[android-developers] Re: Activity Back Stack and OutOfMemoryError
Android has this particular annoying and weird behavior: Once the heap
inflates to a certain size, no matter how much of it is actually used, you
can no longer allocate files that are larger than the remaining memory.
my guess, you're there.
you should make sure your previous activities use as little memory as
possible and make it a habit of unloading memory which might not
be necessary once activities are changed. This is especially true in apps
that store large bitmaps and even more noticeable if you also have lots of
small objects (memory fragmentation + large bitmaps = OOM exceptions)

Hello,
in the application we open a chooser for selecting photos. I got
frequently crashes mostly from sony by doing this which says:
OutOfMemoryError which raises by showing the bitmaps. The stacktrace which
the
system creates doesn't mention a class of our code which confuses me a bit.
My assumption is that our app can open lots of activities and by opening
the image choose there is not much space left and the crash happen. So far
i read i shouldn't care about do finish(); and activity they
can remain in the activity backstack. It would be great to get a bit more
clued.
Here is the stacktrace i got:

This is especially true in apps that store large bitmaps and even more noticeable if you also have lots of small objects (memory fragmentation + large bitmaps = OOM exceptions) I have inspected the code as Kostya mentioned, and i haven't seen anything what looks like a leak, all the memory was released after causing a gc manually. And i carefully checked every activity and its fragments. I only come to the conclusion that what you said must be the case i have no other answer for that. So will change the behavior of opening lots of activities. But in future it should be wise considered in the concept. Thank you for all readers and who respond.
