Exit android app on back pressed

Question

I am building an Android App. How to exit an Android App when back is pressed. Android version is 2.3.3 and above. The Android App goes to previous activity which i don\'t want.

Answer 1

I know its too late, but no one mentioned the code which i used, so It will help others.

this moveTaskToBack work as same as Home Button. It leaves the Back stack as it is.

 public void onBackPressed() {
 //  super.onBackPressed();
    moveTaskToBack();
  }
