无法使用Crashlytics为ReactNative找到有意义的日志 [英] Unable to find meaningful logs for ReactNative using Crashlytics

问题描述

我已将Crashlytic集成到reactNative应用程序中，并试图检查从js文件生成的崩溃日志。它能够捕获它们，但不提供有关文件名的信息。日志从index.android.bundle文件给出位置，很难提供有关崩溃位置的任何信息。
我已经尝试过

I have integrated Crashlytic in reactNative application and tried to check crash logs generated from js files. Its able to capture them but not providing information about the file name. Logs are giving location from index.android.bundle file which are hard to provide any information about crash location. I have already tried

• react-native-fabric-crashlytics和react-native-fabric npm模块


• 如

• react-native-fabric-crashlytics and react-native-fabric npm modules
• Setting default logger for react native as mentioned in

，但没有用。仍然出现日志，如下所述

but there is no use. Still logs are coming as mentioned below

推荐答案

我认为原因是您使用-dev false 生成了包。尝试使用-dev true 构建软件包。

I think the reason is that you generate your bundle with --dev false. Try to build your bundle with --dev true. It will generate unminified (e.g. normal) Javascript.

react-native bundle --platform android --dev true --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/
