title: Login and list Facebook friends using Social Framework
body: <p>Could someone give me some pointers on how to integrate this? my goal is to get list of friends who installed my app (fb app). initially I need to login user to my app first and list friends who have / haven't installed the app. </p>
  
  <p>PS : I don't want to use Facebook SDK. I had nightmares in the past due to facebook did countless time changing the sdk.</p>
  
  <p>===========
  UPDATE</p>
  
  <p>I've successfully login and list my facebook friends. But now problem to list my friend who have the app and list picture as well. I tried this :</p>
  
  <p>URL : <a href="https://graph.facebook.com/me/friends?friends?fields=id,name,installed,picture" rel="nofollow">https://graph.facebook.com/me/friends?friends?fields=id,name,installed,picture</a></p>
  
  <p>which give me <code>OAuthException : An active access token must be used to query information about the current user.</code> problem. </p>
  
  <p>I tried also in <a href="https://developers.facebook.com/tools/explorer?method=GET&amp;path=me/friends?fields=id,name,%20installed,picture" rel="nofollow">API Graph</a>, it works without mentioned error.</p>
  
  <p>if I try only <code>me/friends</code> works perfectly, it will list down all my friends. </p>
