java.lang.Out OfMemoryError. Failed to allocate a 8294412 byte allocation with 7320368 free bytes and 6MB until OOM.

I'm only using 1 actual picture in the app. Do generated PImages take a lot of memory or something? My app runs at 1fps when it even works. Are pixel array edits feasible on mobile or is it fundamentally too slow? My app only has 5 PImages and 3 PGraphics elements. 1 of the Pimages is a .png file.
