"if you had a png that was mostly white so compressed very well you might have a 200KB png file that actually is using 6MB of RAM on your device" - I didn't know it can use so much space :/
About 90% of images (in total application, about 60% of them (this one 1KB) are used per activity, so I would say approx. 50KB per activity) are 1KB (or less), 5% are 10-60KB and 5% are 1-5KB so I think image size isn't a problem. So I'm pretty sure it's A) but how to solve it? And yes, I'm constantly switching between two-three activities (and I disabled rotation for some other reasons).
