Unity 2017，燃烧4.2.App在Unity编辑器中工作，但是在Android上运行该应用程序时失败.fireb

Question

我正在研究Unity 2017.2.0f3和firebase SDK 4.2.1当我在Unity编辑器环境中运行PC时，它可以正常工作，当我将其构建到APK并在Android上运行它时设备，firebase给我一个错误。

我的代码：

    FirebaseApp.DefaultInstance.SetEditorP12FileName("xxxxxxxxxxxxxxx-admin-sdk.p12"); 
 FirebaseApp.DefaultInstance.SetEditorServiceAccountEmail("xxxxxxxxxxxxxxx.iam.gserviceaccount.com"); 
    FirebaseApp.DefaultInstance.SetEditorP12Password("notasecret");
    FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task => {
    dependencyStatus = task.Result;
    if (dependencyStatus == DependencyStatus.Available) {
    InitializeFirebase();
    } else {
    Debug.LogError(
    "Could not resolve all Firebase dependencies: " + dependencyStatus);
    }
    });

我正在使用服务帐户来连接，在我运行该应用程序时，它在Unity编辑器上的工作非常完美。但是，当我生成APK并将其安装在Android设备（Samsung S7，Android 7.0）上时，当我运行应用程序时，LogCat会给我这个错误：

11-22 21:23:58.819: E/Unity(5835): Firebase.Database.Internal.Core.ValueEventRegistration:FireCancelEvent(DatabaseError)
11-22 21:23:58.819: E/Unity(5835): Firebase.Database.Internal.Core.View.CancelEvent:Fire()
11-22 21:23:58.819: E/Unity(5835): Firebase.Database.Internal.Core.View.Runnable30:Run()

在此链接上还报告了错误：https：//github.com/firebase/quickstart-unity/issues/120

欢迎任何帮助..

好吧...我犯了夫妇错误，终于解决了。由于某种原因，还不足以在您的项目上设置服务帐户，可以从Firebase实时数据库读取/编写数据。运行游戏时，它可以在Unity编辑器上使用。但是，当您在移动设备（Android）上符合APK时，App（Game）必须验证有效的firebase用户

我在Firebase控制台上创建了一个用户签名方法电子邮件/密码。然后，我使用Firabase Authetication Unity软件包在5月应用程序上进行了身份验证，瞧，...它有效。当用户在firebase上进行身份验证时，firebase系统会自动将实时数据库规则更改为true

{
  "rules": {
    ".read": "auth != null",
    ".write": "auth != null"
  }
}

我的工作代码，即使在Unity编辑器和移动设备上也是如此：

private Firebase.Auth.FirebaseAuth auth;
private Firebase.Auth.FirebaseUser newUser;
void Awake() {
    //Using Firebase SDK
    //This is needed only for the unity editor
    FirebaseApp.DefaultInstance.SetEditorP12FileName("xxxxxxxxxxxxxxxxxxx-admin-sdk.p12");
    FirebaseApp.DefaultInstance.SetEditorServiceAccountEmail("[e-mail]");
    FirebaseApp.DefaultInstance.SetEditorP12Password("notasecret");
    //--------------------------------------
    FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task => {
        dependencyStatus = task.Result;
        if (dependencyStatus == DependencyStatus.Available) {
            InitializeFirebase();
        } else {
            Debug.LogError(
              "Could not resolve all Firebase dependencies: " + dependencyStatus);
        }
    });
}
// Initialize the Firebase database:
protected virtual void InitializeFirebase() {
    FirebaseApp app = FirebaseApp.DefaultInstance;
    // NOTE: You'll need to replace this url with your Firebase App's database
    // path in order for the database connection to work correctly in editor
    //This is needed only for the unity editor
    app.SetEditorDatabaseUrl("https://xxxx.yyyyyyyyy.com/");
    if (app.Options.DatabaseUrl != null) app.SetEditorDatabaseUrl(app.Options.DatabaseUrl);
    //--------------------------------------
    Firebase.Auth.FirebaseAuth auth = Firebase.Auth.FirebaseAuth.DefaultInstance;
    auth.SignInWithEmailAndPasswordAsync("[e-mail]", "strongpassword").ContinueWith(task => {
        if (task.IsCanceled) {
            Debug.LogError("SignInWithEmailAndPasswordAsync was canceled.");
            return;
        }
        if (task.IsFaulted) {
            Debug.LogError("SignInWithEmailAndPasswordAsync encountered an error: " + task.Exception);
            return;
        }
        Firebase.Auth.FirebaseUser newUser = task.Result;
        Debug.LogFormat("User signed in successfully: {0} ({1})",
            newUser.DisplayName, newUser.UserId);
        //Getting client id for FB using device id
        FirebaseDatabase.DefaultInstance.GetReference("node1").Child(node2).Child("node3")
        .ValueChanged += HandleChanged;
    });
}

注意：密码应该很强。不要忘记在销毁方法上进行登录，否则下次尝试连接时会出现错误。

auth.SignOut();
