Ich möchte eine Nachricht an zwei verschiedene Android Smart-Watches senden. Auf der mobilen Seite wird die Wearable.MessageApi.sendMessage aufgerufen und die sendMessageResult.getStatus().isSuccess() ist wahr, so sollte das Senden der Nachricht funktionieren. Das Problem ist jetzt, dass die onMessageReceived Methode der MyWearableListenerService nie eine Nachricht empfängt. Was mache ich falsch? Dies ist der Code, den ich verwende:Nachrichten an ein Android Wearable senden
MainActivity der Android App.
der linken/rechten Methoden sind das Senden der Nachrichten
