React Native 错误 Unable to extract native debug metadata

Question

我正在使用 react-native v0.65.1 并且在生成 apk 时收到很多错误

> Task :app:extractReleaseNativeSymbolTables

它很长，但我缩短了它，因为它是关于 arm64-v8a ABI 的。当我安装生成的 APK 并打开它时，它立即关闭。由于开发没有任何错误，不知道发生了什么。

已经研究了 2 天了，但我仍然找不到任何可以解决这个问题的方法。期待您的帮助。谢谢！

Answer 1

我设法找到了这个问题的原因。我使用 android studio 打开了我的项目（仅打开 android 文件夹）并尝试从那里运行ning 它并且模拟器正在显示

Unable to load script. Make sure you’re either running a Metor service (run ‘react-native start’) or that your bundle ‘index.android.bundle’ is packaged correctly for release.

P/S: 当我做 npx react-native run-android.

时上面的错误没有出现

发现这篇非常有用的文章React Native: Unable to load script: index. android.bundle

我所做的是，在 app/build.gradle 中有这一行 project.ext.react 并添加了 bundleInRelease: true 因为我想生成一个已发布的 APK。只需运行 gradlew assembleRelease 来自 android 文件夹。

我自己也有这个问题，最后发现是因为我没有正确连接“NDK”。

采取的修复步骤：

Android Studio > 工具 > SDK 管理器 > SDK 工具 > Select 并安装“NDK（并排）” 如果本地已经安装了 NDK 版本，则可能没有必要。通常在 ~/Android/Sdk/ndk/<versionNumber>/
在项目中，在文件 /android/build.gradle 中，将 ndkVersion 设置为正确的版本：
```
buildscript {
    ext {
        // ...
        ndkVersion = "24.0.8215888"
     }
}
```
