推荐答案

1-创建一个新文件夹=> android/app/src/main/assets
2-运行此命令=>

1- Create a new folder => android/app/src/main/assets
2- Run this command =>

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

此命令将创建2个文件: index.android.bundle & index.android.bundle.meta

This command will create 2 files : index.android.bundle & index.android.bundle.meta

3-运行命令=> react-native run-android

3- run command => react-native run-android
