I'm not receiving any location updates with the following code. Any ideas why? It works on another tablet.

There are two providers, "passive" and "gps" (why not "network" even though WLAN is connected?). Last known location is also null.

Crystal Sky has Android 5.1.1 so requesting permission at runtime is not required. I have declared INTERNET, ACCESS_NETWORK_STATE, ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION permissions in the manifest file.


public class MainActivity extends AppCompatActivity implements LocationListener {

    private static final String TAG = MainActivity.class.getName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        LocationManager locationManager = (LocationManager)getSystemService(LOCATION_SERVICE);
        Log.d(TAG, "Providers: " + locationManager.getProviders(true));
        Location loc = locationManager.getLastKnownLocation(LocationManager.PASSIVE_PROVIDER);
        Log.d(TAG, loc == null ? "no location" : loc.toString());
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
        locationManager.requestLocationUpdates(LocationManager.PASSIVE_PROVIDER, 0, 0, this);
    }

    public void onLocationChanged(Location location) {
        Log.d(TAG, "location changed");
    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
    }

    @Override
    public void onProviderEnabled(String provider) {
    }

    @Override
    public void onProviderDisabled(String provider) {
    }

}

Never mind, Crystal Sky's GPS didn't work indoors.
