Yes, Fragments helps a lot. I did multi tasking using activities, Asyctask, hidden layouts in a Relative lout,etc.
But Fragments is the best solution, I believe.Not sure about compatible jars of fragments that works in lower versions, but heard that it works equally good. I think every knows that some UI features still very in iPhone, we can easily overlay a screen on another without coding effort or less coding. But Android certainly gives the rich ness and User friendly experience with fragments that are better than iPhone in some scenarios. regards On Wednesday, May 16, 2012 8:13:12 PM UTC+5:30, Streets Of Boston wrote: > > " from your talking it seems that in your mind the app needs to store > every user's move in database > and restore it in every onCreate(), hey, have you every programmed an > android app?
