问题

我正在获取有关Firebase分析的数据，但无法使crashlytics报告任何内容。我卡在这个...

重现步骤：

• 添加Firebase Analytics和crashlytics SDK。

• 将google-services.json GoogleService-Info.plist文件添加到资产文件夹中的某处

• 添加此代码以初始化firebase

        // Use this for initialization
    void Start ()
    {
    // Initialize Firebase
    Firebase.FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task => {
    var dependencyStatus = task.Result;
    if (dependencyStatus == Firebase.DependencyStatus.Available)
    {
    // Create and hold a reference to your FirebaseApp,
    // where app is a Firebase.FirebaseApp property of your application class.
    // Crashlytics will use the DefaultInstance, as well;
    // this ensures that Crashlytics is initialized.
    Firebase.FirebaseApp app = Firebase.FirebaseApp.DefaultInstance;
  
                // Set a flag here for indicating that your project is ready to use Firebase.
                VisualDebugger.SetText("crashlytics initialised");
            }
            else
            {
                UnityEngine.Debug.LogError(System.String.Format(
                  "Could not resolve all Firebase dependencies: {0}",dependencyStatus));
  
                VisualDebugger.SetText("crashlytics NOT initialised: " + dependencyStatus);
                // Firebase Unity SDK is not safe to use here.
            }
        });
  
        Invoke("IsCrashEnabled", 5f);
    }
  
    void IsCrashEnabled()
    {
        VisualDebugger.AddLine("IsCrashlyticsCollectionEnabled: "+Firebase.Crashlytics.Crashlytics.IsCrashlyticsCollectionEnabled);
    }
  

为了使该应用程序在安装了Facebook sdk的情况下运行，Ive在Proguard-user.txt中添加了这两行

 -keep public class com.facebook.**{public *; } 
 -keep public class com.facebook.internal.**{ public *; }

并从mainTemplate.gradle中注释掉以下几行

    //implementation 'com.android.support:appcompat-v7:25.3.1' // Facebook.Unity.Editor.AndroidSupportLibraryResolver.addSupportLibraryDependency
    //implementation 'com.android.support:customtabs:25.3.1' // Facebook.Unity.Editor.AndroidSupportLibraryResolver.addSupportLibraryDependency
    //implementation 'com.android.support:support-v4:25.3.1' // Facebook.Unity.Editor.AndroidSupportLibraryResolver.addSupportLibraryDependency

当我运行该应用程序时，firebase已成功初始化。Firebase.Crashlytics.Crashlytics.IsCrashlyticsCollectionEnabled也会返回true。

我以多种不同的方式使应用程序崩溃，然后再次打开它而无需重新安装。但没有发送崩溃报告。

当我在启动应用程序时观看logcat时，每次打开应用程序时，我都会从firebase中看到此错误
