Google Cast Android Sender: ResultCallback pas appelé

Question

Je suis en train de travailler sur le tutoriel de l'application Google Cast Sender pour Android et je me suis retrouvé coincé quand il s'agit d'une connexion au Cast CustomReceiver.

J'utilise la mise en œuvre ConnectionCallbacks suivante:

private class ConnectionCallbacks implements GoogleApiClient.ConnectionCallbacks { 
    @Override 
    public void onConnected(Bundle bundle) { 
     Log.i(TAG, "ConnectionCallbacks.onConnected"); 

     LaunchOptions options = new LaunchOptions.Builder() 
       .setRelaunchIfRunning(false) 
       .build(); 
     Cast.CastApi 
       .launchApplication(mApiClient, getString(R.string.google_cast_key), options) 
       .setResultCallback(new ResultCallback<Cast.ApplicationConnectionResult>() { 
        @Override 
        public void onResult(Cast.ApplicationConnectionResult result) { 
         Status status = result.getStatus(); 
         if (status.isSuccess()) { 
          Log.i(TAG, "Success!!! " + result.getApplicationStatus()); 
         } else { 
          Log.e(TAG, "No success!!! " + result.getApplicationStatus()); 
         } 
        } 
       }); 
    } 

    @Override 
    public void onConnectionSuspended(int i) { 
     Log.i(TAG, "ConnectionCallbacks.onConnectionSuspended: " + i); 
    } 
} 

Et le code CustomReceiver:

<script> 

    window.castReceiverManager = cast.receiver.CastReceiverManager.getInstance(); 

    var appConfig = new cast.receiver.CastReceiverManager.Config(); 

    appConfig.statusText = 'Ready to play'; 

    // 100 minutes for testing, use default 10sec in prod by not setting this value 
    appConfig.maxInactivity = 6000; 

    window.castReceiverManager.start(); 
    console.log('Starting Receiver Manager'); 
    document.getElementById("message").innerHTML='Starting Receiver Manager'; 
</script> 

Quand je choisis mon Chromecast de la boîte de dialogue, mon application récepteur personnalisé est lancé sur le Chromecast et la app logs

11-05 22:38:00.470: I/MainActivity(8955): ConnectionCallbacks.onConnected 

Cependant, il n'appelle jamais s le onResult ou le onConnectionSuspended du ResultCallback ni le ConnectionFailedListener. Qu'est-ce que je rate?

Je résolu mon problème. Ce n'était pas l'expéditeur, c'était le receveur. Google n'indique pas qu'il est nécessaire d'enregistrer un MessageBus lors de l'utilisation de CustomReceivers. La ReceiverCode minimale pour obtenir l'expéditeur connecté au récepteur doit être:

var namespace = 'urn:x-cast:com.denis_loh.desorona' 

    window.onload = function() { 
    cast.receiver.logger.setLevelValue(0); 
    window.castReceiverManager = cast.receiver.CastReceiverManager.getInstance();  

    // Erstelle MessageBus zum Austauschen von Daten 
    window.messageBus = window.castReceiverManager.getCastMessageBus(namespace); 

    // Lege onMessage-Callback für den MessageBus fest. 
    window.messageBus.onMessage = onMessage; 

    // Starte den Receiver. 
    window.castReceiverManager.start({statusText: "Application is starting"}); 
    console.log('Receiver Manager started'); 
    }; 

    function onMessage(event) { 
    window.messageBus.send(event.senderId, event.data); 
    } 

Cependant, je ne sais pas encore, pourquoi cela est nécessaire après tout.
