Relationship to Windows 8
• Windows Phone 8 both is and is not a Windows 8 Phone
– A first step on the path to convergence…
• UI
– Common Windows Design language (Win as One!)
– Use XAML/.NET, but with different XAML dialects and controls
– No “1st class” HTML/JavaScript app framework (though frameworks like PhoneGap / Cordova are available)
• Shared Windows 8 Technologies
– Common Kernel
– Related .NET runtimes
– Windows Runtime and Windows Phone Runtime have significant overlap
– IE10
• App Platform Differences
– App startup, app lifecycle, UI declaration, navigation, some device access, tiles/toasts/notifications
• Windows Store (8) Account is not a Windows Phone (7/8) Store Account
– Separate fees

WP7 Compatibility
• Windows Phone 8 is 99.9% compatible with WP7
• If not recompiled, WP7 apps run in “quirks mode”
• If recompiled, WP7 apps run without “quirks”
• Note - WP8 Apps are “compiled in the cloud”

XAML Application Structure
Application XAP File (Zip)

Manifest File Other Content (Binaries, Resources, Pages, etc)
• Display Name
• Start Page Application Object
• App Icon
• Supported Resolutions • System.Windows.Phone.Application PhoneApplicationFrame
• Responsible for initialization &
• Default Tile Title & Images lifetime event support • App‟s RootVisual
• Runtime Capabilities • App Startup sequence concludes • Coordinates page-to-page
• Hardware Requirements with setting the RootVisual element navigation
• Packaging Details • Journal of pages that are
• Phone Integration Settings visited


Pages & Navigation
• Primary container for app content
• Support Portrait or Landscape orientations – pages
can be locked to a particular orientation
• App interaction drives navigation between pages
• Page visits are maintained in a “backstack”
• The required hardware “Back” button is Portrait (Default)
automatically tied into page navigation

Landscape


Pages & Navigation
Orientation
Supported Orientations: SupportedOrientations – Portrait | Landscape | PortraitOrLandscape
Orientation Change: OrientationChanged += (sender, args) => { var newOrientation = args.Orientation; };

Navigation
Specific Page: NavigationService.Navigate(new Uri("/DetailPage.xaml?ID=" + itemId, UriKind.Relative));
• URI to the XAML file for the page to be created is identified
• URIs must be Relative, it must be specified.
• Arguments provided as 1-n QueryString params.
• Can tap into UriMapping
Leading „/‟ character & UriKind.Relative

Backstack Navigation: if (NavigationService.CanGoBack) NavigationService.GoBack();
NOTE: The Windows Phone API supports managing the backstack through the NavigationService.RemoveBackEntry()

Overridable protected override void OnNavigatingFrom(NavigatingCancelEventArgs e)
Navigation Handler protected override void OnNavigatedFrom(NavigationEventArgs e)

Important Windows Phone Content Controls
• LongListSelector
– Recommended over ListBox – better performance and virtualization support
– Optional List Header & Footer, Custom Grouping, Jumplist UI
• Pivot
– Present different sets of related items on a single page with horizontal wraparound sliding
– Panels are all the same width
• Panorama
– Present items conceptually related to each other on a single page with horizontal wraparound
sliding
– Panels can be individually sized
– Optionally set a background image

Application Bar
• Provide Command Bar and Command Menu functionality
• Always resides alongside the hardware buttons
• Up to 4 buttons, recommended up to 5 menu items
• App bar elements are NOT visual elements – they cannot participate in
data binding, and cannot be referenced directly by control-name in code!

Data Storage Options
• State Dictionaries
– Easy-to-access in-memory storage of limited key-value data during the lifetime
of the application instance
• File Storage APIs
– Isolated Storage - compatible with previous versions of Windows Phone (and
Silverlight), wrapper layer on top of newer storage API
– WinRT ApplicationData - new implementation of StorageFile-based data
storage, asynchronous only
• Local Database
– Using LINQ-to-SQL to store and retrieve data in a SQL Server CE database file
– Using other abstractions over local storage (SQLite, Sterling, etc.)


Page State
• Exposed as State property on the PhoneApplicationPage object
• IDictionary<String, Object>
• Objects must be serializable
• 2MB max per page, 4MB max per app.
• Only available:
– Within/after OnNavigatedTo
– Within/before OnNavigatedFrom
• Data stored in-memory and flushed with app instance
• Primarily used to store on-page control state


Application State
• Exposed as PhoneApplicationService.Current.State
• IDictionary<String, Object>
• Objects must be serializable
• Storage size limited, but not published
• Only available:
– Within or after the application‟s Activated event
– Within or before the application‟s Deactivated event
• Data stored in-memory and flushed with app instance
• Useful for app-wide per-session data, data too big for query strings,
saving state for use in Chooser success events

State Storage
Page State
State[“Key"] = value;

if (State.ContainsKey(“Key"))
{
value = State[“Key"];
}

Application State
PhoneApplicationService.Current.State[“Key"] = value;

if (PhoneApplicationService.Current.State.ContainsKey("Key"))
{
value = PhoneApplicationService.Current.State["Key"];
}


Isolated Storage API (Legacy WP7)
• Scoped to the Application
• Capacity limited only by device‟s available storage
• Storage is freed upon uninstallation
• IsolatedStorageSettings
– Data must be serializable
– IDictionary<String, Object>
– IsolatedStorageSettings.ApplicationSettings
– Written to __ApplicationSettings file
• IsolatedStorageFile
– Stream-based access to files and folders


Isolated Storage
Application Settings
IsolatedStorageSettings.ApplicationSettings["Key"] = value;

if (IsolatedStorageSettings.ApplicationSettings.Contains(“Key"))
{
value = IsolatedStorageSettings.ApplicationSettings[“Key"];
}

Files
var store = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream stream = store.OpenFile(…);
store.CreateDirectory(…); Typical File IO
store.CreateFile(…); Operations
Etc.


WinRT ApplicationData API
• Asynchronous API for interacting with Files and Folders
• Only LocalFolder is usable in WP8
– LocalSettings, RoamingSettings, RoamingFolder, TemporaryFolder will throw
exceptions if used.
– SetVersion is also not implemented in WP8
• Isolated Storage and ApplicationData APIs both write to the same
location


WinRT StorageFile
var localFolder = ApplicationData.Current.LocalFolder;

var storageFile = await localFolder.CreateFileAsync(“FileName.txt",
CreationCollisionOption.ReplaceExisting);
using (var writer = new StreamWriter(await storageFile.OpenStreamForWriteAsync()))
{
// Write file contents
}

var storageFile = await localFolder.GetFileAsync("FileName.txt");
using (var reader = new StreamReader(await storageFile.OpenStreamForReadAsync()))
{
// Process file contents
}

Intra-Application Interactions


Live Tiles
• 3 Templates: Flip, Iconic, Cycle
• Windows Phone supports creating multiple tiles for an app (secondary
tiles)
– Tiles include a Navigation Uri with query params for deep linking
• Tiles can be updated directly (must use the same template)
• Tiles can also be updated via scheduled updates, background tasks, or
through push notifications


Flip Template
• Image
– Wide image is 691 x 336
– Medium image is 336 x 336
– Small image is 159 x 159
• Title & Back Title
– Wide title is ~39 chars
– Medium title is ~19 chars
• Back Content
– Medium text is 3 lines ~13 chars ea.
– Wide text is 3 lines ~27 chars ea.
• Count: 0-99. If zero, it is not shown

Iconic Template
• Image
– Small & Wide icon are 110 x 110 max
• Best is 130 x 202
– Medium icon is 202 x 202 max
• Best is 70 x 110
• Title
• BackgroundColor is an ARGB color – Medium title is ~19 chars
• If A = 255, color is used • Content
• Otherwise, theme color is used – Wide text is 3 lines @ ~33 chars ea.


Cyclic Template
• Images
– Up to 9 images
– Wide images are 691 x 336
– Medium images are centered to
show 336 x 336
– Small image is 159 x 159
• Title
– Medium title is ~19 chars
• Count
– 0-99. If zero, it is not shown.


Updating Primary Tiles & Creating Secondary Tiles
var tileData = new (FlipTileData | IconicTileData | CyclicTileData)
{
// Set Tile Properties according to the tile type
Title = "Tile Title",
// etc.
}; The Primary Application tile is ALWAYS
the first in the list (visible or not) and
// Update Primary Tile cannot be deleted.
var firstTile = ShellTile.ActiveTiles.First();
firstTile.Update(tileData);
Tile updates must use the same type of
template as was used to create the tile.
// Secondary Tile
var uri = new Uri("/DeepLinkPage.xaml?id=data&unique=somethingunique", UriKind.Relative);
ShellTile.Create(uri, tileData, true);
Secondary tiles‟ navigation targets MUST
be unique or an exception will be thrown.

Customizing Keyboard Behavior
• Configure the Software Input Panel (SIP) to display keys appropriate to
the purpose of the input being collected.
Phone Number URL

Text & Chat
Digits Street Address Email


Scoping Your SIP

InputScope values are from the
<TextBox InputScope="TelephoneNumber"/>
InputScopeNameValue enumeration.

Illustrated description of keyboard options and special keys„ functions:
http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh393998(v=vs.105).aspx


Hardware and Sensors
• Location & Motion Sensors
– 2 Largely Parallel APIs
– Windows Phone Runtime API Windows.Devices
– .NET API in Microsoft.Devices
• Consider for code reuse if targeting both WP7 & WP8

• Restricted behavior when the app is Idle & in Background Agents


Location
// Requires ID_CAP_LOCATION & user Opt-In notification (PII)
var geoLocator = new Windows.Devices.Geolocation.Geolocator(); Replaces GeoCoordinateWatcher
geoLocator.MovementThreshold = 10; from System.Device.Location
geoLocator.DesiredAccuracy = PositionAccuracy.High;

// Single-shot
Geoposition position = await geoLocator.GetGeopositionAsync();

// Continuous
geoLocator.PositionChanged += (geolocator, args) =>
{
Dispatcher.BeginInvoke(() => When handling events, be sure
{ to marshall to the UI thread
Geocoordinate coordinate = args.Position.Coordinate;
Map.Center = coordinate.ToGeoCoordinate();
});
};

Note – The Bing Maps control is being deprecated for the phone. The Nokia map control is now part of the Phone SDK – Microsoft.Phone.Map
(Using the Map control requires setting the ID_CAP_MAP capability in the Manifest.)


Sensors
• Sensors are available through WinRT Windows.Devices.Sensors namespace
• Requires setting the ID_CAP_SENSORS capability in the Manifest
• Sensors – Windows.Devices.Sensors (7.1 API available in Microsoft.Devices.Sensors)
– <SensorName>.GetDefault()
– <Instance>.ReportInterval (Must be set to non-zero to start event-based readings.)
– <Instance>.ReadingChanged event
– <Instance>.GetCurrentReading()

Compass compass = Compass.GetDefault();
if (compass != null)
{
compass.ReportInterval = _compass.MinimumReportInterval; // Set up for reading by setting to nonzero
compass.ReadingChanged += CompassReadingChangedEventHandler;
CompassReading reading = compass.GetCurrentReading();
// reading.HeadingMagneticNorth, reading.HeadingTrueNorth
}


Camera APIs
• External
– CameraCaptureTask (Chooser) – External to the app
• In-App
– Requires setting the ID_CAP_ISV_CAMERA capability in the Manifest
– PhotoCamera – capture photos/stream videos
– PhotoCaptureDevice/AudioVideoCaptureDevice – advanced
• Lenses
– Custom camera apps that can be accessed from the OS Camera app
– Identified in manifest


Windows Phone 8 Camera Options
_cameraTask = new CameraCaptureTask();
_cameraTask.Completed += (o, e) => Note: With “Choosers”, you must
{ declare the instance as a field and
if (e.TaskResult == TaskResult.OK)
hook the event in the constructor to
{
photoImage.Source(BitmapImage(new Uri(e.OriginalFileName))); properly support suspend/tombstone.
}
}
_cameraTask.Show();

PhotoCamera camera; <Rectangle Width="320" Height="240“
camera = new PhotoCamera(); HorizontalAlignment="Left" >
viewFinderBrush.SetSource(camera); <Rectangle.Fill>
camera.CaptureImage(); <VideoBrush x:Name="viewfinderBrush" />
camera.CaptureImageAvailable += (o, e) => </Rectangle.Fill>
{ </Rectangle>
... (e.ImageStream)
}
Be sure to call Dispose on the camera so
camera.Dispose(); other parts of the app can access the device.
