您将需要 Node、React Native 命令行界面、JDK 和 Android Studio。

我以为你有，开发操作系统:Linux，目标操作系统:Android

节点 https://nodejs.org/en/download/package-manager/

React Native CLI

npm install -g react-native-cli

Java 开发工具包 http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Android开发环境 https://developer.android.com/studio/index.html

守望者(可选) https://facebook.github.io/watchman/docs/install.html#buildinstall

创建新应用程序

$ react-native init AwesomeProject

$ cd AwesomeProject

$ react-native run-android

注意:如果您收到如下错误:“无法在真实设备上从 Assets 'index.android.bundle'加载脚本”

那么，(如果没有创建的话)将目录创建为 android/app/src/main/assets

低于 < 0.46 的旧 React Native 版本

$ 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

或

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

那么，

$ react-native run-android
