Facebook Android won't stay logged in between sessions

Hi, I am testing the facebook SDK 7.1.0 with Unity 5 on Android.
I don't have the facebook app installed on the Android device.

I can log in with facebook properly, but every time I kill the app and restart it, I always get FB.IsLoggedIn = FALSE, meaning that I have to display the login dialog again (which tells me "you have already authorized this app").

Am I missing something ? Is anyone else having this problem avec facebook SDK 7.1 on Android?

 

Code (CSharp):

1. public void OnInitComplete()
2.     {
3.         Debug.Log("OnInitComplete Called");
4.        
5.         Debug.Log("Is logged in? " + FB.IsLoggedIn);
6.         if(FB.IsLoggedIn)
7.         {
8.            
9.         }
10.         else
11.         { //TODO
12.             StartCoroutine(CheckFbInit()); //Facebook BUG
13.         }
14.     }
15.  
16.     IEnumerator CheckFbInit()
17.     {
18.         yield return new WaitForSeconds(1f);
19.  
20.             if (FB.IsLoggedIn)
21.             {
22.                 //Here you should be logged in
23.             }
24.         }
25.     }

Try this out. Is a known bug for the. Is logged in turns true after the callback. Hope it helps.

 

same issue with me !

 

I have the same issue on iOS with SDK 7.8 (Unity 5.3.4). I tried the solution suggested by HeritageDevelopment (delayed recheck) but that still doesn't work.

 

I'm using SDK 7.8.0 an it works fine for me. I'm not doing any delays, everything is inside of OnInitComplete.

Something like this....

Code (CSharp):

1. public void Login(Action<bool> callback)
2. {
3.     FB.Init(() =>
4.     {
5.         if (FB.IsLoggedIn)
6.         {
7.             FB.Mobile.RefreshCurrentAccessToken(response => {
8.                 callback(true);
9.             });
10.         }
11.         else
12.         {
13.             callback(false);
14.         }
15.     });
16. }
17.  

 

Problem solved for me, thanks (Unity 5.3.5 p7, Facebook SDK 7.9.4)

 

what is the callback function supposed to do?

 

Whatever you want it to do. If actions are a new thing for you, then read

wasn't the issue. Thought something specific may have to happen in the callback. Ty.
