        os: [macos-latest, ubuntu-latest, windows-latest]
    runs-on: ${{ matrix.os }}

    steps:
      - uses: actions/checkout@v4

      - name: Configure Android env (macOS/Linux)
        if: runner.os != 'Windows'
        shell: bash
        run: |
          echo "ANDROID_HOME=$ANDROID_SDK_ROOT" >> "$GITHUB_ENV"
          echo "ANDROID_SDK_HOME=$RUNNER_TEMP/android-home" >> "$GITHUB_ENV"
          echo "ANDROID_NDK_HOME=$ANDROID_SDK_ROOT/ndk/${NDK_VERSION}" >> "$GITHUB_ENV"
          echo "$ANDROID_SDK_ROOT/cmdline-tools/latest/bin" >> "$GITHUB_PATH"
      - name: Configure Android env (Windows)
        if: runner.os == 'Windows'
        shell: pwsh
        run: |
          Add-Content $env:GITHUB_ENV "ANDROID_HOME=$env:ANDROID_SDK_ROOT"
          Add-Content $env:GITHUB_ENV "ANDROID_SDK_HOME=$env:RUNNER_TEMP\android-home"
          Add-Content $env:GITHUB_ENV "ANDROID_NDK_HOME=$env:ANDROID_SDK_ROOT\ndk\${{ env.NDK_VERSION }}"
          Add-Content $env:GITHUB_PATH "$env:ANDROID_SDK_ROOT\cmdline-tools\latest\bin"
      - name: Install NDK via preinstalled sdkmanager (macOS/Linux)
        if: runner.os != 'Windows'
        shell: bash
        run: |
          sdkmanager "ndk;${NDK_VERSION}"
          test -d "$ANDROID_SDK_ROOT/ndk/${NDK_VERSION}"
      - name: Install NDK via preinstalled sdkmanager (Windows)
        if: runner.os == 'Windows'
        shell: pwsh
        run: |
          sdkmanager "ndk;$env:NDK_VERSION"
          if (!(Test-Path "$env:ANDROID_SDK_ROOT\ndk\$env:NDK_VERSION")) {
            throw "NDK $env:NDK_VERSION not found"
          }
