Which function closes an application in Android?

Question

Java

I am writing a program for Android. There are 2 Activities in the program. In the first activity there is a button, when clicked, the user gets to the second activity. It is necessary to make it so that, being in the second activity and when you click on the back button, the application closes, and does not return to the first activity, as by default.

@Override
public void onBackPressed() {
  // TODO Auto-generated method stub
  // super.onBackPressed();
  // Что тут написать для закрытия приложения?
}

Answer 1

finish();

Answer 2

There is no such feature. Moreover, the user does not need it, because. it has a home button. It's strange that you need it.
You can call finish on all living Activity instances.
