android - 记录事件 (FE) : app_exception(_ae), Bundle[{firebase_event_origin(_o)=crash

Question

我有一个应用程序，里面有很多 Activity ，其中一些连接到 Firebase 数据库。最近，当我去到有 Firebase 调用的 Activity 和之前的 Activity 时，我开始遇到崩溃。应用程序崩溃后，它会重新启动，然后正常运行。所以只有在我通过 USB 安装它之后它才会这样做。发生崩溃时 Logcat 显示:

1-17 21:47:38.030 10998-11021/packagename D/FA: Logging event (FE): app_exception(_ae), Bundle[{firebase_event_origin(_o)=crash, timestamp=1516222057770, fatal=1}]

01-17 21:47:39.702 24162-10793/? V/FA-SVC: Background event processing time, ms: 412

引起我注意的部分是:

Logging event (FE): app_exception(_ae), bundle[{firebase_event_origin(_o)=crash

但是，我不知道如何处理它...很明显它来自 Firebase，但具体来自哪里？

包含 Firebase 脚本的 Java 文件如下:

阅读此错误后here ，我看到有人提示可能是字符长度的问题，但我无法弄清楚这是不是我的问题。我的数据库中不会超过 40 个字符。

Firebase 上的数据库配置如下图所示:

错误是一个模糊的错误，我真的不知道从哪里开始。谁能帮我？谢谢!

您显示的日志并不是因为您的应用当时崩溃了。这是 Google Analytics for Firebase 记录您的应用程序之前崩溃的事实，并为此生成分析事件。您还可以看到这些只是详细级别的严重性消息。真正的崩溃将伴随着带有错误级别严重性消息的消息，并且通常伴随着 Java 堆栈跟踪。
