Android invalidateOptionsMenu() for API < 11
ActivityCompat.invalidateOptionsMenu() doesn't callback onPrepareOptionsMenu(); it just update the menu directly. Just put some Log.d() and check out by yourself.
This works for me (I'm using API 8):
private Menu mMenu;@Overridepublic void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { inflater.inflate(R.menu.track_fragment, menu); mMenu = menu; }...private void someMethod() {... if (mMenu != null) { MenuItem item = mMenu.findItem(R.id.new_track); if (item != null) { item.setVisible(false); ActivityCompat.invalidateOptionsMenu(this.getActivity()); } }...}My someMethod() get called from several places, even before onCreateOptionsMenu(), so I must check mMenu != null.
