Android : Can't get location by WIFI on android TV

Question

here's my problem :

I have this code (from this tuto) :

public Location getLocation(Context act) {
    try {
        locationManager = (LocationManager) mContext
                .getSystemService(LOCATION_SERVICE);

        // getting GPS status
        isGPSEnabled = locationManager
                .isProviderEnabled(LocationManager.GPS_PROVIDER);

        // getting network status
        isNetworkEnabled = locationManager
                .isProviderEnabled(LocationManager.NETWORK_PROVIDER);

        if (!isGPSEnabled && !isNetworkEnabled) {
            // no network provider is enabled
        } else {
            this.canGetLocation = true;
            if (ContextCompat.checkSelfPermission(act, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
                    // First get location from Network Provider
                    if (isNetworkEnabled) {
                        locationManager.requestLocationUpdates(
                                LocationManager.NETWORK_PROVIDER,
                                MIN_TIME_BW_UPDATES,
                                MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
                        Log.d("Network", "Network");
                        if (locationManager != null) {
                            location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                            if (location != null) {
                                latitude = location.getLatitude();
                                longitude = location.getLongitude();
                            }
                        }
                    }
                // if GPS Enabled get lat/long using GPS Services

                if (isGPSEnabled) {
                    if (location == null) {
                        locationManager.requestLocationUpdates(
                                LocationManager.GPS_PROVIDER,
                                MIN_TIME_BW_UPDATES,
                                MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
                        Log.d("GPS Enabled", "GPS Enabled");
                        if (locationManager != null) {
                            location = locationManager
                                    .getLastKnownLocation(LocationManager.GPS_PROVIDER);
                            if (location != null) {
                                latitude = location.getLatitude();
                                longitude = location.getLongitude();
                            }
                        }
                    }
                }
            }
        }

    } catch (Exception e) {
        e.printStackTrace();
    }

    return location;
}

It works just fine on AVD and phone but with android TV, it won't work.

My android TV is on "use Wifi to estimate location" ( and is "on" of course) so I thought that even if there is no GPS_PROVIDER it at least should go on NETWORK_PROVIDER but isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER); is always false.

I specify that I have wifi on my tv and when I entered google map in my browser it found me.

Can someone please help me understand why it doesn't work or propose an other solution to get my location (apart from google play service, my TV doesn't have it installed)...

What is your Android version? If Marshmellow(6.x), did you get Runtime permissions? — dustblue, Jun 09 '17 at 12:22
@dustblue My min SDK is 21 and max 25, my TV is on API 22, and yeah I have run time permission — Kolopox, Jun 09 '17 at 12:45

You can use the LocationServices API in Google Play Services to obtain the user's location. It is a "FusedLocationProvider", incorporating a variety of inputs including Wi-Fi to determine a user's location.

First: Add the COARSE_LOCATION permission:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

Then init your object:

FusedLocationProviderClient mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);

And get the user's last location through a listener

mFusedLocationClient.getLastLocation()
    .addOnSuccessListener(this, new OnSuccessListener<Location>() {
        @Override
        public void onSuccess(Location location) {
            // Got last known location. In some rare situations this can be null.
            if (location != null) {
                // ...
            }
        }
    });

You may refer with this thread wherein it stated that you will only need these permissions in you manifest:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />

Then replace the condition to check if you GPS is enabled:

if (isGPSEnabled) {
   if (location == null) {
       locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MIN_TIME_BW_UPDATES,MIN_DISTANCE_CHANGE_FOR_UPDATES, (LocationListener)this);
       Log.d("GPS Enabled", "GPS Enabled");
       if (locationManager != null) {
           location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
           if (location != null) {
               latitude = location.getLatitude();
               longitude = location.getLongitude();
           }
       }
   }
} //end-if isGPSEnabled

Additional references:

LocationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER) is not reliable, why?
There are 2 conditions must be met that LocationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER) returns true.
- Some internal state is ready for network location.
- Network location is enabled on setting screen.
.isProviderEnabled(LocationManager.NETWORK_PROVIDER) is always true in Android

...So long as the network provider is not disabled in Settings, isProviderEnabled(LocationManager.NETWORK_PROVIDER)will return true. The provider being enabled has nothing to do with whether the provider will work given your lack of network connection.

Hope this helps!

Sorry for the late answer, the code you gave me is the one I already use et I already have the permissions. The thing that bother is the part : **Some internal state is ready for network location**, I don't know if my state is ready or not :/ and I tried to put **isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);** to true but when I do my Location is null... — Kolopox, Jun 16 '17 at 14:35
