Unity, Facebook SDK, in Android build the app crashes

I am integrating Unity Facebook SDK to a project, right now I am making a log-in system. I have written a script, attached it to an object on a scene, created a button, added the FbLogin method as a listener of OnClick UnityEvent of my button and built an app for Android. Also I have pasted all the needed keys and tokens.
using System.Collections.Generic;
using UnityEngine;
using Facebook.Unity;
class FacebookLoginSystem
{
private void Awake()
{
FB.Init(SetInit, OnHideUnity);
}
void SetInit()
{
if (FB.IsLoggedIn)
{
Debug.Log("Logged in Successfuly!");
}
else
{
Debug.Log("FB is not loggid in");
}
}
void OnHideUnity(bool isGameShown)
{
if (isGameShown)
{
Time.timeScale = 1;
}
else
{
Time.timeScale = 0;
}
}
public void FbLogin()
{
List<string> permessions = new List<string>();
permessions.Add("public_profile");
FB.LogInWithReadPermissions(permessions, AuthCallResult);
}
private void AuthCallResult(ILoginResult result)
{
if (result.Error != null)
{
Debug.Log(result.Error);
}
else
{
if (FB.IsLoggedIn)
{
Debug.Log("FB logged in");
Debug.Log(result.RawResult);
FB.API("/me?fields=first_name", HttpMethod.GET, callbackData);
}
else
{
Debug.Log("Login Failed!");
}
}
}
}
But when I press the button in my build, I get this. ("Something went wrong, we are working on it...")
Tell me, please, why does it happen?
This happens when I press the button
UPD:
I have replaced the methods FbLogin and AuthCallback with these versions. Also I added a serialized field TextForLogging to see my logs in Build, and it tells me that "User cancelled login".
public void FbLogin()
{
var perms = new List<string>() { "public_profile", "email" };
FB.LogInWithReadPermissions(perms, AuthCallback);
}
private void AuthCallback(ILoginResult result)
{
if (FB.IsLoggedIn)
{
// AccessToken class will have session details
var aToken = Facebook.Unity.AccessToken.CurrentAccessToken;
// Print current access token's User ID
Debug.Log(aToken.UserId);
TextForLogging.text += $"\n{aToken.UserId}";
// Print current access token's granted permissions
foreach (string perm in aToken.Permissions)
{
Debug.Log(perm);
TextForLogging.text += $"\n{perm}";
}
FB.API("/me?fields=first_name", HttpMethod.GET, callbackData);
}
else
{
Debug.Log("User cancelled login");
TextForLogging.text += "\nUser cancelled login";
}
}

Unity IAP | In App Purchase | Unknown Error

I want to implement IAP in my android game.
This is my code, it is from the official unity website:
using System;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Purchasing;
using UnityEngine.UI;
public class Purchaser : MonoBehaviour, IStoreListener {
private static IStoreController m_StoreController; // The Unity Purchasing system.
private static IExtensionProvider m_StoreExtensionProvider; // The store-specific Purchasing subsystems.
public Text text;
public static string kProductIDConsumable = "pile_shadycoin";
void Start() {
if (m_StoreController == null) {
InitializePurchasing();
}
}
public void InitializePurchasing() {
if (IsInitialized()) {
return;
}
var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
builder.AddProduct(kProductIDConsumable, ProductType.Consumable);
UnityPurchasing.Initialize(this, builder);
}
private bool IsInitialized() {
return m_StoreController != null && m_StoreExtensionProvider != null;
}
public void BuyConsumable() {
BuyProductID(kProductIDConsumable);
}
void BuyProductID(string productId) {
if (IsInitialized()) {
Product product = m_StoreController.products.WithID(productId);
if (product != null && product.availableToPurchase) {
text.text = "Purchasing product asychronously: '{0}'";
m_StoreController.InitiatePurchase(product);
} else {
text.text = "BuyProductID: FAIL. Not purchasing product, either is not found or is not available for purchase";
}
} else {
text.text = "BuyProductID FAIL. Not initialized.";
}
}
public void OnInitialized(IStoreController controller, IExtensionProvider extensions) {
text.text = "OnInitialized: PASS";
m_StoreController = controller;
m_StoreExtensionProvider = extensions;
}
public void OnInitializeFailed(InitializationFailureReason error) {
text.text = "OnInitializeFailed InitializationFailureReason:" + error;
}
public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs args) {
if (String.Equals(args.purchasedProduct.definition.id, kProductIDConsumable, StringComparison.Ordinal)) {
text.text = "ProcessPurchase: PASS. Product: '{0}'";
} else {
text.text = "ProcessPurchase: FAIL. Unrecognized product: '{0}'";
}
return PurchaseProcessingResult.Complete;
}
public void OnPurchaseFailed(Product product, PurchaseFailureReason failureReason) {
text.text = failureReason + "";
}
}
I am using the consumable item pile_shadycoin.
In the picture you can see the id and that it's active (it's german)
Picture of Google Play
If I build my project and put it on my smartphone and press the button, which is linked to BuyConsumable() it opens the menu and says:
Fehler Der angeforderte Artikel kann nicht gekauft werden
In English:
Error The requested item cannot be purchased

I found my error. I didn't released the build on alpha or beta.
I pulled the APK directly to my phone.

Firebase authentication via google play games

I would like to use authentication via google play games but always after second login or linking request(first was successful) a got:
Firebase.FirebaseException: An internal error has occurred. [ Error getting access token from GOOGLE_PLAY_GAMES, OAuth2 redirect uri is:http://localhost, response: OAuth2TokenResponse{params: error=invalid_grant&error_description=Bad%20Request, httpMetadata: HttpMetadata{status=400, cachePolicy=NO_CACHE, cacheDuration=null, cacheImmutable=false, staleWhileRevalidate=null, filename=null, lastModified=null, headers=HTTP/1.1 200 OK, cookieList=[]}} ]
When I delete a user, the login works correctly again.
Should I set something in firebase console to solve this problem?
Auth to GPG scripts:
public void Init()
{
PlayGamesHelperObject.CreateObject();
PlayGamesHelperObject.RunOnGameThread(() =>
{
PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder()
.RequestServerAuthCode(false)
.Build();
PlayGamesPlatform.DebugLogEnabled = true;
PlayGamesPlatform.InitializeInstance(config);
Social.Active = PlayGamesPlatform.Activate();
});
}
public void Authenticate(Action<bool, ILocalUser, string> onAuth)
{
if (Social.localUser == null)
{
onAuth.Invoke(false, Social.localUser, string.Empty);
return;
}
if (Social.localUser.authenticated)
{
onAuth.Invoke(true, Social.localUser, PlayGamesPlatform.Instance.GetServerAuthCode());
return;
}
PlayGamesHelperObject.RunOnGameThread(() =>
{
Social.Active.Authenticate(Social.localUser, (status)=>
{
onAuth.Invoke(status, Social.localUser, PlayGamesPlatform.Instance.GetServerAuthCode());
});
});
}
On Auth Invoke:
private FirebaseUser User { get; set; }
private GoogleAuth Auth { get; set; }
event Action<Exception> onSingInFailed = delegate { };
event Action<FirebaseUser> onSignInSocials = delegate { };
event Action<FirebaseUser> onLinkInSocials = delegate { };
public void OnSocialsLogin(bool status, ILocalUser user, string authCode)
{
if(status)
{
Credential credential = PlayGamesAuthProvider.GetCredential(authCode);
if (User == null)
Auth.SignInWithCredential(credential, onSignInSocials, onSingInFailed);
else
Auth.LinkWithCredential(User, credential, onLinkInSocials, (exc) =>
{
onLinkFailed.Invoke(exc);
Auth.SignInWithCredential(credential, onSignInSocials, onSingInFailed);
});
}
}
Part of GoogleAuth class:
private static FirebaseAuth Auth { get; set; }
public void SignInWithCredential(Credential credential, Action<FirebaseUser> onSignIn, Action<Exception> onFailure, Action onCanceled = default(Action))
{
if (onCanceled == null)
onCanceled = delegate { };
Auth.SignInWithCredentialAsync(credential).ContinueWith(task =>
{
if (task.IsCanceled)
onCanceled.Invoke();
else if (task.IsFaulted)
onFailure.Invoke(task.Exception);
else if (task.IsCompleted)
onSignIn.Invoke(task.Result);
});
}
public void LinkWithCredential(FirebaseUser user, Credential credential, Action<FirebaseUser> onLinkIn, Action<Exception> onFailure, Action onCanceled = default(Action))
{
if (onCanceled == null)
onCanceled = delegate { };
user.LinkWithCredentialAsync(credential).ContinueWith(task =>
{
if (task.IsCanceled)
onCanceled.Invoke();
else if (task.IsFaulted)
onFailure.Invoke(task.Exception);
else if (task.IsCompleted)
onLinkIn.Invoke(task.Result);
});
}

trouble integrating facebook into a unity android project

I've been trying to integrate facebook into my project and I've successfully managed to do just that with the help of some online tutorials however I do have one persisting problem...
The code is set to pause the game using
Time.timescale = 0; when a facebook window is up and to resume play using Time.timescale = 1; when it's not
but that just doesn't happen, and the function that pauses the game never gets called...
Here's the code :
using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using System.Collections.Generic;
public class FBHolder : MonoBehaviour {
public GameObject UIFBIsLoggedIn;
public GameObject UIFBNotLoggedIn;
public GameObject UIFBAvatar;
public GameObject UIFBUserName;
public GameObject ScoreEntryPanel;
public GameObject ScoreScrollList;
private List<object> scoreslist = null;
private Dictionary<string, string> profile = null;
void Awake()
{
FB.Init (SetInit, onHideUnity);
}
private void SetInit()
{
Debug.Log ("FB Init Done");
if(FB.IsLoggedIn)
{
Debug.Log ("FB Logged In");
managefbmenus(true);
}
else
{
managefbmenus(false);
}
}
private void onHideUnity(bool isGameShown)
{
if(!isGameShown)
{
Debug.Log ("Pause Game");
Time.timeScale = 0;
}
else
{
Time.timeScale = 1;
}
}
public void FBLogin()
{
FB.Login ("email,publish_actions", Authcallback);
}
void Authcallback(FBResult result)
{
if(FB.IsLoggedIn)
{
Debug.Log ("FB Login Worked");
managefbmenus(true);
}
else
{
Debug.Log ("FB Login Failed");
managefbmenus(false);
}
}
void managefbmenus(bool isLoggedIn)
{
if(isLoggedIn)
{
UIFBIsLoggedIn.SetActive(true);
UIFBNotLoggedIn.SetActive(false);
SetScore();
//Get profile picture
FB.API(Util.GetPictureURL("me", 128, 128), Facebook.HttpMethod.GET, DealWithProfilePicture);
FB.API("/me?fields=id,first_name", Facebook.HttpMethod.GET,DealwithUserName);
//Get username
}
if(!isLoggedIn)
{
UIFBIsLoggedIn.SetActive(false);
UIFBNotLoggedIn.SetActive(true);
}
}
void DealWithProfilePicture(FBResult result)
{
if(result.Error != null)
{
Debug.Log ("Problem getting profile picture");
FB.API(Util.GetPictureURL("me", 128, 128), Facebook.HttpMethod.GET, DealWithProfilePicture);
return;
}
Image UserAvatar = UIFBAvatar.GetComponent<Image> ();
UserAvatar.sprite = Sprite.Create (result.Texture, new Rect(0, 0, 128, 128), new Vector2(0, 0));
}
void DealwithUserName(FBResult result)
{
if(result.Error != null)
{
Debug.Log ("Problem getting username");
FB.API("/me?fields=id,first_name", Facebook.HttpMethod.GET,DealwithUserName);
return;
}
profile = Util.DeserializeJSONProfile(result.Text);
Text UserMsg = UIFBUserName.GetComponent<Text>();
UserMsg.text = "Hello, " + profile ["first_name"];
}
Any ideas on what could be causing this issue?
BTW: I'm using unity 5.

I guess you don't need to pause your game while Facebook UI is displayed. you can just call it as:
FB.Init(SetInit);

Facebook SDK on Unity cant get anything except first_name

so here is my code for connecting and getting the values:
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using Facebook;
using SmartLocalization;
public class mainMenuFacebook : MonoBehaviour {
public string FBname;
public string FBsurname;
Dictionary<string, string> profile = new Dictionary<string, string>();
// Use this for initialization
void OnMouseDown()
{
FB.Login("publish_actions,public_profile", LoginCallback); // logine tıklama
}
void Awake() {
FB.Init(SetInit, OnHideUnity); //facebook başlangıcı
}
private void SetInit()
{
if (FB.IsLoggedIn)
{
// Util.Log("Already logged in");
OnLoggedIn();
}
}
private void OnHideUnity(bool isGameShown)
{
if (!isGameShown)
{
// pause the game - we will need to hide
Time.timeScale = 0;
}
else
{
// start the game back up - we're getting focus again
Time.timeScale = 1;
}
}
void LoginCallback(FBResult result)
{
Util.Log("LoginCallback");
if (FB.IsLoggedIn)
{ gameObject.guiTexture.enabled = false;
OnLoggedIn();
}
}
void OnLoggedIn()
{
FB.API("/me?fields=first_name,last_name,email", Facebook.HttpMethod.GET, APICallback); // adını ve idyi çekiyoruz.
}
void APICallback(FBResult result)
{
if (result.Error != null)
{
// Let's just try again
// FB.API("/me?fields=id,first_name,last_name,email,friends.limit(100).fields(first_name,last_name,id)", Facebook.HttpMethod.GET, APICallback);
return;
}
Debug.Log(result.Text);
profile = Util.DeserializeJSONProfile(result.Text);
FBname = profile["first_name"];
FBsurname = profile["last_name"]; // **IT GIVES ERROR**
Debug.Log(FBsurname + " " + FBname);
//PlayerPrefs.SetString("surname",profile["last_name"]);
//PlayerPrefs.SetString("email",profile["email"]);
gameObject.guiTexture.enabled = false;
GameObject.Find("Wellcome").guiText.enabled = true;
GameObject.Find("Wellcome").guiText.text = LanguageManager.Instance.GetTextValue("menu.hosgeldin") + " <b><color=#ffa500ff>" + FBname + "</color></b>, <i>" + LanguageManager.Instance.GetTextValue("menu.cikis") +"</i>";
PlayerPrefs.SetString("name",FBname);
}
}
when i only try to get first_name everything is okay. But i need to get last_name and email too. I think i cant serialize because when i try to Debug.Log(profile.Count); it shows 1.
How can i fix it?
Given error is:
KeyNotFoundException: The given key was not present in the dictionary.
System.Collections.Generic.Dictionary`2[System.String,System.String].get_Item (System.String key) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System.Collections.Generic/Dictionary.cs:150)
mainMenuFacebook.APICallback (.FBResult result) (at Assets/Scripts/mainMenuFacebook.cs:84)
Facebook.AsyncRequestString+<Start>c__Iterator0.MoveNext ()

Try this:
public void OnMouseDown()
{
List<string> permissions = new List<string>() { "public_profile", "email" };
FB.LogInWithReadPermissions(permissions,AuthCallback);
Debug.Log("Facebook Login");
}
In AuthCallback: if user logs in successfully, get info from FB api.
private void AuthCallback(ILoginResult result)
{
if(FB.IsLoggedIn)
{
GetInfo();
}
else
{
Debug.Log("User cancelled login");
}
}
FB API returns json result, so you will need FacebookUser class to deserialize it.
class FacebookUser
{
public string id;
public string first_name;
public string last_name;
public string email;
}
public void GetInfo()
{
FB.API("/me?fields=id,first_name,last_name,email", HttpMethod.GET, result =>
{
if(result.Error != null)
{
Debug.Log("Result error");
}
var facebookUser = Newtonsoft.Json.JsonConvert.DeserializeObject<FacebookUser>(result.RawResult);
Debug.Log(" facebook id - " + facebookUser.id);
Debug.Log(" facebook first name - " + facebookUser.first_name);
Debug.Log(" facebook last name - " + facebookUser.last_name);
Debug.Log(" facebook email - " + facebookUser.email);
});
}
NOTE: You should have Email permission from facebook to access it.
Check it in Graph API Explorer
