In the version 0.3.0 issues #5 (refactoring of the main layout file) and #6 (move to sd-card) issues are solved.

Cleaned OverlayMediator. Moved strings to /res/values/strings.xml Solved the bug with disappearing OverlayItems. The actual reason was the caching of OverlayMediator object. The instance variable “activity” was the old one, and the getOverlays from the activity’s lusitesMap were old. So it couldn’t work. The solution is to force OverlayMediator to renew its instance variable LUSitesActivity activity each time the static method getInstance is called: public static OverlayMediator getInstance(Context context) { if (singleton == null) { singleton = new OverlayMediator(); } singleton.

OverlayController is actually more Mediator. It keeps track of current OverlayItem and triggers toggling of marker highlighting. In order to provide clear code the name has been changed to OverlayMediator. The singleton variable now is called singleton. And static method getOverlayController is now getInstance().
