Hi Bob, Wha do you mean bay "abanddoned" - the only callback for activity you can rely on is onPause() , which will be called when it leaves user focus. After this it may be killed sometime, or brought to front( onResume() will be called ) I would delete old photos when new one is arrived. As for data keeping, you may store queue on provate preferences. regards, -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
