Android app stops without error on orientation change

Question

I'm developing an app that makes use of the Google maps API. I've developed two separate layouts to handle both types of orientation (portrait and landscape). Everything works fine except I'm having a very strange bug.

Sometimes, when I flip the phone from portrait to landscape or vice versa, the app will simply close. There's no error visible on the screen. There's no exception thrown in Logcat. It's almost as if my app simply calls finish() and quits (which isn't anywhere in the program). I also am not trying to save any state on rotation yet, so as of right now the app effectively restarts. Sometimes, I'll flip it 50 times before this happens, and sometimes twice.

The only thing I can find on this problem is this: Android Screen Orientation Change Causes App To Quit

It doesn't really help at all.

There is, however, one large message that pops up in the normal log.

From the looks of it, my app is trying to access memory address 00000000 and is throwing a segmant fault.

I'm running Android 2.2 on a HTC Evo 4G. I haven't been able to test the app on other hardware yet, but I'd like to find out why it's crashing at all.

EDIT:

I ran the test on the emulator. Now, I get an OutOfMemory exception for loading bitmaps. I only load two bitmaps programmatically. Everything else is through xml.

Line 92 of my activity is setContentView(R.layout.main), so it seems to crash when it inflates the main layout. It's having problems loading the bitmaps I use for backgrounds. How do I dump the memory of the bitmaps or reuse them? I'm not controlling those from the program, so it's all automated on Android's part.

Odd. When I run it on the simulator, I get an `OutOfMemoryError: bitmap size exceeds VM budget` error. I get two bitmaps from calling `getResources().getDrawable()`. Even when I call `recycle()` and set their reference to null for GC, it still happens. It seems that it's allocating the bitmaps that I use in the xml layouts and won't free them on orientation. I'll edit with the emulator error. — DeeV, Aug 24 '11 at 18:11

It seems that error is produced by libskia.so. See this thread for similar error. Error seems to be produced when memory is low.

How do you load your resources, e.g. images? On orientation change, Activity gets recreated and all resources are usually loaded again. Try caching your images, but beware of memory leaks (i.e. cache bitmaps, not drawables).

Update

So this seems to be triggered by image loading. Google Maps also downloads and instantiates a lot of images (map tiles) so this might make it worse.

If your image is very big, then try to scale it when loading.

Also use onRetainNonConfigurationInstance / getLastNonConfigurationInstance to cache bitmaps for faster loading and less memory usage.

Update:

Also, use images in XML files of the appropriate sizes as they appear on screen as bigger images inflate the problem.

I only manually load two bitmaps for use of the entire app. I dump them for garbage collection at onPause() and it stil happens. More description in my edit. – DeeV Aug 24 '11 at 18:20
Thanks for the reply. I did try those tricks, but the issue still remains. The issue seems to be it never actually cleans up the bitmaps from the previous inflated layouts. – DeeV Aug 24 '11 at 19:30
