How to get the Latitude and Longitude on Map in Android?

You'll have to manage the LongClick event, and then use the code to find out longitude and latitude with the following code:

GeoPoint geoPoint=mapView.getProjection().fromPixels((int)event.getX(),(int)event.getY());
int latitude = geoPoint.getLatitudeE6();
int longitude = geoPoint.getLongitudeE6();

where 'event' is the object of 'MotionEvent'.

Use any other event according to your case.
