 Handler handler = new Handler();
    Runnable runnable = new Runnable() {
        @Override
        public void run() {
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
            if (activefragment == null)

            {
                fragmentTransaction.remove(activefragment);
            } else

            {
                fragmentTransaction.replace(R.id.fragmentContainer, activefragment, activefragment.getTag());
                fragmentTransaction.disallowAddToBackStack();
            }
            fragmentTransaction.commit();

        }
    };
    handler.postDelayed(runnable, timeout);
