[android-developers] Re: Activity lifecycle: invoking finish
If you've noticed, cleaning stuff up let's say clearing a bitmap or nulling an image before you call another activity will result in a temporary blanking out. So onDestroy has to happen after the next activity is fully drawn. If you use 14mb in Activity A and 14mb in Activity B on a 16mb heap device you will run out of memory. I use android:process in the manifest to get around this. On May 11, 11:12 pm, Vikram vikram.bodiche...@gmail.com wrote: This seems to be the order.

[android-developers] Re: Activity lifecycle: invoking finish
If I remember correctly you can use onPause() on activity B that will block before any callback occurs on activity A. Beware though, not to do any long running operation in onPause() as it would stall the app. -- You received this message because you are subscribed to the Google Groups Android Developers group.
