[9] use of the injection framework roboguice: (your first injected service and broadcastreceiver)

In the previous article, we briefly introduced the use of roboguice ([8] injection framework roboguice: (your first injected fragment). Let's take a look at the service) and broadcast receiver Injection

(1): Like Robo * Activities, roboservices and robointentservices automatically accept injection through roboguice.

The following is an example of Android service injected with roboguice:

public class MyService extends RoboService {   @Inject ComputeFooModule computeFooModule;   public void onCreate() {        super.onCreate();        //All injections are available from here :        computeFooModule.setUp();   }   public int onStartCommand(Intent intent, int flags, int startId) {        computeFooModule.computeFoo();        return super.onStartCommand();   }}

Roboguice also provides the robointentservice as the injection base class for intentservice.

(2) broadcast receiver Injection

With roboguice, Android broadcast receiver can also accept injection.

public class MyBroadcastReceiver extends BroadcastReceiver {   @Inject ComputeFooModule computeFooModule;    protected void handleReceive(Context context, Intent intent) {        //All injections are available from here :        computeFooModule.setUp().computeFoo();        ...   }}

(3) [note] In roboguice, all broadcast recipients can accept injection throughout the application. This means that even contextsingleton will be converted to singleton here.
