Thanks again Dianne, i don't think your solution will do as i also need to know which class i am in (i need to know that 0x7f020000 is a drawable and that 0x7f030000 is a layout). Is it possible to get the information i need through the AssetManager? any way to hack into the binary data structure? if not i guess it is back to the drawing-board for me.....
