                MY_PERMISSIONS_REQUEST_FINE_LOCATION);

                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // permission was granted, yay! Do the
                // contacts-related task you need to do.
             getLocation();
            } else {
                // permission denied, boo! Disable the
            }
            return;
        }
    }
