今天早上在病房，我面临着 React Native Android 构建的问题。代码中的新更改未反射(reflect)在设备上。没有构建失败。我尝试了以下方法
- 删除并重新安装节点模块
- react-native 链接
- ./gradlew 干净 React-Native Bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/应用程序/src/main/res
- 看守关闭服务器
- rm -rf/usr/local/var/run/watchman &&brew 卸载 watchman &&brew 安装 watchman
- npm start - --reset-cache

最佳答案
不要使用react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res用于在 Android 中运行 React Native。此命令将 JS 服务器 bundle 在包(APK)中。因此，将不会与系统上运行的 Metro 服务器进行通信。
使用react-native run-android用于调试应用程序的命令。在此 js 服务器中，不会随包一起提供。因此，当您刷新应用程序时，更改将会反射(reflect)出来
