Great! Found the problem (I didn't know this was a problem). I was starting the same activity I was in from a button press from within the activity (thought that was easier than re-initializing everything). Apparently the new activity was being launched before the previous one got a 'onDestroy' and to my surprise after the new activity (the same class) launched, onDestroy was being called on the new instance!! This was causing a severe leak which I've now fixed and total allocated heap doesn't go above 2MB (phew!)
