Ran into sort of the same problem myself whilst developing an image gallery - my problem was that loading thumbnails of 5 or so of the images caused an out of memory error. Luckily I was able to implement inJustDecodeBounds and inSampleSize to reduce the quality of my thumbnails and that solved it in my case.
In your case, you're just going to have to put a maximum limit on the memory of an image that your app will take. If the input source is larger than this then use inSampleSize to scale it. However it does you will mean unable to save the image at the same size as the source image, but from my experience this is common among mobile photo editing apps (going back a bit, the LG Viewty for instance could take 5MP photos, but I think the photo editing app could only save them at around the resolution of 1MP). The other option might be to see if it is possible to load only portions of the bitmap (or you could cut it up before opening it in your program) and the piece these back together in a similar fashion to the Google Map tiles.
