磨损addListener的onDataChanged没有被调用

Question

I'm encountering a very weird scenario. I implemented both WearableListenerService and Wearable.DataApi.addListener on my wear device, and I am periodically sending data updates from my phone. The WearableListenerService is properly getting onDataChanged callbacks, but my listener in the main activity isn't..

This is my setup for the activity:

onStart() {
    super.onStart();
    googleApiClient.connect();
}

onStop() {
    googleApiClient.disconnect();
    Wearable.DataApi.removeListener(googleApiClient, this);
    super.onStop();
}

onConnected() {
    Wearable.DataApi.addListener(googleApiClient, this);
}

onDataChanged() {
    // never gets called
}

I can post more code, but above is the general gist. On the other hand, my WearableListenerService is properly declared in the AndroidManifest , and simply prints out logs when it receives onDataChanged .

Is there anything obvious I'm missing here?

Answer 1

For this you will have to implement one of the following interfaces in your activity:

• DataApi.DataListener
• MessageApi.MessageListener
• NodeApi.NodeListener

See 'With a Listener Activity' part of this android developer documentation.
