c# – Unity Firebase中的InitializationException

SHA-1密钥是使用keytool生成的,并添加到控制台中的Firebase项目中.

google-services.json也被添加到Assets文件夹中.

初始化Firebase的简单脚本：

DependencyStatus dependencyStatus = DependencyStatus.UnavailableOther;
// Use this for initialization
void Start () 
{
    Debug.Log ("Start FireBase");
    dependencyStatus = FirebaseApp.CheckDependencies();

    if (dependencyStatus != DependencyStatus.Available) 
    {
        FirebaseApp.FixDependenciesAsync().ContinueWith(task => 
        {
            dependencyStatus = FirebaseApp.CheckDependencies();
            if (dependencyStatus == DependencyStatus.Available) 
            {
                InitializeFirebase();
            } 
            else 
            {
                Debug.LogError("Could not resolve all Firebase dependencies: " + dependencyStatus);
            }
        });
    } 
    else 
    {
        InitializeFirebase();
    }
}

void InitializeFirebase() 
{
    FirebaseAnalytic.Instance().setAnalyticsCollectionEnabled(true);
    FirebaseAnalytic.Instance().setUserProperty(FirebaseAnalytics.UserPropertySignUpMethod,"Google");
    FirebaseAnalytic.Instance().setUserId(SystemInfo.deviceUniqueIdentifier);
    FirebaseAnalytic.Instance().logEvent("LogIn",FirebaseAnalytics.EventLogin);
    Debug.Log ("FirebaseAnalytics Logined");
}

所以应用程序构建和运行没有崩溃.但通过adb logcat -s Unity我可以看到以下内容：

谷歌搜索任何这些消息都没有多大帮助.我错过了什么？
我一步一步地遵循了针对Unity的Firebase安装教程.这个错误已经让我恐惧了一个星期了！
