  this.setCon         


        

Answer 1

A bad way to kill the application would be System.exit(0)

Edit: I believe I owe some explanation. Android handles the application lifecycle on its own, and you are not supposed to 'ForceClose' it, and I don't know any good way to do it. Generally its ok if your application is still alive in the background, this way if user launches it again it will pop up quickly.
