How Do You Implement "follow Me" Using The Mylocationoverlay Class?

I made an application which shows the current location of the user using the MyLocationOverlay class. However, when the user changes his location, the marker is not recentered. How

Solution 1:

What I do is extend MyLocationOverlay as an inner class of my MapActivity. Then, I override onLocationChanged and use animateTo on my MapController in that method.

@Override
public synchronized void onLocationChanged(Location location) {
    if (location != null) {
        mapController.animateTo(
                new GeoPoint((int) (location.getLatitude()*1e6),
                             (int) (location.getLongitude()*1e6));
    }
    super.onLocationChanged(location);
}
