Android Mobile/Wear App onMessageReceived Called Multiple Times for One Message

I've got a basic Android Wear app that successfully uses the Wearable Data Layer to send and receive messages between the mobile device and Wear.

However, any time I send a message (from Mobile or Wear device) the other end receives it multiple times (like anywhere from 5-17). Why is it not just received once? As far as I can tell it's only sending once.

After successfully connecting, here is my code to Send Message (same on both ends):

private void sendMsgToWear(final String strMsg){

    new AsyncTask<Void, Void, List<Node>>(){

        @Override
        protected List<Node> doInBackground(Void... params) {
            return getNodes();
        }

        @Override
        protected void onPostExecute(List<Node> nodeList) {
            for(Node node : nodeList) {
                Log.v("DEVELOPER", "......Phone: Sending Msg: " + strMsg + " to node:  " + node.getId());

                PendingResult<MessageApi.SendMessageResult> result = Wearable.MessageApi.sendMessage(
                        mGoogleApiClient,
                        node.getId(),
                        strMsg,
                        null
                );

                result.setResultCallback(new ResultCallback<MessageApi.SendMessageResult>() {
                    @Override
                    public void onResult(MessageApi.SendMessageResult sendMessageResult) {
                        Log.v("DEVELOPER", "......Phone: " + sendMessageResult.getStatus().getStatusMessage());
                    }
                });
            }
        }
    }.execute();


}

private List<Node> getNodes() {
    List<Node> nodes = new ArrayList<Node>();
    NodeApi.GetConnectedNodesResult rawNodes =
            Wearable.NodeApi.getConnectedNodes(mGoogleApiClient).await();
    for (Node node : rawNodes.getNodes()) {
        nodes.add(node);
        nodeID = node.getId();
    }
    return nodes;
}

And here is how I Receive on my activity that implements MessageApi.MessageListener:

@Override
public void onMessageReceived(MessageEvent messageEvent) {

    Log.d("DEVELOPER", "......Wear: successfully received phone to wear communication!");


}

My output on send side looks like:

07-11 10:54:57.646  26920-28711/com.wearTest.message V/DEVELOPER﹕ ......Phone: Sending Msg: testMessage to node:  6ecc099a-60f8-4c3d-90fe-fa2f248c6bf7
07-11 10:54:57.666  26920-26920/com.wearTest.message V/DEVELOPER﹕ ......Phone: null

And the receive side logs:

Thanks in advance!

The MessageApi should be working fine. Just be careful to call addListener() only once, or you will get notified multiple times.

Alternatively, add matching removeListener() calls (for example in onResume() / onPause()).
