问题描述

我把 Android 文件夹中的文件弄乱了，想在 Android 文件夹中重建 Android 项目.我该怎么做呢?

I have messed the files up in the Android folder and would like to rebuild the Android project inside of the Android folder. How do I do this?

删除 Android 文件夹然后运行 ​​react-native run-android 是否安全，是否会再次出现?

Is it safe to delete the Android folder and then run react-native run-android, will that make it again?

我编写的所有代码都是在 index.android.js 中编写的.

Everything I've coded was wrote in index.android.js.

推荐答案

我遇到了类似的问题，./gradlew clean没有用，但我从 How我可以在 React Native 项目中重新生成 ios 文件夹吗?

I had similar problem, and ./gradlew clean didn't work, but i found hacky solution from How can I regenerate ios folder in React Native project?

删除android文件夹(也可能是ios)，然后是hacky部分->:

Delete android folder (probably ios too), and then hacky part ->:

react-native upgrade 

(它会重新生成文件夹，但不应该用于升级 RN..)

(it regenerates folders, but it shouldn't be used to upgrade RN..)

然后

react-native link
react-native run-android

它对我有用:)

一个观察 -> react-native 有时会发疯并且无法运行某些命令.启动新终端有帮助.奇怪:)

EDIT : one observation -> react-native sometimes goes crazy and cannot run some commands. Launching a new terminal helps. Bizarre :)
