推荐开源项目：自动构建React Native安卓APK的GitHub Action

以下是一个简化的GitHub Action工作流代码实例，用于自动构建React Native项目的Android APK：

name: Build React Native Android APK
 
on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]
 
jobs:
  build:
    runs-on: ubuntu-latest
 
    steps:
    - name: Checkout code
      uses: actions/checkout@v2
 
    - name: Set up Java
      uses: actions/setup-java@v1
      with:
        java-version: 1.8
 
    - name: Set up Android SDK
      uses: android-actions/sdk-manager@v1
      with:
        packages: build-tools;28.0.3,platforms;android-28
 
    - name: Install dependencies
      run: yarn install
 
    - name: Bundle React Native
      run: yarn 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
 
    - name: Build APK
      run: cd android && ./gradlew assembleRelease
 
    - name: Upload APK
      uses: actions/upload-artifact@v1
      if: success()
      with:
        name: apk
        path: android/app/build/outputs/apk/release/app-release.apk

这个工作流程在收到push或pull request至main分支时会运行。它会检出代码，设置Java环境，下载并安装Android SDK，安装项目依赖，打包React Native的JavaScript代码，构建APK，并在构建成功的情况下上传APK文件作为工作流程产物。这样可以保证React Native项目的Android APK可以自动构建，提高了开发效率。
