Android - finishing activity from another activity

Question

is there any way, how to finish certain activity from a stack? I have service, which looks for updates, and when update is found, it opens update activity, where prompt for installation will appears. But after the installation appears I want to finish update activity, because it is not necessary to still be on a stack.

Thanks

Answer 1

If the update activity is launching another installation activity, then you may want to override void onActivityResult(int requestCode, int resultCode, Intent intent) in the update activity, providing the following implementation. Also, when the update activity launches the installation activity, it should do so with startActivityForResult(Intent, int), not with startActivity(Intent).

  @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent intent)
  {
    super.onActivityResult(requestCode, resultCode, intent);
    finish();
  }
