In my app, i've been dillegently 'unloading' bitmaps when i need memory. I clear out as much as I can.
E.g. when a view becomes invisible (onPause) or just before you start loading a big bitmap: - do a setImageBitmap(null) (or similar methods, depending on which class of View you're actually using) on these views - clear any bitmap cache I actually implemented a global 'bitmap memory notifier' to any instance that may be interested in it. Instances can register with this notifier as a listener. If some part of my code needs to create a large bitmap, it calls this notifier which causes all listeners to get notified and they can take action to clear out as much bitmap-memory as possible (someBitmap.recycle(); someBitmap = null; clean caches; etc.) So far, this scheme has served me well. Before i got a lot of OOM- errors. Now i get a looooot less. And, if i still get one, i try to handle it gracefully.
