How to exit when back button is pressed?

Question

When a user presses the back button on an intent, the application should quit. How can I ensure the application quits when the back button is pressed?

Answer 1

In my Home Activity I override the "onBackPressed" to:

@Override public void onBackPressed() {    Intent intent = new Intent(Intent.ACTION_MAIN);    intent.addCategory(Intent.CATEGORY_HOME);    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);    startActivity(intent);  } 

so if the user is in the home activity and press back, he goes to the home screen.

I took the code from Going to home screen Programmatically
