use dispatchTouchEvent() method. it works. why because the MapActivity inherits the dispatchTouch Event not OnTouchEvent from Activity Class. check this documentation

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    int actionType = ev.getAction();
    switch (actionType) {
    case MotionEvent.ACTION_UP:
            Projection proj = mapView.getProjection();
            GeoPoint loc = proj.fromPixels((int)ev.getX(), (int)ev.getY()); 
            String longitude = Double.toString(((double)loc.getLongitudeE6())/1000000);
            String latitude = Double.toString(((double)loc.getLatitudeE6())/1000000);

             Toast toast = Toast.makeText(getApplicationContext(), "Longitude: "+ longitude +" Latitude: "+ latitude , Toast.LENGTH_LONG);
            toast.show();

    }

    return super.dispatchTouchEvent(ev);
}
