Windows Phone allows apps to display live tiles and lock screen notifications. The Shell Tile API allows apps to create, update, and delete tiles from within the app. Tiles can display different content on the front and back and launch to specific pages. Apps can also update tiles and send notifications using background agents and push notifications. The app manifest declares support for lock screen notifications and backgrounds, but the user must select the app in settings. Notification text and counts are pulled from the primary tile. Apps can request permission to set the lock screen background image.

- 3. Live Tiles • Windows phone has the unique ability to provide the end user glanceableaccess 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
- 4. Live Tiles • 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 4
- 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 5
- 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 6 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
- 7. Flip Tile Template • Flips from front to back • Small size does not flip • Medium size is the same as the WP7.1 tile template 8/16/2014 7
- 8. Cycle Tile Template • Cycles between from 1 to 9 images • Small tile does not cycle 8/16/2014 8
- 9. Iconic Tile Template • Displays a small image in the center of the Tile and is designed to reflect Windows Phone design principles 8/16/2014 9
- 10. 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 createa 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
- 11. 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 8/16/2014 11
- 12. 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 8/16/2014 12
- 14. Creating and Updating Tiles with the Local Tile API • Localtileupdates(these are*not*push) • Fullcontrolofallproperties whenyourapp isintheforeground orbackground • ManageSecondaryTiles • Create/Update/Delete • Launchesdirectly topage/experience
- 15. 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); }
- 16. 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); }
- 17. 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); }
- 19. 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 19
- 20. Scheduling Tile Update 20 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(); } }
- 21. Scheduling Secondary Tile Updates 21 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
- 22. Updating Tiles From a Background Agent • In Windows Phone OS 7.0, only way of updatingLive 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

- 38. Summary • 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
