Question

Having a OOM error with Bitmap factory for my android devices.

Out of memory on a 12582928-byte allocation.

which is weird to me. It is very large. THe files themselves, are images tank on the tablet and downloaded. So the images might reach a 1.2meg jpg or so at the upper bounds.

After it says that Error, it spits out the AndroidRuntime error log for a fatal exception:

I Do have a lot of images processing with this function simultaneously. I didnt think the BitMapFactory was being overworked at all from the different threads running.

that’s not true. A 32bit bitmap will require width * height * 4 bytes in order to be allocated. Remember to recycle your bitmap when you do not need it. Also downsample it, if you can
