requestLocationUpdates never called in android service

Question

I'm developing android application that reads the latitude and longitude of the user periodically in the background , then checks if the lat and lng is within a predefined boundary or not. If No we shall close the application.

I'm using android service and locationManager for this requirements.However, the below code is worked perfectly fine when I tried to use it in a new android project. but when I add it to my original project the method requestLocationUpdates() is never called .. I have spent 2 days trying to figure out what the main cause of this problem. I have tried all the solution in stack overflow but nothing worked for me.

I have added these permission (ACCESS_FINE_LOCATION , ACCESS_COARSE_LOCATION)
I have added these dependenies

implementation 'com.google.android.gms:play-services-maps:11.8.0' compile 'com.google.maps.android:android-maps-utils:0.5'
I have tried both providers (GPS and Network)
I'm Calling this service in my main activity
I've add the service in my manifest

This is My code

public class LocationControService extends Service {

List pointsList = new ArrayList<>();
private LocationManager locationManager;
double lat;
double lng;
LatLng userLocation;
private static Timer timer = new Timer();


// run on another Thread to avoid crash
private Handler mHandler = new Handler();


@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public void onCreate() {


    // It Should Be A Query From The DB
    pointsList.add(new LatLng(24.75057, 46.57516));
    pointsList.add(new LatLng(24.81291, 46.74545));
    pointsList.add(new LatLng(24.65076, 46.85119));
    pointsList.add(new LatLng(24.57335, 46.67404));

    locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

    startService();
}

private void startService()
{
    timer.scheduleAtFixedRate(new TimeDisplayTimerTask(), 0, 10000); }

@Override
public void onDestroy() {
    timer.cancel();}



class TimeDisplayTimerTask extends TimerTask {

    @Override
    public void run() {
        // run on another thread
        mHandler.post(new Runnable() {

            @Override
            public void run() {
                getUserLocation();

            }

        });
    }

}



private void getUserLocation () {


    try {

        Location location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

        locationManager.requestLocationUpdates( LocationManager.NETWORK_PROVIDER,0 , 0, new LocationListener() {
                    @Override
                    public void onLocationChanged(Location location) {

                        lat = location.getLatitude();
                        lng = location.getLongitude();

                        userLocation = new LatLng( lat,lng);


                        if (isUserWhithinBoundray(userLocation))
                            Toast.makeText(getApplicationContext(),"You Are Within The Boundray", Toast.LENGTH_LONG).show();

                        else {
                            Toast.makeText(getApplicationContext(), "You Are Out Of The Boundray", Toast.LENGTH_LONG).show();
                            // SHOW DIALOG MSG .. OPEN SIGNIN INTENT

                            Intent myIntent = new Intent(LocationControService.this, MyDialog.class);
                            LocationControService.this.startActivity(myIntent);



                        }


                        locationManager.removeUpdates(this);
                    }

                    @Override
                    public void onStatusChanged(String s, int i, Bundle bundle) {

                    }

                    @Override
                    public void onProviderEnabled(String s) {

                    }

                    @Override
                    public void onProviderDisabled(String s) {
                        Toast.makeText(getApplicationContext(),"Turn the GPS on", Toast.LENGTH_LONG).show();
                        Intent viewIntent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                        startActivity(viewIntent);

                    }
                }
        );

    }

    catch (SecurityException e) { }

}




public Boolean isUserWhithinBoundray (LatLng userLocation) {
    return PolyUtil.containsLocation(userLocation,pointsList,false);
}

}

I have added the LOGs @CaoMinhVu Mentioned :

1. print a log inside getUserLocation, before try

 Log.d("Trck","Before Try");

2. print a log inside catch: e.printStackTrace() and print a log here also

  e.printStackTrace();
  Log.d("Trck", e.getMessage() );

3. Print a log inside each callback ( I've done the same for each callbacl )

 Log.d("Trck", "onLocationChanged" );

Here is the result :
