getting null on current location on Samsung Galaxy Grand android?

I'm try to run my app on Samsung Galaxy Grand but its not showing my current location.

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    // Creating a criteria object to retrieve provider
    Criteria criteria = new Criteria();

    // Getting the name of the best provider
    String provider = locationManager.getBestProvider(criteria, true);

    System.out.println("provider => " + provider);

    // Getting Current Location
    Location location = locationManager.getLastKnownLocation(provider);
    System.out.println("location  " + location);

but always this line return null locationManager.getLastKnownLocation(provider); but this app works fine in other phones like sony and lg.

i have try so many link but still same problem.

getLastKnownLocation() always returning null, all providers are DummyLocationProvider

Android LocationManager.getLastKnownLocation() returns null

Network provider and GPS provider returning null values

<permission
    android:name="xx.xxx.xxx.permission.MAPS_RECEIVE"

Check this for the answer, for short

To programmatically kick start your app for "current location" run the following code before you call getLastKnownLocation

YOUR_APPLICATION_CONTEXT.getLocationManager().requestLocationUpdates(
LocationManager.NETWORK_PROVIDER, 0, 0, new LocationListener() {
    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
    }
    @Override
    public void onProviderEnabled(String provider) {
    }
    @Override
    public void onProviderDisabled(String provider) {
    }
    @Override
    public void onLocationChanged(final Location location) {
    }
});

Some recommendations for fixing GPSTracker issues may be, to set it as 1 min 1 meter

private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 1;
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 ;
