OnDataChanged is not called - android-studio

Question

I have a problem with comunication between my phone and wear device. I decided to add wear module to my app. Wear app has just one class (MainActivity)
package cz.johrusk.myapplication;
import android.app.Activity;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.wearable.view.WatchViewStub;
import android.util.Log;
import android.widget.TextView;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.ResultCallback;
import com.google.android.gms.wearable.DataApi;
import com.google.android.gms.wearable.DataEventBuffer;
import com.google.android.gms.wearable.PutDataMapRequest;
import com.google.android.gms.wearable.PutDataRequest;
import com.google.android.gms.wearable.Wearable;
public class MainActivity extends Activity implements GoogleApiClient.OnConnectionFailedListener,DataApi.DataListener {
GoogleApiClient mGoogleApiClient;
private TextView mTextView;
static final String TAG = MainActivity.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final WatchViewStub stub = (WatchViewStub) findViewById(R.id.watch_view_stub);
stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener() {
#Override
public void onLayoutInflated(WatchViewStub stub) {
mTextView = (TextView) stub.findViewById(R.id.text);
}
});
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Wearable.API)
.addConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {
#Override
public void onConnected(Bundle connectionHint) {
Log.d(TAG, "onConnected: " + connectionHint);
sendNumber(1);
Log.d(TAG,"BBBBBBBB");
}
#Override
public void onConnectionSuspended(int cause) {
Log.d(TAG, "onConnectionSuspended: " + cause);
}
})
.addOnConnectionFailedListener(this)
.build();
mGoogleApiClient.connect();
Log.d(TAG,"mGoogleApiClient connected;");
}
#Override
public void onConnectionFailed(#NonNull ConnectionResult connectionResult) {
Log.d(TAG,"FAILE" + connectionResult);
}
public void sendNumber(int number) {
PutDataMapRequest putDataMapRequest = PutDataMapRequest.create("/number");
putDataMapRequest.getDataMap().putInt("number",number);
putDataMapRequest.getDataMap().putLong("Time",System.currentTimeMillis());
PutDataRequest putDataReq = putDataMapRequest.asPutDataRequest();
putDataReq.setUrgent();
Wearable.DataApi.putDataItem(mGoogleApiClient, putDataReq)
.setResultCallback(new ResultCallback<DataApi.DataItemResult>() {
#Override
public void onResult(#NonNull DataApi.DataItemResult dataItemResult) {
if (!dataItemResult.getStatus().isSuccess()) {
Log.d(TAG,"Fail");
}
else{
Log.d(TAG,"Succes");
}
}
});
}
#Override
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
#Override
public void onDataChanged(DataEventBuffer dataEventBuffer) {
Log.d(TAG,"TEST");
}
}
I quess that "Wearable.DataApi.putDataItem" should call WearableListenerService in my phone app. Here is that service:
package cz.johrusk.showsmscode.service;
import android.util.Log;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.wearable.DataEvent;
import com.google.android.gms.wearable.DataEventBuffer;
import com.google.android.gms.wearable.DataMap;
import com.google.android.gms.wearable.DataMapItem;
import com.google.android.gms.wearable.Wearable;
import com.google.android.gms.wearable.WearableListenerService;
public class WatchListener_service extends WearableListenerService {
#Override
public void onCreate() {
super.onCreate();
GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Wearable.API)
.build();
mGoogleApiClient.connect();
}
#Override
public void onDataChanged(DataEventBuffer dataEventBuffer) {
Log.d("prijato","number is: ");
for (DataEvent dataEvent : dataEventBuffer) {
if (dataEvent.getType() == DataEvent.TYPE_CHANGED) {
DataMap dataMap = DataMapItem.fromDataItem(dataEvent.getDataItem()).getDataMap();
String path = dataEvent.getDataItem().getUri().getPath();
if (path.equals("/number")){
int number = dataMap.getInt("numa");
long time = dataMap.getInt("timestamp");
Log.d("received","number is: " + number);
}
}
}
}
}
However, onDataChanged method in WatchListener_service isn't called. onResult method inside ResultCallbacks print "Succes" so it seems that DataItem is send correctly.
I already find many similar problems on Stackoverlflow so I checked all these things:
Both modules has same applicationId
Both modules use 'com.google.android.gms:play-services-wearable:9.0.0'
SetUrgent is used to putDataRequest so there shouldnt be any delay.
WearableListenerService has declared correct intent filter in Manifest :
action android:name="com.google.android.gms.wearable.DATA_CHANGED"
data android:scheme="wear" android:host="*"
Both phone and Wear app run on physical device. My question is... What should I do to fix this issue?
Thanks

Answer 1

Check if both apps have the same debug key. I had some problems with that and problem was different keys for both apps (wear and mobile).
PS: The Android Wear API is ridiculous. I quit developing for Wear because of how terrible is that API that doest not work as they say this should.
