Alright thanks all, got this working. On 2.0+ devices, I use the ExifInterface class to see if the image needs to be rotated. If so, I can load the image at a downsampled size and do the rotation myself. Like Streets Of Boston pointed out, I don't know of a good way to do the rotation of the full high-res image.
