That turns out to be so easy even I figured it out! :-)
Create an Overlay of your own and implement the draw() method, i.e.
private class ProximityOverlay extends Overlay {
public void draw(Canvas canvas, MapView mapview, boolean b) {
// draw some stuff in here, like
// canvas.drawCircle(point.x, point.y, radius, paint);
}
}
then simply add this Overlay to the list of Overlays, probably in your
onCreate():
map.getOverlays().add(new ProximityOverlay());
That's it! Android takes care of everything else.
