title: In-App purchase for widget Android Billing Version 3
body: <p>I am looking to restrict access to a new widget I have added to one of my Android apps, so that it is available as an In-App purchase.
  Is there a way to check to see if the widget as been purchased and if not the stop the user from being able to use it?</p>
  
  <p>I can easily query items in Activity classes but in the AppWidgetProvider I am struggling to get there.</p>
  
  <p>If it is possible, could you provide either a link or some sample code to nudge me in the right direction.</p>
