Android : GCM intent services OnRegistered method is not getting called

In the log I am getting this message.

V/GCMBroadcastReceiver(30668): onReceive: com.google.android.c2dm.intent.REGISTRATION

08-07 11:12:59.096: V/GCMBroadcastReceiver(30668): GCM IntentService class: com.example.notifications.GCMIntentService

08-07 11:12:59.096: V/GCMBaseIntentService(30668): Acquiring wakelock

But OnRegistered method is not been invoked ( Running app in my MotoG device ). Below is the manifest.xml coding.

And my MainActivitiy.java file

 public static final String SENDER_ID = "xxxxxxxxx";
    GCMRegistrar.checkDevice(MainActivity.this);
    GCMRegistrar.checkManifest(MainActivity.this);
    ChannelUri = GCMRegistrar.getRegistrationId(getApplicationContext());
    if(ChannelUri.equals(""))
    {
    GCMRegistrar.register(getApplicationContext(), SENDER_ID);
    }
    else
    {
    Toast.makeText(getApplicationContext(), "Already Registered", Toast.LENGTH_SHORT).show();
    }

GCMIntentService.java

public class GCMIntentService extends GCMBaseIntentService {

public static String sRegistrationId;

protected GCMIntentService() {
super(MainActivity.SENDER_ID);
}


public static String getRegistrationId()
{
return sRegistrationId;
}



@Override
protected void onError(Context arg0, String arg1) {
Log.e("Registration", "Got an error!");
Log.e("Registration", arg0.toString() + arg1.toString());

}

@Override
protected void onMessage(Context arg0, Intent intent) {

Log.i("Registration", "Got a message!");
Log.i("Registration", arg0.toString() + " " + intent.toString());


}

@Override

sRegistrationId = arg1;
Log.i("Registration", "Just registered!");
Log.i("Registration", arg0.toString() + arg1.toString());
}

@Override

// TODO Auto-generated method stub

}
}
