如何在GitHub Actions中安装AIDL解决Buildozer构建报错

问题原因 #

你使用的ArtemSBulgakov/buildozer-action是在独立Docker容器中执行打包操作的，之前在Get Date步骤中通过apt安装的依赖仅作用于GitHub Actions的主机环境，并不会进入Buildozer运行的容器内部，因此容器内仍然缺少aidl工具。

解决方案 #

方法一：利用buildozer-action的extra_packages参数（推荐） #

该Action提供了extra_packages参数，可直接在容器内部安装所需的系统依赖，无需手动操作容器环境。修改build.yml中的Build with Buildozer步骤：

- name: Build with Buildozer
  uses: ArtemSBulgakov/buildozer-action@v1
  id: buildozer
  with:
    command: buildozer -v android debug
    buildozer_version: master
    extra_packages: build-essential libstdc++6 aidl

方法二：手动在容器内执行安装命令 #

如果需要更灵活的环境配置，可以在Buildozer打包步骤前，进入Action使用的容器执行依赖安装。不过这种方式不如方法一简洁，示例如下：

- name: Install dependencies in Buildozer container
  run: |
    docker run --rm -v $PWD:/app artemsbulgakov/buildozer-action:master \
      apt-get update && apt-get install -y build-essential libstdc++6 aidl

验证修改后的完整build.yml #

修改后的配置文件示例：

name: CI
on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]
  schedule:
    - cron: '0 0 1,15 * *'

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2

      - name: Get Date
        id: get-date
        run: |
          echo "::set-output name=date::$(/bin/date -u "+%Y%m%d")"
        shell: bash

      - name: Cache Buildozer global directory
        uses: actions/cache@v2
        with:
          path: .buildozer_global
          key: buildozer-global-${{ hashFiles('buildozer.spec') }}

      - uses: actions/cache@v2
        with:
          path: .buildozer
          key: ${{ runner.os }}-${{ steps.get-date.outputs.date }}-${{ hashFiles('buildozer.spec') }}

      - name: Build with Buildozer
        uses: ArtemSBulgakov/buildozer-action@v1
        id: buildozer
        with:
          command: buildozer -v android debug
          buildozer_version: master
          extra_packages: build-essential libstdc++6 aidl

      - name: Upload artifacts
        uses: actions/upload-artifact@v2
        with:
          name: package
          path: ${{ steps.buildozer.outputs.filename }}
