MessageBody d'affichage de la notification Firebase comme Toast

Question

Je reçois une exception d'exécution sur l'affichage d'un message Toast

java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() 

Je veux afficher le corps du message comme un message Toast lorsque l'utilisateur reçoit une notification push de n'importe où dans l'application.

Toute aide?

public class MyAppFirebaseMessagingService extends FirebaseMessagingService { 

    private static final String TAG = "FCM Service"; 

    @Override 
    public void onMessageReceived(RemoteMessage remoteMessage) { 
       if (remoteMessage.getNotification() != null) { 
      if (AppConfig.SYSTEM_WIDE_DEBUG) { 
       Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody()); 
      } 

      sendNotification(remoteMessage.getNotification().getBody()); 
     } 

    } 

    private void sendNotification(String messageBody) { 
     Toast.makeText(getApplicationContext(),messageBody,Toast.LENGTH_LONG).show(); 

     Intent intent = new Intent(this, HomeActivity.class); 
     intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
     PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent, PendingIntent.FLAG_ONE_SHOT); 

     Uri defaultSoundUri = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.pushnotify); 
     NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) 
       .setSmallIcon(R.mipmap.ic_launcher) 
       .setContentTitle("My APP") 
       .setContentText(messageBody) 
       .setAutoCancel(true) 
       .setSound(defaultSoundUri) 
       .setContentIntent(pendingIntent); 

     NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 

     notificationManager.notify(0 /* ID of notification */, notificationBuilder.build()); 
    } 
}

Si vous voulez afficher Toast.Vous devez exécuter sur le thread UI;

Exemple:

Handler handler = new Handler(Looper.getMainLooper()); 
handler.post(new Runnable() { 
    public void run() { 
     Toast.makeText(getApplicationContext(),Toast.LENGTH_SHORT).show(); 
    } 
});
