title: How do you use multiple FB Application IDs within single client using FB SDK 4?
body: <p>In versions 3.X of the FB SDK for Android and iOS you could create and open multiple com.facebook.Session objects for different Facebook Application IDs within the same iOS or Android app. This is useful when your mobile app needs to interact with multiple Facebook Apps.</p>
  
  <p>Version 4.X of the FB SDK appears to only allow a shared singleton instance to be initialized with a single FB APP ID, thus preventing a single client from accessing multiple FB APPs</p>
  
  <p>Has anyone found a way to support this?</p>
