Facebook SDK login issue

[gajdot]

Hi, I just installed the new version of Unity 4.3 and the new facebook sdk and I can’t get it working.

I created the app on facebook, copied over the app id to the unity facebook settings as required and copied the Package Name and Class name back to facebook.

Because the Android Key Hash is empty ( even it shouldn’t be ) I used the methods posted by others to create one with openssl. I created it and copied over to facebook as required.

After this I created a small script to be able to login.

// Use this for initialization
void Start () {
	enabled = false;                  
	FB.Init(SetInit, OnHideUnity);  
}

// Update is called once per frame
void Update () {

}

private void SetInit()                                                                       
{                                                                                            
	FbDebug.Log("SetInit");                                                                  
	enabled = true; // "enabled" is a property inherited from MonoBehaviour                  
	if (FB.IsLoggedIn)                                                                       
	{                                                                                        
		FbDebug.Log("Already logged in");                                                    
		OnLoggedIn();

{                                                                                          
	FbDebug.Log("Logged in. ID: " + FB.UserId);                                            
} 

Now when I click on the login button a Facebook window appears requesting permission, after I press ok, it returns, but I’m still not logged in… Can anybody help why is this?
Another strange thing I observed that the LoginCallback gets called as soon as I click on the login button, even though I would think it should only when I gave permission. Anyway when I give permission it returns to my app and nothing happens. I can click on the login button again and same thing happens, login callback called, it asks for permisions, I give the permision and returns back, nothing happened. Can anybody help?

Edit:
Sdk version: 4.3.4
Unity version: 4.3.0f4

I tried the example in the examples folder and even that isn’t working. Even if it seems that I can log in, it even requests permissions, when it returns to the unity scene it says LoggedIn false

I am not sure where that hash came from in logcat but I cut and pasted it into my facebook developer page for the app as an additional hash and now everything works.

We were having the same problem. We found the answer here.

It turned out we were using the wrong openssl
