public void onLocationChanged(Location location) {
lat = location.getLatitude();
lng = location.getLongitude();
Toast.makeText(
getBaseContext(),
"Location change to : Latitude = " + lat + " Longitude = "
+ lng, Toast.LENGTH_SHORT).show();
GeoPoint p = new GeoPoint((int) (lat * 1E6), (int) (lng * 1E6));
mc.animateTo(p);
