Close app if double back pressed using fragments

Question

Im combining replace with addtobackstack for new fragments added the activity. like so:

mFragmentManager.beginTransaction().replace(R.id.content_frame, searchFragment,"Frag_Search").addToBackStack("searchFragment").commit();

When the user back presses twice, i would like the app to exit

I tried some answers here: Clicking the back button twice to exit an activity but the don't close the app, just keeps removing the last fragment.

Follow the link you posted, but instead of calling super.onBackPressed call finish. — Gabe Sechan, Jul 10 '16 at 20:33

You can exit from your fragment by calling getActivity().finish()

You may have to empty the backstack first by doing something like this

private void popEveryFragment() {
    // Clear all back stack.
    int backStackCount = mFragmentManager.getBackStackEntryCount();
    for (int i = 0; i < backStackCount; i++) {

        // Get the back stack fragment id.
        int backStackId = mFragmentManager.getBackStackEntryAt(i).getId();

        mFragmentManager.popBackStack(backStackId, FragmentManager.POP_BACK_STACK_INCLUSIVE);

    }
}
