this one helps. The only thing that I can think of is to pass the zoom level into the overlay when it changes in the map and then make the decision on what to draw in the overlay.

I think the issue was by ths following , It's not easy. The only way I know is to create your view (e.g. layout with background and text view) and then render it as a bitmap.
code :
public static Bitmap loadBitmapFromView(View v) {
    DisplayMetrics dm = v.getContext().getResources().getDisplayMetrics();  
    Bitmap b = Bitmap.createBitmap(Math.round(v.getMeasuredWidth() * dm.density), Math.round(v.getMeasuredHeight() * dm.density), Bitmap.Config.ARGB_8888);                
        Canvas c = new Canvas(b);
        v.draw(c);
        return b;
    }
Drawable d = new BitmapDrawable(Utils.loadBitmapFromView(yourView));
        d.setBounds(-35, -30, Math.round(d.getIntrinsicWidth() * dm.density) - 35, Math.round(d.getIntrinsicHeight() * dm.density) - 30);
        overlayItem.setMarker(d);
        overlayListView.add(overlay);

this one helps. BitmapDescriptorFactory can create BitmapDescriptors for you from various objects, e.g.
code :
BitmapDescriptor image = BitmapDescriptorFactory.fromResource(R.drawable.myimage);

it fixes the issue The addTileOverlay method returns a TileOverlay object that you can work with:
code :
TileOverlay overlay = mMap.addTileOverlay(tileProvider.overlayOptions);
overlay.setVisible(false); // Make the overlay invisible
overlay.remove(); // Remove the tile overlay from the map.
List<TileOverlay> tileOverlays = new ArrayList<TileOverlay>
tileOverlays.add(mMap.addTileOverlay(tileProvider.overlayOptions));

// ...

for (TileOverlay tileOverlay : tileOverlays) {
    tileOverlay.setVisible(false);
}

Hope this helps I recently got working with Google Maps API v2 on Android and stumbled upon another obstacle. I cannot figure out how to add an overlay such as in API v1 to display a marker on certain locations using lat and long. I also want it to start in the same town using long and lat. I so far added some code in for the starting position of map BUT it didn't work. I guess I should write it all in java instead of the XML layout but I don't know how to address SupportMapFragment to do anything. , You can add a marker in the onCreate of your FragmentActivity.
