    • 3/18/2014Microsoft confidential3 Tiles on Windows Phone 8
    • Live Tiles on Windows Phone • Windows phone has the unique ability to provide the end user glanceable access to the information they care most about, via Live Tiles • Push Notifications offer developers a way to send timely information to their applications even when they are not running • In Windows Phone 7.1 and later, the Local Tiles API allows apps to create and update tiles
    • Live Tiles 101 • Shortcuts to apps • All apps have at least one tile, known as the default tile • Created by user pinning your app to the Start Screen • Launch to app main page • Apps can create secondary tiles • Created programmatically • Launch to any page in your app • Static or dynamic • Tiles can be updated • Application code • Background agents • Push Notifications • In Windows Phone 7.1, only one tile size for third party apps • In Windows Phone 8.0, you can support three different tile sizes 5
    • Tile Templates and Tile Sizes •Windows Phone 8 supports three Tile templates • Flip – flips from front to back (similar to the WP 7.1 Tile template) • Iconic – clean iconic layout designed to reflect Windows Phone design principles • Cycle – cycles through up to nine images 6
    • Tile Content • The Tile content is built up from a fixed set of data properties • Data Properties for Text elements, Count elements and Image elements • Content that displays depends on the template you choose and the tile size • Not all elements need to be used • Not all elements used in all templates • WXGA resolution Image sizes • Automatically scaled for WVGA and 720p 7 Tile Size Flip and Cycle Images Iconic Images Small 159 x 159 pixels 159 x 159 pixels 110 x 110 pixels Medium 336 x 336 pixels 336 x 336 pixels 202 x 202 pixels Wide 691 x 336 pixels 691 x 336 pixels N/A
    • Flip Tile Template • Flips from front to back • Small size does not flip • Medium size is the same as the WP7.1 tile template 3/18/20148
    • Cycle Tile Template • Cycles between from 1 to 9 images • Small tile does not cycle 3/18/20149
    • Iconic Tile Template • Displays a small image in the center of the Tile and is designed to reflect Windows Phone design principles 3/18/201410
    • Primary and Secondary Tiles • Application Tile • Can be created only when user taps and holds the application name in the Application List and then selects pin to start • Tile template and Properties are set initially in the Application Manifest • Template cannot be changed programmatically • Secondary Tile • Can be created only as the result of user input in an application • The application then uses the Create(Uri, ShellTileData) method to create a Tile on Start • Because the UI will navigate to Start when a new secondary Tile is created, only one secondary Tile can be created at a time
    • Defining the Application Tile • Define your images • The standard new project templates already contain placeholder images of the correct size • FlipCycleTile*.png used for the Flip and Cycle Tile templates • IconicTile*.png used for the Iconic Tile templates • Replace these images with your own artwork 3/18/201412
    • Defining the Application Tile in the Application Manifest • Double-click WMAppManifest.xml to open using the new Manifest Editor • On the Application UI tab, set the Tile Template, optional Title and Tile Images 3/18/201413
    • Demo 1: Application Tile
    • Creating and Updating Tiles with the Local Tile API •Local tile updates(these are *not* push) •Full control of all propertieswhen yourapp is in the foregroundor background •Manage SecondaryTiles •Create/Update/Delete •Launchesdirectlyto page/experience
    • Creating Tiles public static void SetTile(RecipeDataItem item, string NavSource) { FlipTileData tileData = new FlipTileData() { //Front square data Title = item.Title, BackgroundImage = new Uri("ms-appx:///background1.png", UriKind.Relative), SmallBackgroundImage = new Uri("ms-appx:///smallbackground1.png", UriKind.Relative), //Back square data BackTitle = item.Title, BackContent = item.Ingredients, BackBackgroundImage = new Uri("ms-appx:///backbackground1.png", UriKind.Relative), //Wide tile data WideBackgroundImage = new Uri("ms-appx:///widebackground1.png", UriKind.Relative), WideBackBackgroundImage = new Uri("ms-appx:///widebackbackground1.png", UriKind.Relative), WideBackContent = item.Directions }; // Create Tile and pin it to Start. Causes a navigation to Start and a deactivation of our application ShellTile.Create(new Uri("/RecipePage.xaml?DefaultTitle=FromTile", UriKind.Relative), tileData, true); }
    • Updating Tiles // Find the Tile we want to update. ShellTile TileToFind = ShellTile.ActiveTiles.FirstOrDefault( x => x.NavigationUri.ToString().Contains("DefaultTitle=FromTile")); // If the Tile was found, then update the Title. if (TileToFind != null) { FlipTileData NewTileData = new FlipTileData { Title = textBoxTitle.Text }; TileToFind.Update(NewTileData); }
    • Updating the Application Tile public static void UpdateMainTile(RecipeDataGroup group) { //Get application's main tile – application tile always first item in the ActiveTiles collection //whether it is pinned or not var mainTile = ShellTile.ActiveTiles.FirstOrDefault(); IconicTileData tileData = new IconicTileData() { Count = group.RecipesCount, BackgroundColor = Color.FromArgb(255, 195, 61, 39), Title = "Contoso Cookbooks", IconImage = new Uri("ms-appx:///local/shared/shellcontent/newMedLogo.png", UriKind.RelativeOrAbsolute), SmallIconImage = new Uri("ms-appx:///local/shared/shellcontent/newSmlLogo.png", UriKind.RelativeOrAbsolute), WideContent1 = "Recent activity:", WideContent2 = "Browsed " + group.Title + " group", WideContent3 = "with total of " + group.RecipesCount + " recipes" }; mainTile.Update(tileData); }
    • Demo 2: Tile API – Create, Update, Delete
    • Updating Tiles with a Tile Schedule • Periodically updates the tile image without pushing message though • Can only update the image on the front of the tile • Updates images only from the web, not from the app local store • Sets up notification channel and binds it to a tile notification • Few limitations • Image size must be less than 150 KB (up from 80KB in WP7.1) • Download time must not exceed 45 seconds (up from 30 seconds in 7.1) • Lowest update time resolution is 60 minutes • If the schedule for an indefinite or finite number of updates fails too many times, OS will cancel it • Update recurrence can by Onetime, EveryHour, EveryDay, EveryWeek or EveryMonth 20
    • Scheduling Tile Update 21 public partial class MainPage : PhoneApplicationPage { ShellTileSchedule SampleTileSchedule = new ShellTileSchedule(); private void buttonIndefinite_Click(object sender, RoutedEventArgs e) { // Updates will happen on a fixed interval. SampleTileSchedule.Recurrence = UpdateRecurrence.Interval; // Updates will happen every hour. // Because MaxUpdateCount is not set, the schedule will run indefinitely. SampleTileSchedule.Interval = UpdateInterval.EveryHour; SampleTileSchedule.RemoteImageUri = new Uri(@"http://www.weather.gov/forecasts/graphical/images/conus/MaxT1_conus.png"); // Updates will apply to the application tile. SampleTileSchedule.Start(); } }
    • Scheduling Secondary Tile Updates 22 foreach (ShellTile TileToSchedule in ShellTile.ActiveTiles) { ShellTileSchedule mySchedule = new ShellTileSchedule(TileToSchedule); mySchedule.Interval = UpdateInterval.EveryHour; mySchedule.Recurrence = UpdateRecurrence.Interval; mySchedule.RemoteImageUri = imageURI; mySchedule.Start(); } • Can also schedule updates for secondary tiles by passing the ShellTile object into the ShellTileSchedule constructor
    • Updating Tiles From a Background Agent • In Windows Phone OS 7.0, only way of updating Live Tiles was from a Tile Schedule or from Push Notifications • Tile Schedule needs to fetch images from a web URI • Push Notifications require you to implement a backend service • To have control of shell tiles when the app is not running without using Push Notifications, a good solution is a Background Agent • Use the ShellTile API to locate and update tiles
    • Demo 3: Updating Tiles From a Background Agent
    • 3/18/2014Microsoft confidential25 Lock screen notifications on Windows Phone
    • Lock Screen on Windows Phone 7 • On Windows Phone 7, Notifications area was reserved to first party apps • Next Calendar Appointment • Icons and counts for missed calls, new email, new SMS • User could select background image • From supplied Wallpapers • From their own pictures 26 NOTIFICATIONS AREA
    • • End user can now select any app that has been enabled for lock screen notifications to show detailed status • Select any five apps to show quick status (icon and count) • For your app to be included in the notifications area, all you have to do is • Create an icon • Declare the app’s intent in the application manifest file 3/18/201427 Lock Screen on Windows Phone 8
    • • Create a 24 x 24 pixel PNG image that will be used to identify your app on the lock screen • Contain only white pixels and transparent background • Default name is LockIcon.png • Use this name and you do not have to explicitly declare it in the application manifest • If you use another name, • Edit WMAppManifest.xml using the XML editor • Change the DeviceLockImageURI element which is listed inside the Tokens element: Creating a lock screen icon 3/18/2014Microsoft confidential28 <Tokens> <PrimaryToken TokenID="PhoneApp4Token" TaskName="_default"> <TemplateFlip> … <DeviceLockImageURI>MyLockIcon.png</DeviceLockImageURI> </TemplateFlip> </PrimaryToken> </Tokens>
    • • Edit WMAppManifest.xml with the XML editor • Find the <Extensions> element. If not there, create it immediately following the <Tokens> element. • Inside the <Extensions> element, create <Extension> elements for each feature you want to support: Icon Count and/or Text <Extensions> <Extension ExtensionName="LockScreen_Notification_IconCount" ConsumerID="{111DFF24-AA15-4A96-8006-2BFF8122084F}" TaskID="_default" /> <Extension ExtensionName="LockScreen_Notification_TextField" ConsumerID="{111DFF24-AA15-4A96-8006-2BFF8122084F}" TaskID="_default" /> </Extensions> Updating the Application Manifest File 3/18/2014Microsoft confidential29
    • • Lock Screen Icon Count and Text is taken directly from your applications primary tile • Secondary tiles are not used for this feature • Information is only displayed on the lock screen if the tile contains the information • For example, a count will only be displayed if the tile displays it • Primary tile does not need to be pinned to the Start Screen for lock screen notifications to be enabled • Update Primary Tile content in the usual way • Local Shell Tiles API • Push Notifications How to Update the Icon Count and Text 3/18/2014Microsoft confidential30
    • • Simulation Dashboard allows you to display the Lock Screen on the emulator • Access the Simulation Dashboard from the Visual Studio Tools menu Testing with the Simulation Dashboard 3/18/2014Microsoft confidential31
    • Demo 4: Lock Screen Notifications
    • 3/18/2014Microsoft confidential33 Lock Screen Background
    • • End user can choose a background image from their own photos or search for an image on Bing • In addition, they can choose an app to be the background image provider • For your app to be a lock screen background provider, all you have to do is • Declare the app’s intent in the application manifest file • Write code to change the background image 3/18/201434 Lock Screen Background on Windows Phone 8
    • • Edit WMAppManifest.xml with the XML editor • Find the <Extensions> element. If not there, create it immediately following the <Tokens> element. • Inside the <Extensions> element, create an <Extension> element for LockScreen_Background <Extensions> <Extension ExtensionName="LockScreen_Background" ConsumerID="{111DFF24-AA15-4A96-8006-2BFF8122084F}" TaskID="_default" /> </Extensions> Updating the Application Manifest File 3/18/2014Microsoft confidential35
    • Write Code to Change the Lock Screen Background private async void lockHelper(Uri backgroundImageUri, string backgroundAction) { try { //If you're not the provider, this call will prompt the user for permission. //Calling RequestAccessAsync from a background agent is not allowed. var op = await LockScreenManager.RequestAccessAsync(); //Check the status to make sure we were given permission. bool isProvider = LockScreenManager.IsProvidedByCurrentApplication; if (isProvider) { //Do the update. Windows.Phone.System.UserProfile.LockScreen.SetImageUri(backgroundImageUri); System.Diagnostics.Debug.WriteLine("New current image set to {0}", backgroundImageUri.ToString()); } else { MessageBox.Show("You said no, so I can't update your background."); } } catch (System.Exception ex) { System.Diagnostics.Debug.WriteLine(ex.ToString()); } }
    • • Call to LockScreenManager.RequestAccessAsync is required • Checks if your app is already the selected lock screen background provider • If not, prompts user for permission to make your app the selected provider User Confirmation 3/18/201437 //If you're not the provider, this call will prompt the user for permission. //Calling RequestAccessAsync from a background agent is not allowed. var op = await LockScreenManager.RequestAccessAsync();
    • • To use an image that you shipped in your app, use ms-appx:/// Uri imageUri = new Uri("ms-appx:///background1.png", UriKind.RelativeOrAbsolute); LockScreen.SetImageUri(imageUri); • To use an image stored in the Local Folder, use ms-appdata:///local/shared/shellcontent • Must be in or below the /shared/shellcontent subfolder Uri imageUri = new Uri("ms-appdata:///local/shared/shellcontent/background2.png", UriKind.RelativeOrAbsolute); LockScreen.SetImageUri(imageUri); Accessing Local Images 3/18/2014Microsoft confidential38
    • Demo 5: Lock Screen Background
    • Review • Shell Tile API allows easy manipulation of tiles from within an application • Tiles can have a front and a back, and apps can have secondary tiles • Tiles and Toasts can launch into a specific page within the app • Only the user can decide to pin an apps’ primary tile to the Start Screen, not from code • App can declare in the App manifest that it can be a lock screen notification provider • User must select apps to display lock screen notifications from phone Settings • Optionally supply count and/or text – these are pulled directly from the primary tile • App can also declare that it can be a lock screen background provider • Code used to request permission from the user and to change the lock screen background
