Cloud to device messaging…

HaIt allows third-party application servers to send lightweight messages to their Android applications

C2DM makes no guarantees about delivery or the order of messages

An application on an Android device doesn’t need to be running to receive messages

Cloud to device messaging…

It does not provide any built-in user interface or other handling for message data

It requires devices running Android 2.2 or higher that also have the Market application installed

It uses an existing connection for Google services

AC2DM Lifecycle1. Register device for

Push2. App server send

message

3. Device receives message

4. Unregister device

Build your app Requesting a Registration ID

C2DMessaging.register(this, "sender@gmail.com");

Build your app Receiving the Registration ID

public class C2DMReceiver extends C2DMBaseReceiver {

public C2DMReceiver() {super("sender@gmail.com");

}

@Overridepublic void onRegistered(Context context, String registrationId)

{ // TODO send registration ID to the app server

}...

}

Build your app Receiving Messages

public class C2DMReceiver extends C2DMBaseReceiver {...

@Overrideprotected void onMessage(Context context, Intent intent) {

String payload = intent.getStringExtra("payload");// TODO handle the message

}}
