我有一个包含很多 Activity 的应用程序，其中一些 Activity 已连接到Firebase数据库。最近，当我同时进行具有Firebase调用的 Activity 和之前的 Activity 时，我已经开始体验崩溃。应用程序崩溃后，它将重新启动，然后按预期方式工作。因此，只有在我通过USB安装它之后，它才能这样做。当崩溃发生时，Logcat会显示以下内容:
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，我不知道该怎么办...很明显，它来自Firebase，但确切地来自哪里？

}在阅读了这个错误here之后，我发现有人暗示这可能是字符长度的问题，但是我不知道这是否是我的问题。我的数据库中没有超过40个字符。
Firebase上的数据库配置如下图所示:
错误是模糊的，我真的不知道从哪里开始。谁能帮我？谢谢!
最佳答案
您显示的日志不是因为此时您的应用崩溃了。那就是Firebase的Google Analytics(分析)记录您的应用先前崩溃的事实，并为此生成了分析事件。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，并且通常还会附带Java堆栈跟踪。
