About the activities being 3.0: Yes, but it's possible on 1.6 and up as well - to some extent - using the Android Compatibility Library.
I think that the View Toggle type design should be possible without serious implications to the memory footprint. Fragments are designed to work well with the back-stack. I can imagine that memory is clean up where necessary (as long as your activity - or some other more global class - doesn't hold references to each possible Fragment). -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
