firebase - react native 堆栈跟踪

Question

我有 React Native App与 Firebase Crashlytics 相关联。
问题是 firebase 发送不可读的堆栈跟踪，如下所示。有任何方法可以读取这种错误。

我只想知道什么时候抛出错误。

这是我的堆栈跟踪

Answer 1

这叫混淆，你的意思符号 替换为无意义的，以减少生产中的文件大小。通常，当您构建应用程序时，它会生成反混淆文件(通常采用 .dSYM 文件的形式)，可用于 象征你的应用程序。

获取 .dSYM 因您使用的平台而异，但 firebase has a handy guide that should be able to further help in this specific case.

出于文档目的，我将对本答案中提供的步骤进行硬编码。

IOS

Open your project in Xcode, and select the project file in the Xcode Navigator.

Select your main build target from the Select a project or target dropdown.

Open the target's Build Settings tab.

Click All near the top of the tab.

Search for "debug information format".

Set Debug Information Format to DWARF with dSYM File.

To preserve the info Crashlytics needs for readable crash reports, add the following lines to your Proguard or Dexguard config file:

-keepattributes *Annotation*
-keepattributes SourceFile,LineNumberTable
-keep public class * extends java.lang.Exception
