Answer 2

C2DMBroadcastReceiver.java

if (Constants.RECEIVED_REGISTRATION_ID_FROM_GOOGLE.equals(intent.getAction())) { 
//here you can get registration id 
    final String registrationId = intent 
        .getStringExtra("registration_id"); 
/*your code*/ 
} 

và sau đó gọi phương pháp registerIdWithC2DMService(registrationId) từ RegistrationIDRegistrar lớp học.
