The above accepted answer did not worked for me. But a small modification did the trick. This works quite well with Messenger based communication.

public class BoundService extends Service {

    public static final int TEST = 100;
    private final Messenger messenger = new Messenger(new MessageHandler());

    class MessageHandler extends Handler {
        @Override
        public void handleMessage(Message msg) {

            String callerId = getApplicationContext().getPackageManager().getNameForUid(msg.sendingUid);
            Toast.makeText(getApplicationContext(), "Calling App: " + callerId, Toast.LENGTH_SHORT).show();

            switch (msg.what) {
                case TEST:
                    Log.e("BoundService", "Test message successfully received.")
                    break;
                default:
                    super.handleMessage(msg);
            }
        }
    }

    @Override
    public IBinder onBind(Intent intent) {
        return messenger.getBinder();
    }
}

From the above answer, you only need to change from Binder.getCallingUid() to msg.sendingUid
