Android has a whole mechanism for this: http://blog.rlove.org/2010/04/why-ipad-and-iphone-dont-support.html That explains the problem, but doesn't explain the Android answer to it, which is here: http://developer.android.com/guide/topics/fundamentals.html The section "Component Lifecycles" gives the summary. They call each app's onPause() method when it is obscured from visibility on the screen, and that method is responsible for recording everything the app needs to restart itself and get back to the same screen display (what file it was working on, how far down the file it was, etc). Then, any process whose onPause() method has been called is considered a cache, and can be killed without warning by the kernel. (I'm not advocating using this system -- I've only barely been exposed to it. But it's useful to see how others have solved the problem you're facing, before making your own solutions.)
