Android: application crashes on Picture.createFromStream()_问答_开发者

My app displays a series of pictures. For memory reasons, I want to serialize these pictures when they are not in use. The serialization seems to work (doesn't throw exceptions or crash), but the application crashes on my Picture.createFromStream() call. I can't find anything informative in the LogCat output, nor does the failed call throw a Throwable. Any advice?

That is a crash in native code, and therefore qualifies as a platform bug. Very similar stacktraces appear in bug reports 7468 and 2535.

Am afraid you will have to find a workaround fairly blindly. For starters, how many times do you draw to the Canvas between beginRecording() and endRecording()? How big is a typical serialized file?
