Android Wear Message API unknown error code 4004

Question

I have the following block of code to sent a message to my device, but the message is not getting sent... I do not have any idea why...

Here is the code in which I build my GoogleApiClient:

mClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(new ConnectionCallbacks() {
                @Override
                public void onConnected(Bundle bundle) {
                    Log.d("dirk", "Google API Client connected");
                    sendMessage();
                }

                @Override
                public void onConnectionSuspended(int cause) {
                    Log.d("dirk", "Google API Client disconnected, cause: " + cause);
                    mConnected = false;
                    mConnecting = false;
                    // TODO handle disconnect
                }
            })
            .addOnConnectionFailedListener(new OnConnectionFailedListener() {
                @Override
                public void onConnectionFailed(ConnectionResult result) {
                    Log.d("dirk", "Google API Client connection failed, reason: " + result);
                    mConnected = false;
                    mConnecting = false;
                    // TODO handle connection failure
                }
            })
            .addApi(Wearable.API)
            .build();

And here is my code that is getting called from the sendMessage method:

Wearable.MessageApi.sendMessage(getClient(), nodeId, PATH, null).setResultCallback(new ResultCallback<SendMessageResult>() {
        @Override
        public void onResult(SendMessageResult sendMessageResult) {
            if (!sendMessageResult.getStatus().isSuccess()) {
                Log.d("dirk", "message could not be sent: " + sendMessageResult.getStatus().toString());
                Log.d("dirk", "Client connected: " + getClient().isConnected());
                // TODO show communication error
            }
        }
    });

The logging is here:

Google API Client connected
message could not be sent: Status{statusCode=unknown status code: 4004, resolution=null}
Client connected: true

So all conditions seem to be fine, but the unknown error code 4004 cannot be resolved (at least I did not find anything wrong so far). Anyone an idea what could be the reason of this?

Answer 1

I've found a documentation that supports my previous assumptions from comment above. Please take a look at WearableStatusCodes class - it contains status codes used in WearableApi method results. https://developer.android.com/reference/com/google/android/gms/wearable/WearableStatusCodes.html#INVALID_TARGET_NODE

So this error is no longer "unknown":) - 4004 is a code for INVALID_TARGET_NODE.
Please check what value you pass in nodeId variable.
