I can maybe help here. I'm an amateur, but the 'out of memory' error is a familiar adversary.
The VM only allows you to use 640k at any given time. I have a program that utilizes hundreds of large bitmap files. Here is how I decided to handle it. (It's clunky and inefficient, but it works.) -I keep solid track of how much memory is being used at any given time. Once the program gets anywhere near 500k, (Just to be safe), I find a way to call finish, recycle bitmaps, and call an intent to start a fresh activity. If it's possible to start a fresh activity when the memory limit gets close, you may want to consider that as an option. -Also, if you are using images. Load your pics into photoshop or the Gimp and make sure they physically as small as you can get them. I don't know if any of that will help, but I've learned the hard way that the 600k ceiling for memory is something you have to keep a count on.
