How to check that options menu is opened? (menu in actionbar, or menu from preference button in older devices) There is some method for this?

Have a look at this SO question :
How do I programmatically check if the menu of my activity is showing at a particular moment?
Not a proper solution but the best workaround possible at the moment.
