Perhaps this (garbage collection on background applications) actually does happen but just isn't documented, then freeing memory before going into the background is a useful thing.
Yes thats why i want to freeing memory just before going into the background but I am not getting callback which will get called after pressing home key. However after reading your reply, now i also have doubt even if i clear memory ( initialized it with null), it will call garbage collector or not but it is more better than not releasing memory at all. if in case garbage collector get run after assigning null, my purpose will be achieved.
