well it is not this the case.
what i wanted to do is to press a button and then to move the app in background, and the user will be able to see the rest of the app and run a new app if he wishes, the app will run and you are going to be able to see it in background.
i am doing this at the moment by pressing the midle button (home) of me mobile phone.
but i wanted to do it imediatly fro m the app.
