You need to call:
mapOverlays.add( itemizedOverlay );
also, if you're adding/removing overlay items to/from ItemizedOverlay,
you may need to call setLastFocusedIndex(-1) (or whatever the method
is). I think in your case you won't need to worry with this as you
only call "addOverlay" and "populate" once.
