I got this error, too. However, calling mapView.invalidate() on the
enclosing map seemed to take care of this. I suspect that the map
caches the order of the overlays, and this comes out of sync when an
item is removed. Here is the following code I used:
public void clear()
{
ArrayList<oItem> items= this.items;
if (items.size() > 0)
{
items.clear();
this.setLastFocusedIndex(-1);
this.populate();
this.mapView.invalidate();
}
}
This worked for 1.5, Google APIs 3.
