Пуш-уведомление Android Firebase не отображается

Привет, я пытаюсь отправить push-уведомление в свое приложение, используя Firebase, и я учусь на этом уроке. http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/

когда я захожу в уведомление Firebase и отправляю уведомление, оно говорит мне, что состояние завершено, но не отправляет никаких уведомлений в мое приложение, и я не могу понять, почему .. Я точно следовал этому руководству

вот код, который я взял из учебника:

Конфиг класс

public class Config {

public static final String TOPIC_GLOBAL = "global";

public static final String REGISTRATION_COMPLETE = "registrationComplete";
public static final String PUSH_NOTIFICATION = "pushNotification";

public static final int NOTIFICATION_ID = 100;
public static final int NOTIFICATION_ID_BIG_IMAGE = 101;

public static final String SHARED_PREF = "ah_firebase";

}

MyFirebaseInstanceIDService класс

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

private static final String TAG = MyFirebaseInstanceIDService.class.getSimpleName();

@Override
public void onTokenRefresh() {
super.onTokenRefresh();
String refreshedToken = FirebaseInstanceId.getInstance().getToken();

// Saving reg id to shared preferences
storeRegIdInPref(refreshedToken);

// sending reg id to your server
sendRegistrationToServer(refreshedToken);

// Notify UI that registration has completed, so the progress indicator can be hidden.
Intent registrationComplete = new Intent(Config.REGISTRATION_COMPLETE);
registrationComplete.putExtra("token", refreshedToken);
LocalBroadcastManager.getInstance(this).sendBroadcast(registrationComplete);
}

private void sendRegistrationToServer(final String token) {
// sending gcm token to server
Log.e(TAG, "sendRegistrationToServer: " + token);
}

private void storeRegIdInPref(String token) {
SharedPreferences pref = getApplicationContext().getSharedPreferences(Config.SHARED_PREF, 0);
SharedPreferences.Editor editor = pref.edit();
editor.putString("regId", token);
editor.commit();
}

}

MyFirebaseMessagingService класс
