title: Go to home screen from Android Activity
body: <p>I'm making an application in android and I want to implement a button such that whenever it is pressed, I just reach back to my home screen. I know that we have the hardware key and soft keys( when there are no hardware keys) which implements this, but I want to add this functionality for this application. Does anybody has any idea how to do it?</p>
  
  <p>Thank you</p>
