I suspect that once in a while your bitmap gets into the recycled state just before the Canvas gets a chance to draw onto it here drawable.draw(canvas);.

A quick solution should be not to call bitmap.recycle();, which is not strictly required for android >2.3.3. If you still want to reclaim this memory forcefully, you'll have to find a way to check when the bitmap is indeed no longer needed (i.e., Canvas had a chance to finish its drawing operations).
