, see Location for Windows Phone 8.

Test scenario	Details
1. Prevent PositionChange events from firing too often and placing CPU processing load on the app.	Set the MovementThreshold property to the appropriate value for the app needs and make sure that events fire only outside of that threshold.
2. Handle the unknown location state.	Ensure the app can handle NA values. Test the app when it has no location state.
3. Test a large change in location data so that any internal calculations in the app do not fail in these cases.	For example, position changes greater than 1 degree. This can happen if the phone has had no valid location data for some period of time.
4. Test app in all hemispheres: North/South and West/East.	Ensure that your calculations on negative degree values are correct.
5. Test 0-degree and 180-degree location for longitude and latitude.	None.

Design considerations when using location:

Test scenario	Details
1. Use a lower level of accuracy to save on battery power if applicable.	None.
2. Check the Position.Location.IsUnknown and GeoPositionStatus properties to ensure that the location is valid.	None.

Resource usage and performance

Windows Phone apps need to be designed to efficiently use and preserve the limited resources of the phone platform. You want to design your apps to use the least possible CPU cycles, to access networks efficiently and purposefully, and to make the best use of visual components—graphics, bright colors, and themes use more power than a simpler UI.

Test areas to consider:

Test scenario	Details
1. Check for a nonresponsive or jerky UI.	This could be caused by long-running activity on the UI thread.
1. Check for Memory leaks – repeat scenarios multiple times to detect memory leaks during specific sequences.	Repeat page navigation could increase app memory.
2. Check for rapid battery drain.	Can be caused by using the app for long periods of time.

Tips and tools:

The Visual Studio app profiler, on the debug menu, is a key tool for looking into app memory and CPU usage.
Using the EnabledFrameRateCounter/EnableRedrawRegionscan be useful when app testing.
Use APIs in the DeviceStatus class track memory usage in the app, especially ApplicationCurrentMemoryUsage and ApplicationPeakMemoryUsage.
See App performance considerations for Windows Phone for an overview of app performance for Windows Phone.

In part 3 of this series, we’ll discuss additional areas and testing approaches to consider, including to network resources, device-specific tests for hardware variations, display resolution, app upgrade, common Store test cases, and real-world testing.

Use your HTML5 skills, port your PhoneGap app to Windows Phone, and win prizes

JC Cimetiere — Mon, 20 May 2013 19:09:00 GMT

Many of you have heard about PhoneGap (aka Apache Cordova), the popular open source framework you can use to create mobile apps using HTML, CSS, and JavaScript.

New themes and wallpapers: Alaska, New Zealand, Sweden and sweets!

Jennifer Shepherd — Fri, 17 May 2013 23:15:39 GMT

Many years ago, I spent a week visiting my brother in Alaska. At the time, he was working on a fishing boat out of Homer, and I spent several days on the boat enjoying the sights of Kachemak Bay and the Kenai Peninsula. The impression that struck me immediately as my flight descended toward the tarmac, and that stayed with me throughout my visit, was just how huge and near the mountains looked; in fact, every aspect of nature seemed larger, closer, and more vivid. That’s one of the things I like about the photographs of Kyle Waters, featured in our new Alaskan Landscapes theme—the immensity and immediacy of Alaska’s natural landscape really comes through.

On the subject of great landscapes, in my previous blog post I promised you more of Ian Rushton’s HDR photography, and I’m pleased to be able to follow through with not just one, but two new themes. The first is a tour of Queenstown and the surrounding landscape, including the shores of Lake Wakatipu and views of the Kawarau and Shotover rivers.

The other, and my new favorite, is a walk through the lush greenery of One Tree Hill Domain and the adjoining Cornwall Park, in Auckland, New Zealand. I’m sure I don’t need to tell you what song I hear in my head when looking at these images!

Fans of our Swedish seasonal themes might have noticed when we published the Swedish Autumn, Swedish Summer, and Swedish Winter themes several months ago, that something was missing. You’ll be relieved to know that we’ve finally filled in the missing season with Swedish Spring.

For a total change of pace from landscape photography, I’m pleased to present a theme featuring the quirky artwork of illustrator Karyn Servin. The Delectable Designs theme’s cartoony cupcakes, popsicles, and other goodies will bring a cheerful pop of tasty color to your desktop.

If you have an older version of Windows that can’t use themes, or if you prefer to use a single desktop background, be sure to check out the fresh wallpapers. Here are just a few:

We also added a new tab to the Desktop backgrounds page, specifically for panoramic wallpapers. If you have Windows 8 or Windows RT, these wallpapers will automatically extend across dual monitors that have the same resolution setting. But you can also enjoy them on an older version of Windows or on a single monitor. And as I explained in an earlier post, you can use wallpapers on your Windows 8 or Windows RT lock screen, as well.

By the way, you can control how wallpapers fit to the screen in the Desktop Background section of Personalization in Control Panel. To see the full width of a panoramic image on a single monitor, choose Fit in the Picture Position menu. The image will be scaled down to fit the width of your monitor, and you'll see black above and below it. To fill your entire monitor but see only the middle of the image, choose Fill in the Picture Position menu. This will fit the image to the height of your monitor, and crop off the right and left edges.

As always, keep checking back on the Personalization Gallery – we’ll have even more new themes and wallpapers for you next month.

Adobe Photoshop Express for Windows 8 now available in the Windows Store

Brandon LeBlanc — Fri, 17 May 2013 20:50:56 GMT

Adobe Photoshop Express for Windows is now available for download from the Windows Store. Photoshop Express for Windows 8 comes with a variety of features to quickly edit your photos on your Windows PC or tablet.

You can do the basic photo enhancements such as crop, straighten, rotate, flip, or remove red-eye. You can adjusts color, contrast, and brightness all at once. And you can use “slider controls” to enhance contrast, exposure, and white balance, or let the app auto-correct it for you.

But my favorite feature are the quick one-touch filters – called “Looks” – to add different effects to your photos. The app comes with 15 free “Looks” with additional premium “Looks” available for purchase from Adobe.

And of course once you’re done editing your photo, you can quickly share your photo out to folks on your favorite social networks or save to your PC.

XAudio2 Performance and Battery Considerations for Windows Phone 8

Adam Denning — Fri, 17 May 2013 18:50:31 GMT

This blog post was authored by Joao Lucas Guberman Raza, a program manager on the Windows Phone team.

- Adam

In this post we cover important information for Windows Phone 8 developers who use the XAudio2 APIs, including best practices for battery performance. XAudio2 is a high-performance audio API available in Windows 8, Xbox 360, and Windows Phone 8. An app developer can use XAudio2 to create audio graphs in which they can treat each audio source in the graph as a distinct “voice.” The developer can apply different effects to each of the “voices.”

In Windows Phone 8, the XAudio2 engine must be aligned with the life cycle of the app. This means that if an app is suspended, the app that’s using XAudio2 must force the XAudio2 engine to stop. When the app resumes/rehydrates, if it is designed to resume sounds using XAudio2, it must restart the XAudio2 engine. Significant battery drain can occur if an app doesn’t stop the XAudio2 engine when the app is suspended, and the engine continues to run.

To avoid this scenario, an app must call IXAudio2::StopEngine when the app is suspended as described in the Native audio APIs for Windows Phone 8. When the app resumes, it should call IXAudio2::StartEngine. For Silverlight and Direct3D with XAML apps, the suspend/resume APIs are the Suspended and Activated events. For Direct3D native-only apps, the suspend/resume APIs are the Suspending and CoreView Resuming events.

The following code examples show you how you can do this in a pure native Direct3D app.

First create the XAudio2 object, which handles the XAudio2 sound APIs.
C++
1. IXAudio2* pXAudio = NULL ;
3. if( FAILED(XAudio2Create(&pXAudio, 0, XAUDIO2_DEFAULT_PROCESSOR) ) )
4. return false ;
6. if ( FAILED(pXAudio->CreateMasteringVoice( &pMasterVoice ) ) )
7. return false;
Then, on the suspending/resume events, set up the XAudio2 object to call StopEngine and then StartEngine. In the following example, we use the default events in the Windows Phone 8 SDK template for Direct3D native-only apps.
C++
1. void WindowsApp::Initialize(CoreApplicationView^ applicationView)
2. {
3. applicationView->Activated +=
4. ref new TypedEventHandler<CoreApplicationView^, IActivatedEventArgs^>(this, &WindowsApp::OnActivated);
6. CoreApplication::Suspending +=
7. ref new EventHandler<SuspendingEventArgs^>(this, &WindowsApp::OnSuspending);
9. CoreApplication::Resuming +=
10. ref new EventHandler<Platform::Object^>(this, &WindowsApp::OnResuming);
11. }
13. void WindowsApp::OnSuspending(Platform::Object^ sender, SuspendingEventArgs^ args)
14. {
15. pXAudio->StopEngine() ;
16. }
18. void WindowsApp::OnResuming(Platform::Object^ sender, Platform::Object^ args)
19. {
20. pXAudio->StartEngine() ;
21. }

With these steps, you can design your app to follow best practices for battery consumption when you use the XAudio2 APIs. It’s important to note that this is one of many best practices you can use in your app. To learn more, see also local folder best practices for Windows Phone, localization best practices for Windows Phone, and background agent best practices for Windows Phone.

App roundup: 7 apps for better health

Kirsten Ballweg — Fri, 17 May 2013 18:00:00 GMT

As I mentioned in a previous post, I’m a writer for Windows by day, and a musician by night. Musicians don’t always have the best health habits. Late nights, hanging out in smoky clubs, and getting paid in drink tickets have taken their toll on my health. So I decided to take a look at some apps that might get me back on the health wagon.

Heart Age

Before starting an exercise regimen, I thought it might be a good idea to figure out if my heart could handle it. Heart Age is a free app that estimates your heart's "true age" based on info like your height, weight, frequency, and intensity of exercise, cholesterol, and blood pressure.

According to the test, I have the heart of a 28 year old. That sounds good to me! I ♥ Heart Age!

Bodeefit

Want a quick but brutal workout? Bodeefit has workout plans based on time (most are around 10-15 minutes) or number of rounds (the time these take depends on how fit your “bodee” is). The equipment you need is minimal—basically a floor, a wall, a box (for diabolical box jumps), and a bench (for dips and possibly for jumping over). There’s something reassuring about the video clip examples in this app. Watching a guy jumping on the box made me think that I could actually do that too. I was wrong. Box jumps are hard! But the videos make it fast and easy to figure out how to actually do the exercises—a lot easier than reading a description on how to do each move.

With workouts named Furious 10, Fire Breather, and Sit, Sit up, Crawl! I'm strangely looking forward to seeing what new form of torture awaits me next.

If you want to save your results, you can sign up for a free Bodeefit account (or upgrade to a Pro membership for additional benefits). With the free membership, you’ll get daily workouts sent to your email address, and a paleo recipe from PaleOMG once a week. The paleo diet, if you haven’t heard of it, is based on what Paleolithic man might have eaten. So basically: meat, fish, certain vegetables, and no sugar, carbs, or dairy. The recipes actually look delicious and include banana bread, brownie trifle, and cake (with substitutions for ingredients not allowed on the diet). Those cave men ate a lot better than I thought!

BallStrike

Taking a workout and disguising it as a game is sheer brilliance. There’s no Mario or Ms Pac Man character in the game of BallStrike, though. Through the magic of your webcam, you’re the main character. Balls appear on the screen, and it’s your job to twist, turn, kick, hit, and jump around to destroy the balls. Just watch out for those pesky bombs. You want to destroy them, not the other way around.

At the end of your session, you can share photos of yourself on Facebook, through email, and on other sites.

The first few levels of the game are completely free. To get the full version of the app (complete with 12 levels of ball-striking fun) it will cost you US$3.49, but that seems a small price to pay if you like to kick and punch things as much as I do.

MyPlate Calorie Tracker from LIVESTRONG.COM

Losing weight, I’ve been told, is mostly about what you put and don’t put into your mouth. Exercise certainly helps and is very important for overall health and fitness, but as far as actual pounds go, it’s all about the food.

The MyPlate Calorie Tracker has become my favorite app for tracking what I’m eating. It’s easy to add foods. Tap or click the + button under the meal you want to record, and then start typing. Then just pick from the results and, if necessary, adjust your serving size. With a database of more than 1.3 million food items (including many popular brands and restaurant items), you’re bound to find the foods you’re eating. Foods you eat often are shown in a list of recently eaten foods, so it’s easy to add them.

You can also track the amount of water you’re drinking and how much and what type of exercise you’re doing.

When you first start the app (after you sign in or create a free account), you decide how much weight you want to lose each week. MyPlate Calorie Tracker crunches the numbers for you. You can see how many calories you have left to consume, and how many you’ve used each day. I’m going to try using this for a full week. Hopefully the scale will say 2 pounds lost by next Friday.

HealthVault

Insurance info, health history, doctor info – HealthVault brings them all together in one place. I signed in, and then plugged in my info. Not only does Health Vault help track calories and weight, it can keep track of any health conditions you want to enter (oh, my aching back!).

Many popular exercise or heath devices (like pedometers, blood pressure monitors, blood glucose monitors, and even some scales) work with Health Vault, so you can save all your data in one place. There are over 200 devices that are compatible, and the list is growing. Have a Fitbit? You’re golden.

If you use other health apps, they can plug into HealthVault too. So if you have prescriptions at Walgreens, CVS, or various other pharmacies with apps, HealthVault can pull in your prescriptions so all of your health info is in one place.

You can also track health information for your family. So if you have kids or aging parents, HealthVault can help you out.

KinectHealth

When it comes to working out, I’m motivated by competition. The KinectHealth app is perfect for people like me. It offers virtual training videos that use your webcam to monitor your activity level. Then, the app shares info about your workout with your friends who also use KinectHealth, so you can all stay motivated.

When you watch a workout video, you'll see your trainer on the main part of the screen, and on the left, you’ll see a video of yourself working out, with your stats. At the top of the screen are friends and trainers who've taken the training already. As the video plays, you can see how your friends were doing at that specific point in the video. Your friends don’t need to be doing the same video at the same time—KinectHeath saves their data and just replays it back to you. You’ll see how many calories they burned and if they were calm (a purple circle on their profile picture), active (a green circle), or hyper (a red circle).

There were a good variety of video workouts available when I started the app (including yoga, Pilates, cardio, and strength). I decided to try out the Legs are Burning video, with the trainer, Jason. This workout delivered. As I did my squats and lunges along with Jason, my PC webcam monitored my activity. By the end of the training I was in the hyper zone.

As you reach your fitness goals, your progress is shared with friends (and vice versa) so you can cheer each other on, or at least get guilted into working out more. Effective!

Digital Health Scorecard

From Johnson & Johnson, the makers of a lot of health-related items from baby powder to Nicorette®, comes the Digital Health Scorecard app. Plug in some numbers (the app walks you through 7 questions) and you’ll get your overall health score, based on The World Health Organization’s “Global Burden of Disease” data.

The lower your score, the higher your chances of developing chronic diseases like diabetes, heart disease, or cancer.

On the results screen you can see how various changes in your overall lifestyle might affect your score by using the “What if?” button.

If you’re currently a smoker, you can see how your score would change if you quit. Or if you regularly enjoy a martini or two at lunch, you can drop your weekly drink number and see how much your score goes up. Making the comparison can be pretty motivating. But there’s no way I’m completely giving up my martinis. I like olives too much. And olives aren’t bad for you, at least in moderation, right?

Here’s to your health! (Clink!)

Tips to grow your app revenue through in-app purchase

Bernardo Zamora — Thu, 16 May 2013 17:28:18 GMT

Your Windows Phone 8 app presents three potential sources of revenue: app sales, in-app advertisement, and in-app purchases.

In a previous blog post I wrote about what you can sell in your Windows Phone 8 app by adding in-app purchase. You can:

Sell digital items.
Offer consumables (items that are used a set number of times per purchase) and durables (items purchased and then owned by the buyer).
Extend app features: add game levels, app features, and game currency, for example.

Today, I want to share recommendations and guidance to optimize the experience and effectiveness of in-app purchase in your Windows Phone app.

In-app purchase trends in the Windows Phone store

In-app purchase was added with the launch of Windows Phone 8 as a way to expand the value of apps and offer the possibility of additional revenue. It represents a growing revenue source in the Windows Phone Store: already 40% of the top 15 highest-grossing developers have apps that use in-app purchase.

Consumer adoption of in-app purchase varies by market, depending on regional trends, consumer preferences, and other regional differences. Central Europe, China, France, Middle East and United States are the markets where consumers purchased most in-app items, as a percentage of app downloads, compared to other markets.

In-app items are used in all categories of Windows Phone 8 apps in the Store. The categories with highest use of in-app purchase are Games, Tools and Productivity and Books & Reference. So in-app purchase can be used in all types of apps.

Use of in-app purchase by app category

Insight from the apps with highest in-app revenue

We analyzed the 30 apps and games with the highest in-app purchase revenue in the Windows Phone Store, and found some interesting trends, common characteristics, and best practices. Here’s what we discovered.

In-app purchase can add value to both games and non-game apps: the top grossing list includes 20 games (shooters, puzzles, racing, family, and other types of games) as well as 10 non-game apps (audio book, health/fitness, tools/productivity, navigation, and sports).

Start with a great app: All these top 30 apps are high quality, engaging apps with beautiful graphics and compelling sounds and music. All apps have 4-star ratings or higher, and user comments posted in the Store show that users love these apps, and therefore are willing to purchase the in-app items to enhance their experience. All these apps are easy to use and intuitive.

Use the ‘freemium’ business model: Most of these apps are free and offer in-app purchase extends the value of the app (90% of the apps are free and 10% are available in a paid version only). There are a few apps that are not free, and these apps are from developers with a brand name strong enough that users will know the quality or utility of the app. Very few of the apps, less than 5, use advertisement in the apps: most of these top developers focus only on in-app purchase to generate revenue.

Offer value even without purchase, and extend the app through in-app purchase: 28 of the 30 apps are useful even without in-app purchase. The apps provide great value even if no in-app purchase is used. In-app purchase is used to improve the app experience:

The games use in-app consumables to offer game currency, which in turn is used to purchase items in the game. Users can earn this currency through gameplay, or accelerate gameplay through purchase.
Non-games offer content through consumables and durables (audio books, book chapters, navigation maps, more sounds) or offer additional features through durable in-app purchase (for example additional features like online backup).
Three of the five apps that have ads use in-app purchase as an option for the user to remove the ads.
Two apps use in-app purchase to unlock the full version or new levels. These apps require in-app purchase to provide value beyond the introductory level or content.

Integrate in-app purchase seamlessly: The app developers use in-app purchase as a natural extension of the app, not as an afterthought. When using these apps, users feel that they are getting a significant additional value of value through the in-app purchase, and don’t feel forced to buy the app items to be able to use the app. In-app purchase is shown on simple, clear screens that show the value of what is being purchased, and frequently offer many options so the user can choose the best one for their budget and needs.

Make the app available also on Windows Phone 7: In-app purchase is only available on Windows Phone 8, so many of these top apps have created a XAP for Windows Phone 7 and a XAP for Windows Phone 8, to offer the app on Windows Phone 7:

10 of these apps are available for free on Windows Phone 7, providing the same functionality as the Windows Phone 8 versions, without in-app purchase. A few of these apps added mobile ads to provide ad revenue in place of the in-app revenue.
5 of these apps have a paid Windows Phone 7 version that offers the capabilities of the Windows Phone 8 version with all the in-app purchases.

Rebellion: Dredd vs Zombies and Guns 4 Hire

I interviewed Chris Kingsley, CTO of Rebellion, to understand more about their Windows Phone games and how they use in-app purchase. Rebellion has two shooter games on Windows Phone: Dredd vs Zombies and Guns 4 Hire. Both games use in-app purchase, and are among the highest grossing free Windows Phone games.

Rebellion makes games for many platforms, including PC games and Windows Store games. Chris shared with me the principles that he thinks have made in-app purchase successful in their Windows Phone games:

The game has to be great.
The game has to be designed with in-app purchase from the ground up.
The game has to balance free versus paid content.
Test, test, test, with as many people as possible.

Dredd vs Zombies was designed for in-app purchase from the ground up: the game is playable from beginning to end without in-app purchase. In-app purchase is used to sell credits that are used to purchase items that make the game more fun and which accelerate leveling up.

The items are designed so they genuinely feel like they are part of the game, and they provide a better play experience.

Dredd also offers items to try out, so players can get a feel for the game items that can be purchased. This also helps increase player engagement.

Guns 4 Hire offers a variety of in-app purchase items. The player has different options to choose from, and isn’t required to purchase to play the game.

The game shows the items for purchase in a very effective way: a large display for each item, a price, and a short and clear description of what you get with the purchase.

Chris from Rebellion mentioned they have another game coming up this month for Windows Phone – Zombie HQ – which builds on the shooter template by allowing players to customize their own HQ between missions.

Adding in-app purchase to your app

In-app purchase can enhance the app experience and increase your revenue, so if you think that you have a great app or game that is a good candidate for in-app purchase, add it today! Here’s how to get started:

Understand what can be sold through in-app purchase and how to add it.

Michael Stroh — Wed, 15 May 2013 17:06:46 GMT

Here’s another classic Angry Birds title for your growing Windows Phone collection. As we previously hinted, Rovio’s Angry Birds Rio arrived this morning. The game works on both Windows Phone 7 and 8 devices. Price: $0.99.

In the game, the original Angry Birds have been caged up and shipped off to exotic Rio de Janeiro, where they eventually elude their captors and set out to rescue friends Blu and Jewel—two rare macaws you’ll recognize from the 2011 movie Rio. The scenery in the game is fresh and exciting, and the physics-based gameplay is as fun as ever—with 210 challenging levels and more than 40 bonus ones. Speaking of bonus: The Windows Phone 8 version of the game also includes Xbox LIVE achievements and leaderboards.
