public void getUserLocation() {

    Location location;
    TextView lon = (TextView) findViewById(R.id.textView2);
    TextView lat = (TextView) findViewById(R.id.textView3);
    boolean GpsEnable = false, NetworkEnabled = false;
    locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);




    // String locationProvider = LocationManager.GPS_PROVIDER;

    GpsEnable = locationManager
            .isProviderEnabled(LocationManager.GPS_PROVIDER);
    NetworkEnabled = locationManager
            .isProviderEnabled(LocationManager.NETWORK_PROVIDER);

    // locationManager.requestLocationUpdates(locationProvider,0,0,locationListner);

    if (!GpsEnable && !NetworkEnabled) {
        Toast.makeText(getBaseContext(), "No Provider Availabe",
                Toast.LENGTH_SHORT);

        if (locationManager != null) {
            location = locationManager
                    .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

            lon.setText("Latitude" + location.getLatitude());
            lat.setText("Longitude " + location.getLongitude());
        }
