In my android application i am implementing map functionality. it has a tab bar when i jump one activity to another activity through tab its working perfectly. but when i come on map activity and try to move from it through "Back key of device" the entire application freezes and after a couple of seconds I get the dreaded force close dialog appearing and i got error.

This type of problem occur when code get window leak type of problem or when we try to perform many operation on same activity...
