The code: http://pastebin.com/5bhKULGd
the problem: When you click an item in the gridview, OCLGenre (OnItemClickListener for Genre view) fires an nullPointer at line 123. I'm trying to understand where the nullPointer comes from but can't find it.
The stack:
ERROR/AndroidRuntime(10511): FATAL EXCEPTION: main
java.lang.NullPointerException

Anyone got a pointer to where to find the source of this nullPointer?
Oke i found my problem By moving the ImageAdapter out of the "browse" class, the "browse" class did not have any reference to the ArrayList 'items'. I could find the problem because, after all, i defined the ArrayList at line 112. However, showGenres() uses a local ArrayList, and the ImageAdapter would put it in "browser.items". Fixed it by removing the local decleration of items on line 145, 154 and 162
