        // Locate MenuItem with ShareActionProvider
         MenuItem item = menu.findItem(R.id.menu_share);

CreateSharedActionprovider takes a Menu as argument, but you're calling it without any arguments. Looks like your Menu is null and you are trying to call findItem on it.

I tried using Menu as an arguement too but still nothing....Could you tell me how to do it – user2429689 Jul 14 '13 at 21:19
You need to create a menu object and pass it in from onCreate(). http://developer.android.com/guide/topics/ui/menus.html has a nice overview. – Jul 14 '13 at 21:26
I read it...Actually the app use camera via Intent and when user takes picture and return to UI of my app I want that shareactionprovider should be available so obviously i want it to be called from onCreate()...How to call the method CreateSharedActionprovider()..Could you give a bit of code please – user2429689 Jul 15 '13 at 19:31
I'm sorry, I'm confused. This has nothing to do with the camera. On initialization, in onCreate, you need to instantiate your menu. Then you can pass it to CreatedSharedActionprovider. http://developer.android.com/guide/topics/ui/menus.html is about as clear as it gets. – Jul 15 '13 at 19:41
