[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:

It would be nice to get some information about what are you think about.
Thank you for your attention and support.
