Unity Facebook SDK for FB Ads Measurement

Question

I want to Facebook SDK Integration for Facebook Mobile Install Ads.

I added to Facebook Unity Plugin. I was completed the FB APP ID, Keyhash etc.

Im using FB Plugin 6.0.

I added to MainMenu.cs FB Init code;

public static void ActivateApp(){
    //FB.Init (true);
    FB.ActivateApp();

}

void Start() {

    ActivateApp ();

//some code.. }

I have error;

NullReferenceException: Facebook object is not yet loaded.  Did you call FB.Init()?
FB.get_FacebookImpl () (at Assets/Facebook/Scripts/FB.cs:28)
FB.ActivateApp () (at Assets/Facebook/Scripts/FB.cs:272)
MenuManager.ActivateApp () (at Assets/Scripts/Menu/MenuManager.cs:48)
MenuManager.Start () (at Assets/Scripts/Menu/MenuManager.cs:63)

Thanks for helping.

You must call FB.Init() first before any other calls. See this page https://developers.facebook.com/docs/javascript/reference/FB.init/v2.3
