I'm aware this post is dead, but this is probably the easiest way you can solve this issue.
In the manifest in the application tag, you write:
This requests a larger heap, which (in my experience) scales based on what you use. Without it, I have often gotten 8 MB, but with it I have had up to 20 MB (for the app in question, that prevented crashing). (Please note that these numbers are not guiding: The numbers depend on the device and how heavy on RAM your app is).
