Romain- Thanks so much for your response! That helps me understand the memory usage amount... What I don't get is why would Android not be able to free up 4MB of RAM for me? Isn't memory Android's job? My drawable is only referenced once, in my XML, and that XML is only being loaded in one Activity's onCreate. That Activity may run multiple times in one run of the app, but it always finishes and should therefore be destroyed by the system, removing all pointers to the View and the Drawable in it, and on the next GC run it should be freed.. At least that's the theory.... Am I missing something?
Android is surely capable of handling a 4MB drawable in RAM, is it not? Maybe there is a way I can compress this image? I hope to maintain full-resolution on the hi-dpi devices and it needs to fill the screen in both landscape and portrait. I could shrink it down to 854x854 as the minimum dimension to make it fit perfectly on the Droid's pixel-packed screen... Thanks guys!
