You may implement android.location.LocationListener interface This will keep track of the User's Current Location.

On a click of mouse you may invoke last location from this Listener.

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1l,100,locationListener);
