I'm developing an Android app which uses multiple large images in several of its activities. Each image is around 1280x800 and I load about 2-4 of these images for each Activity. I realize that these images are very large in terms of the memory that is allocated to each individual app on a device, but how can I display them at their original resolution without running into a java.lang.OutOfMemory error? I need these images to be displayed at their full size on a screen (scaling is done automatically by xml when the screen is smaller than the image). I saw several solutions involving shrinking down images into thumbnails and storing those into memory, but wouldn't that cause the image to lose it's original size/resolution? Thanks for your help!
This article describes pretty well how to create a heap dump and analyze it using Eclipse MAT. This will help you find the most likely suspects for memory leaks pretty quickly.
Again I point you to this great link I found from another SO Question that has tutorials of how to properly over come the problem.
