响应不反映在设备上的本机代码更改

Question

今天早上在wards上，我面临一个react原生android构建的问题。代码中的新更改不反映在设备上。没有生成失败。我试了以下几种

• 已删除并重新安装节点模块
• 反应-本机链接
• ./gradlew clean
• 反应-本机包--平台android--开发人员false--条目-文件index.js--bundle-输出android/app/src/main/assets/index.android.bundle-assets-dest android/app/src/main/res
• Watchman关闭-服务器
• rm-rf/usr/local/var/run/watchman&&brew卸载watchman&&brew安装watchman
• NPM启动----重置-缓存

我的Package.json

Answer 1

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在android中运行react native。这个命令将JS服务器捆绑在包（APK）中。因此将无法与系统上运行的metro服务器进行通信。

使用react-native run-android命令调试应用程序。在这种情况下，js服务器不会随包一起出货。所以当您刷新应用程序时，这些更改将会反映出来
