How do I finish a task on Android?

I start an activity in a new task and I want to kill the task is when the user leaves it because I think the task is useless when the user leaves.

How can I achieve this on Android? Setting the fi开发者_StackOverflow中文版nishOnTaskLaunch attribute of the root activity has no effect.

You can use the noHistory tag in the manifest , what you can also do is call finish() in onPause for that activity.

make sure your onPause() looks like:

public void onPause(){
  super.onPause();
  finish();
}
