when the app is running, and i press home-key, open setting, change locale language, select my running app from recently app list, the option menu in actionbar will increase duplicate menuitem, what's happen?

Gemini, I know it is late and you most probably have the answer already. The easiest way to fix this issue is to just add menu.clear();

public void onPrepareOptionsMenu(Menu menu) {
  MenuInflater inflater = new MenuInflater(getActivity().getApplicationContext());

  menu.clear();

  super.onPrepareOptionsMenu(menu);
  inflater.inflate(R.menu.myMenu, menu);
}
