Ok, yes this is what I'm seeing. Looks like:
MyActivity: startIntent(maps);
.. logcat says low memory ..
System maps intent starts up, looks good, user plays with it a bit.
User now hits back button
MyActivity: onCreate() gets called, instead of onResume().
on other phones, this works ok, onResume() is called instead of
onCreate() when hitting the back button. I can't see an explicit
message in logcat saying that my activity is being killed after the
low memory message though. I do see this however:
I/ActivityManager( 76): Start proc com.test.myapp for activity
com.test.myapp/.ui.MyActivity: pid=8427 uid=10036 gids={3002, 1005}
For me, it would be good if the app stays in the history stack even
though it was killed - because when the user hits the back button,
wouldn't they be confused if they get taken back to the desktop
instead of my app (which launched them there)?
Thanks
