Android DataItem Not syncing with emulator wearable

Question

I have been googling for 5 straight days and still can't find the solution to my problem so I desperately publish my question in the hope that somebody can help me.

I've been trying to send a DataItem to an emulator wearable through the WearableAPI. I will describe all the steps i'm following and specify the code I wrote.

Thanks in advance!

1. I start the emulator.
2. I open Android Wear app on my own device and pair up the emulator.
3. I forward the ADB through adb -d forward tcp:5601 tcp:5601 in the platform-tools folder.
4. I start the mobile app on my phone through Android Studio
5. I start the wear app on the emulator through Android Studio
6. I wait for something to happen but nothing happens.

Mobile Code:

@Override
protected void onCreate(Bundle savedInstanceState) {
    ...
    initComponents();
}


private void initComponents() {
    ...
    initWearLink();
}
@Override
protected void onStart() {
    super.onStart();
    mGoogleApiClient.connect();
}

@Override
protected void onStop() {
    super.onStop();
    if (mGoogleApiClient.isConnected()) {
        mGoogleApiClient.disconnect();
    }
}


// ---------------------------- WEARABLE PART ----------------------------

private void initWearLink() {
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            // Request access only to the Wearable API
            .addApi(Wearable.API)
            .build();
    increaseCounter();
}


private static final String COUNT_KEY = "efficiencyaide.dev.pv.studea.count";

private GoogleApiClient mGoogleApiClient;
private int count = 0;


// Create a data map and put data in it
private void increaseCounter() {
    PutDataMapRequest putDataMapReq = PutDataMapRequest.create("/count");
    putDataMapReq.getDataMap().putInt(COUNT_KEY, count++);
    PutDataRequest putDataReq = putDataMapReq.asPutDataRequest();
    PendingResult<DataApi.DataItemResult> pendingResult =
            Wearable.DataApi.putDataItem(mGoogleApiClient, putDataReq.setUrgent());
}


@Override
public void onConnected(@Nullable Bundle bundle) {

}

@Override
public void onConnectionSuspended(int i) {

}

@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

}

@Override
    public void onDataChanged(DataEventBuffer dataEventBuffer) {

}

            if (item.getUri().getPath().compareTo("/count") == 0) {

(Sorry for the long post/code but i didn't want to miss anything out)

What I already know/debugged:

1. The onDataChanged() function is never called
2. The onConnected() function in the wearable device is never called
3. If I start the app on the wearable, it says: "new version of Google Play services is needed. It will update itself shortly". After this message, the app starts.
4. [EDIT]: Setting ADB debuggin enabled does not help.

I hope that somebody can help me with this information. I apologize for the amount of code.

Thanks in advance

Answer 1

I have had the exact same issue yesterday and couldn't find out why.

Today I started everything up again and found this link that showed me how to connect the wearable emulator to the phone. I did everything before I found this link, except for 1 thing: enable ADB debugging on the wearable.

In the end, this was causing my problems of connectivity.

To the point: Enable ADB debugging on the emulator to make it work.

To do this, go to options --> find "about" --> click a few times on "Build number" --> go back to options --> developer options --> enable ADB debugging.

Hope this helps!
