Live Tiles & Push Notifications
29

27. Windows Phone 7
Live Tiles
Live Tiles allow content on a
tile to be updated and
changed remotely to signifly
a change in the backend
application
30

28. Windows Phone 7
Creating a tile
ShellTile.Create(new Uri("/MainPage.xaml", UriKind.Relative),
new StandardTileData(){
BackgroundImage = new Uri("isostore:/Shared/ShellContent/image.png",
UriKind.Absolute),
Title = "Sample"});
Tiles are recto and verso
There are also some additional properties that you can use in addition to the basic ones:
BackContent - used to display a string onthe back of the tile. The tile itself will automatically rotate betwen the
base and secondary content.
BackTitle - the title to be displayed on the back of the tile.
Count - the count displayed in the corner of the tile. Only displayed on the front side of the tile.
BackBackgroundImage - the background image displayed on the back of the tile.
31

29. Windows Phone 7
Update/Deleting tiles
Tiles can expire or need updating
Enumerate the tiles associated with the application, accessible
through the ShellTile.ActiveTiles IEnumerable:
foreach (ShellTile tile in ShellTile.ActiveTiles){
Debug.WriteLine(tile.NavigationUri.ToString());
}
For each shell tile, we can either Update it (and pass a new
instance of StandardTileData with updated content) or Delete it.
32

30. Windows Phone 7
Push Notifications
3 Types of Push
Notifications
Toast Notifications
Tile Notifications
Raw Notifications
33

31. Windows Phone 7
Push Notifications : Toast Notifications
Title. A boldface string that displays immediately after the application icon. This is defined as
the Text1 property in the XML schema.
Content. A non-boldface string that displays immediately after the Title. This is defined as the
Text2 property in the XML schema.
Parameter. A parameter value that is not displayed but passed to your application if the user
taps on the toast. This parameter can indicate what page the application should launch to. It
can also contain name-value pairs to pass to the application. This is defined as the Param
property in the XML schema.

Background Agents
40

38. Windows Phone 7
What are background agents?
 Background Agents are a seperate project from the
application you are creating.
 They are instantiated when the application isn’t in an
active state. When the application is in an active state,
they don’t run.
 Maximum of 18 simultaneous agents.
 Background Agents are desactivated 14 days if they are
never used.
41

39. Windows Phone 7
What can/can’t you do with Background Agents
Allowed Not Allowed
 Tiles  Interact with UI
 Toast  XNA Libraries
 Location Services  Microphone & Camera
 Connectivity  Sensors
 Access to  Play audio without using
IsolatedStorage the appropriate APIs for
 Sockets background sound
 Most APIs
42

40. Windows Phone 7
Background Agents
 Background Transfer Service
 Background Audio
 Background Agents
 Periodic
 On Idle
 Alarms and Reminders
43

41. Windows Phone 7
Background Agents
Background Agents in Mango take the form of a separate assembly, which gets linked
in your WMAppManifest.xml
44

42. Windows Phone 7
Background Agents
Background Transfer Service
45

43. Windows Phone 7
Background Agents : Background Transfer Service
 Start in foreground, complete in background, even if
app is closed
 Queue (of 5) persists across reboots
 Single service for many apps, FIFO
 Download ~20 MB ( > over Wi-Fi)
 Upload Size ~4 MB (limit to come)
 Transfers to Isolated Storage 46

ScheduledTask Agent
48

46. Windows Phone 7
Background Agents : ScheduledTask Agent
It is possible to have in Windows Phone 7 to execute code
as a planned tack.
There are two types of scheduled tasks therefore one class
that from ScheduledTask for each of these types :
PeriodicTask and ResourceIntensiveTask
49

47. Windows Phone 7
Background Agents : ScheduledTask Agent
Limitations:
 Memory 5 Mo
 Expiration : 2 Weeks
 Restrained acces to APIs
 User can desactivate them
PeriodicTask :
 Every 30 minutes (+/-) for 15 seconds
 Can be dismissed if two many background agents are active
ResourceIntensiveTask
 Runs for 10 minutes
 Only runs if the phone is plugged in
 If the phone is connected to Wifi or PC
 If the phone is 90% Charged
 If absolutely no application is running on the phone
50

48. Windows Phone 7
Background Agents : ScheduledTask Agent
Microsoft.Phone.Scheduler.PeriodicTask
PeriodicTask periodicTask = new PeriodicTask("TaskUniqueNameInApp");
periodicTask.Description = "My Periodic Task Description";
periodicTask.ExpirationTime = DateTime.Now.AddDays(10);
ScheduledActionService.Add(periodicTask);
Microsoft.Phone.Scheduler.ResourceIntensiveTask
ResourceIntensiveTask intensiveTask new ResourceIntensiveTask("TaskUniqueNameInApp");
intensiveTask.Description = "My Intensive Task Description";
intensiveTask.ExpirationTime = DateTime.Now.AddDays(10);
ScheduledActionService.Add(intensiveTask)
51

49. Windows Phone 7
Background Agents : ScheduledTask Agent
Then create a class that inherits of ScheduledTaskAgent and override OnInvoke and OnCancel
public class TaskScheduler : ScheduledTaskAgent
{
protected override void OnInvoke(ScheduledTask task)
{
if (task is PeriodicTask)
{ }
else //is ResourceIntensiveTask
{ }
NotifyComplete();
}
}

Sockets
54

52. Windows Phone 7
Sockets
Windows Phone provides the programming interface needed to create and use TCP and UDP sockets. You can select
which type of socket to use based on your application’s needs.
55

53. Windows Phone 7
Sockets
using System.Net.Sockets;
public string Connect(string hostName, int portNumber) {
DnsEndPoint hostEntry = new DnsEndPoint(hostName, portNumber);
_socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
socketAsyncEventArgs socketEventArg = new SocketAsyncEventArgs();
socketEventArg.RemoteEndPoint = hostEntry;
socketEventArg.Completed += new EventHandler<SocketAsyncEventArgs>( delegate(object s, SocketAsyncEventArgs e)
{
result = e.SocketError.ToString();
_clientDone.Set(); });
_clientDone.Reset();
_socket.ConnectAsync(socketEventArg);
_clientDone.WaitOne(TIMEOUT_MILLISECONDS);
});
return result;
}
56

54. Windows Phone 7
Contacts/Calendar
57

55. Windows Phone 7
Contacts/Calendar
In Windows Phone, you can now access the user information asynchrously, and even better you can query them with
Linq !!!
using Microsoft.Phone.UserData;
Get contacts:
private void ButtonContacts_Click(object sender, RoutedEventArgs e) {
Contacts cons = new Contacts();
//Identify the method that runs after the asynchronous search completes.
cons.SearchCompleted += new EventHandler<ContactsSearchEventArgs>(Contacts_SearchCompleted);
//Start the asynchronous search.
cons.SearchAsync(String.Empty, FilterKind.None, "Contacts Test #1");
}
void Contacts_SearchCompleted(object sender, ContactsSearchEventArgs e) {
//Do something with the results.
MessageBox.Show(e.Results.Count().ToString());
}
58

56. Windows Phone 7
Contacts/Calendar
using Microsoft.Phone.UserData;
Get appoinments using Linq:
void Appointments_SearchCompleted(object sender, AppointmentsSearchEventArgs e)
{
try
{
AppointmentResultsDataLINQ.DataContext = from Appointment appt in e.Results
where appt.IsAllDayEvent == false
select appt;
}
catch (System.Exception)
{
//No results
}
}

Media
60

58. Windows Phone 7
Media
You can use the following features to consume media in a Windows Phone application:
 Use the MediaPlayerLauncher class for Windows Phone to embed audio or video using the device media player. Cf.
Launchers and Choosers chapter
 Use the Silverlight MediaElement API to embed audio or video using a more customizable interface.
 MediaElement for Windows Phone has a few differences than MediaElement for the desktop.
 Add sound effects using XNA Game Studio.
 Use the MediaStreamSource class for adaptive streaming solutions.
 Use Microsoft.Phone.BackgroundAudio to create a media application that will continue playing audio when another
application is in the foreground. Cf. background agents chapter
61

59. Windows Phone 7
Media : MediaElement
<MediaElement Name="mediaElement1" Source="http://mschannel9.vo.msecnd.net/o9/mix/09/wmv/key01.wmv" AutoPlay="True"/>
mediaElement1.Play();
mediaElement1.Pause();
mediaElement1.Stop();

60. Windows Phone 7
Media : Integration with the music hub
63

61. Windows Phone 7
Media : Integration with the music hub
Your Music + Videos Hub application must conform to the Application Certification
Requirements for Windows Phone to integrate with the Music + Videos Hub.
Tiles that are displayed in the Music + Videos Hub must conform to additional iconography rules:
 You must include your application title or logo on each Tile.
 The now playing Tile must be 358 pixels x 358 pixels. The file size must be 75 KB or less.
 Other tiles must be 173 pixels x 173 pixels in size.
 The Title property of the MediaHistoryItem class must be set to text that represents the content, such as a
station name or video title.
To help avoid confusion for users, Hub Tiles should not contain album art unless the album plays when the Hub
Tile is pressed.
If your application plays a stream, the Hub Tile graphic should describe the stream that is being played.
This is not a certification requirement, it is a good practice.
64

62. Windows Phone 7
Media : Integration with the music hub
Updating the 'now playing' Tile of the 'history' List
MediaHistoryItem mediaHistoryItem = new MediaHistoryItem();
//<hubTileImageStream> must be a valid ImageStream.
mediaHistoryItem.ImageStream = <hubTileImageStream>;
mediaHistoryItem.Source = "";
mediaHistoryItem.Title = "NowPlaying";
mediaHistoryItem.PlayerContext.Add("keyString", "Song Name");
MediaHistory.Instance.NowPlaying = mediaHistoryItem;

63. Windows Phone 7
Camera API
66

64. Windows Phone 7
Application Lifecycle Pre-Mango
Windows Phone supports programmatic access to the camera on a device, offering a rich
set of APIs for developers to create their applications.
Some features include:
 Creating a camera application with a viewfinder and capturing still photos
 Providing real-time access to raw frames from the camera
 Adjusting the resolution of the captured photo
 Implementing functionality such as focus and flash
 Detecting and querying the device camera capabilities such as flash
 Accessing the camera hardware shutter button for capturing photos and triggering auto-focus
67

65. Windows Phone 7
Camera API
68

66. Windows Phone 7
Camera API
To use a camera in your Windows Phone application, you must add the
camera capability (ID_CAP_ISV_CAMERA) to the application manifest file.
<Capability Name="ID_CAP_ISV_CAMERA"/>
<Capability Name="ID_HW_FRONTCAMERA"/>
