Hello,
I have an app that works ok from 2.2 to 4.0 since 4.1 I started to have
"java.lang.IllegalArgumentException:
Cannot draw recycled bitmaps".
After some optimizations and tests, i finally find that for an unknown
reason android wants to refresh my listview after the onstop during screen
off event on some devices.
The activity is a not so complex listview with lazy loading of images.
To optimize memory in the onstop of my listview activity i recycle bitmaps
with a simple : (needed since there lot's of activity like this one and on
some devices bitmaps are not garbaged quickly enough).
> final AbsListView listView = (AbsListView)
> findViewById(R.id.mediaslist_list);
> int c = listView.getChildCount();
> for (int i = 0; i < c; i++) {
> adapter.recycleView(listView.getChildAt(i));
> }
>
in the OnStop(); where the recycleView just recycle the bitmap.
In Nexus 7 or emulator in landscape, when i shutdown screen the onstop is
called but since it wants to go to portrait for lock-screen it does
something with the listview and try to redraw it.
Leading to the error :
java.lang.IllegalArgumentException: Cannot draw recycled bitmaps

Is there something I missed in activity lifecycle or listview one ? (like
bitmap references saved with instancestate since JB ?)
The app works perfect when orientation changes, just this specific case
gives this specific result . And on screen unlock the activity is restarted
so the crash is half handled by the OS.
The problem is that I use ACRA lib so users gets notifications about this
crash even if it's not really blocking due to activity restart.
Regards,
Tolriq.
