How can i quit an app (android)

Hi all, is there a way to quit an app (a button or function to do it) or is it impossible on BB?
I need to exit from the app and unload it from memory

 

Sorry i forgot to say i tried 'Exit' function on a button and it doesn't work on my android device
The software is great but...It seems so unuseful without this function...

 

Hello, Button EXIT not work in Android, Exit with button "Back", only work in BB 1.3.6, in BB 2 not work
Please, if you question, enter your version of BB, Operating System, etc ... thank you.
You can also use the search in this forum, it is free:

Hi, thanks.... so there's no way to unload an app? Only force close is a way to exit a game?

 

Hello, games created with BB 2, force close.

 

I need that functionality too. Actually this is the basic thing I wonder why they don't have it
