title: Access token removed in Facebook Android SDK 4.0
body: <p>I am using Facebook Android SDK 4.0 (newly updated version). I logged in to my app after the initial setup. Then I exited from my app. If again start my app, user is not in the logged in state. When I use debugger, it shows "ACCESS TOKEN REMOVED". What is the procedure to check whether the user is in logged in state using Access Token? </p>
  
  <p>I have tried new log in method (according to newer version 4.0) in which they mentioned about log in process. I have done it. But whenever I open up Access Token state is "ACCESS TOKEN REMOVED". I checked App id, Package name, Activity name in dash board settings. All are correct. Help me to find solution for this problem.</p>
