"Memory used by an app" is complicated. You shouldn't be using ActivityManager.getProcessMemoryInfo() for regular program logic. However, if you want to start to understand what these numbers mean, you can read a post I made about it here: http://stackoverflow.com/questions/2298208/how-to-discover-memory-usage-of-my-application-in-android/2299813#2299813 -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.
