我正尝试按照this link并使用Plugin.GoogleClient插件来实现Google身份验证
我已经非常仔细地遵循了所有步骤：sha键，IO上的钥匙链，Auth谷歌协议，Firebase..但是我有2个错误：
关于Andoid：我有错误：Google客户端基础异常
错误：“10：“
在IOS上：我有错误：Google客户端基础异常
错误：“读取或写入应用程序密钥链时出现问题”
按钮通过调用函数“OnLogGoogle”启动验证
下面是代码：

IGoogleClientManager _googleService = CrossGoogleClient.Current; //Plugin.GoogleClient

private async  void OnLogGoogle(object senderApp, EventArgs eApp)
{
    _googleService.OnLogin += OnLoginCompleted;
    try
    {
        await _googleService.LoginAsync();
    }
    catch (GoogleClientSignInNetworkErrorException e)
    {
        await App.Current.MainPage.DisplayAlert("Error1", e.Message, "OK");
    }
    catch (GoogleClientSignInCanceledErrorException e)
    {
        await App.Current.MainPage.DisplayAlert("Error2", e.Message, "OK");
    }
    catch (GoogleClientSignInInvalidAccountErrorException e)
    {
        await App.Current.MainPage.DisplayAlert("Error3", e.Message, "OK");
    }
    catch (GoogleClientSignInInternalErrorException e)
    {
        await App.Current.MainPage.DisplayAlert("Error4", e.Message, "OK");
    }
    catch (GoogleClientNotInitializedErrorException e)
    {
        await App.Current.MainPage.DisplayAlert("Error5", e.Message, "OK");
    }
    catch (GoogleClientBaseException e)
    {
        await App.Current.MainPage.DisplayAlert("Error6", e.Message, "OK");

    } 

}


private void OnLoginCompleted(object sender, GoogleClientResultEventArgs<GoogleUser> loginEventArgs)
        {
            if (loginEventArgs.Data != null)
            {
                GoogleUser googleUser = loginEventArgs.Data;
              /*  User.Name = googleUser.Name;
                User.Email = googleUser.Email;
                User.Picture = googleUser.Picture;
                var GivenName = googleUser.GivenName;
                var FamilyName = googleUser.FamilyName;*/

                // Log the current User email
                Console.WriteLine("email "+ googleUser.Email);
                

                var token = CrossGoogleClient.Current.AccessToken;
                var Token = token;
            }
            else
            {
                App.Current.MainPage.DisplayAlert("Error", loginEventArgs.Message, "OK");
            }

            _googleService.OnLogin -= OnLoginCompleted;

        }
