Please one more thing. When there is a change in the location the map does change but the Icon is gone. how do i validate the Icon into the new change? – rayman Jul 1 '11 at 7:12

this is where your location changes

public void onLocationChanged(Location location) {
    int lat = (int) (location.getLatitude() * 1E6);
    int lng = (int) (location.getLongitude() * 1E6);
    GeoPoint gpt = new GeoPoint(lat, lng);
    mapController.setCenter(gpt);
    mMapView.invalidate();
}

But as you can see it does not add new icon to the overlay.

You should clear the previous items

items.clear()

(if you want the "old" icon to be removed when the new one is created) and then add the new point (gpt) to the items.

items.add(new OverlayItem("Title", "Description", gpt));

and so on...
