How to Integrate Huawei Account kit - unity3d

Question

Currently I'm using Huawei Plugin From EvilMindDev.
Below is AccountManager script.
using HuaweiMobileServices.Id;
using HuaweiMobileServices.Utils;
using System;
using UnityEngine;
namespace HmsPlugin
{
public class AccountManager : MonoBehaviour
{
public static AccountManager GetInstance(string name = "AccountManager") => GameObject.Find(name).GetComponent<AccountManager>();
private static HuaweiIdAuthService DefaultAuthService
{
get
{
Debug.Log("[HMS]: GET AUTH");
var authParams = new HuaweiIdAuthParamsHelper(HuaweiIdAuthParams.DEFAULT_AUTH_REQUEST_PARAM).SetIdToken().CreateParams();
Debug.Log("[HMS]: AUTHPARAMS AUTHSERVICE" + authParams);
var result = HuaweiIdAuthManager.GetService(authParams);
Debug.Log("[HMS]: RESULT AUTHSERVICE"+ result);
return result;
}
}
public AuthHuaweiId HuaweiId { get; private set; }
public Action<AuthHuaweiId> OnSignInSuccess { get; set; }
public Action<HMSException> OnSignInFailed { get; set; }
private HuaweiIdAuthService authService;
// Start is called before the first frame update
void Awake()
{
Debug.Log("[HMS]: AWAKE AUTHSERVICE");
authService = DefaultAuthService;
Debug.Log("DefaultAuthService : "+DefaultAuthService);
Debug.Log("authService : "+authService);
}
public void SignIn()
{
Debug.Log("[HMS]: Sign in " + authService);
authService.StartSignIn((authId) =>
{
HuaweiId = authId;
Debug.Log("HuaweiId : "+HuaweiId);
OnSignInSuccess?.Invoke(authId);
}, (error) =>
{
HuaweiId = null;
OnSignInFailed?.Invoke(error);
});
}
public void SignOut()
{
Debug.Log("authService.SignOut");
authService.SignOut();
HuaweiId = null;
}
}
}
Below is AccountSignIn script.
using HuaweiMobileServices.Id;
using HuaweiMobileServices.Utils;
using UnityEngine;
using UnityEngine.UI;
using HmsPlugin;
public class AccountSignIn : MonoBehaviour
{
private const string NOT_LOGGED_IN = "No user logged in";
private const string LOGGED_IN = "{0} is logged in";
private const string LOGIN_ERROR = "Error or cancelled login";
private Text loggedInUser;
private AccountManager accountManager;
// Start is called before the first frame update
void Start()
{
loggedInUser = GameObject.Find("LoggedUserText").GetComponent<Text>();
loggedInUser.text = NOT_LOGGED_IN;
//accountManager = AccountManager.GetInstance();
accountManager = GetComponent<AccountManager>();
accountManager.OnSignInSuccess = OnLoginSuccess;
accountManager.OnSignInFailed = OnLoginFailure;
LogIn();
}
public void LogIn()
{
accountManager.SignIn();
}
public void LogOut()
{
accountManager.SignOut();
loggedInUser.text = NOT_LOGGED_IN;
}
public void OnLoginSuccess(AuthHuaweiId authHuaweiId)
{
loggedInUser.text = string.Format(LOGGED_IN, authHuaweiId.DisplayName);
}
public void OnLoginFailure(HMSException error)
{
loggedInUser.text = LOGIN_ERROR;
}
}
Everytime I try to SignIn it will give me this error.
This is HuaweiIdAuthService.
Even if I try the demo provided will give me the same error.
If I try debug using Android Studio it will still give me the same error.
public void SignIn()
{
Debug.Log("[HMS]: Sign in " + authService);
authService.StartSignIn((authId) =>
{
HuaweiId = authId;
Debug.Log("HuaweiId : "+HuaweiId);
OnSignInSuccess?.Invoke(authId);
}, (error) =>
{
HuaweiId = null;
OnSignInFailed?.Invoke(error);
});
}
the authService doesn't return anything. Where can I get that from ?

Answer 1

It is a null pointer. Please check for unassigned objects. If you cannot find anything, please delete project and install again cause sometimes these kind of things happening.

Answer 2

This plugin have 2 branch for Unity 2019 and Unity 2018.
You should activate Account Kit API in Huawei Appgallery
Check configuration AndroidManifest file
Check Agconnect-service.json file
