Unity Firebase黑屏

Question

我正在为Android开发Unity项目。当我构建并运行该应用时，该应用在Unity启动屏幕之后进入黑屏。

如果我禁用了从Firebase下载URL的脚本，则该应用程序将完美运行。

只有具有下载脚本的场景存在此问题，所有其他场景运行良好。

这是用于下载图像和音频的URL的脚本。

 void Start()
{
    Firebase.FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task => {
        var dependencyStatus = task.Result;
        if (dependencyStatus == Firebase.DependencyStatus.Available)
        {
            // Set a flag here indiciating that Firebase is ready to use by your
            // application.
        }
        else
        {
            UnityEngine.Debug.LogError(System.String.Format(
              "Could not resolve all Firebase dependencies: {0}", dependencyStatus));
        }
    });

    //URL to Firebase Database
    FirebaseApp.DefaultInstance.SetEditorDatabaseUrl("https://fir-web-login-f0757.firebaseio.com/");

    // Get the root reference location of the database.
    DatabaseReference reference = FirebaseDatabase.DefaultInstance.RootReference;

    //Data snapshot to store query
    DataSnapshot _data;

    //Query entire database and store in variable;
    reference.OrderByKey().LimitToFirst(100).GetValueAsync().ContinueWith(task =>
    {
        if (task.IsFaulted)
        {
            //Handle error
        }
        else if (task.IsCompleted)
        {
            //Data snapshot of database
            _data = task.Result;

            //Each course in database
            foreach (DataSnapshot d in _data.Children)
            {
                //Each hole in course
                foreach(DataSnapshot e in d.Children)
                {
                    //Each section of the course    
                    foreach(DataSnapshot h in e.Children)
                    {
                        //Each URL
                        foreach(DataSnapshot u in h.Children)
                        {
                            //Each folder(image or audio)
                            foreach (DataSnapshot c in u.Children)
                            {
                                //If the key is "image"
                                if (c.Reference.Parent.Key.Equals("image"))
                                {
                                    //Write value of DB entry to ArrayList
                                    GameMaster.m_holes.Add(c.Value);
                                }
                                //If the key is "audio"
                                if (c.Reference.Parent.Key.Equals("audio"))
                                {
                                    //Write value of DB entry to ArrayList
                                    GameMaster.m_audio_files.Add(c.Value);
                                }
                            }
                        }
                    }
                }
            }
        }
    });

我也有这个问题， 您只需要在第一个场景中一次初始化firebase SDK和ech服务。

确保不要多次初始化Firebase SDK和服务。
