Depending on the details, bitmap pixels may be allocated in the VM
heap or in the native heap, but in the latter case, we still debit the
VM's heap by the amount that was allocated, so that in either case we
don't exceed the per-app budget. This may explain why you're running
out of heap even though DDMS doesn't see the allocations.

I've run into this exact same problem a number of times myself. Not
sure if its a bug or just a limitation of the jvm, can't seem to
process more than a few large bitmaps without this occuring, this
always seems to occur when decoding bitmaps from file. Hopefully its
on the radar as a bug and will get fixed at some point. This is a
problem since de-coding bitmaps from file is a fairly common
operation.
