I've tried it with no de-bugger, on the emulator, and on actual G1
hardware, I can't seem to get rid of the problem entirely. I only
process and use one bitmap at a time, bitmaps are recycled after use,
and I invoke gc(). The Runtime free memory indicates that I always
have over 10 MB free, each bitmap is less than 3.5 MB, yet this
problem still ocurs intermittently. I've about run out of ideas, I
wish I knew if there were a solution to this problem, or if it is a
bug in BitmapFactory. There isn't another way to produce bitmaps from
files in Android as far as I know, so this is a big probem.
