# App Expo：CI 内生成 Android 签名 APK（expo prebuild + Gradle assembleRelease）
# 使用 app-expo/plugins/withAndroidReleaseSigning：在 android/app 放置 keystore.properties + jks 后打 release 包。
#
# 产物说明：
#   - 以下为「真机向」release APK；Google Play 上架更推荐 AAB（按设备 ABI 下发）。
#   - 构建步骤会将 reactNativeArchitectures 设为仅 arm64-v8a（更小；不含 x86/x86_64，多数模拟器无法安装）。
#   - 若需兼容旧 32 位 ARM 设备，可将该属性改为 armeabi-v7a,arm64-v8a（体积会增大）。
#   - 若需用 x86 模拟器验证此 APK，需改回含 x86 的 ABI 或另建 job。
#
# 环境映射（与后端 api 一致：main → 预发 staging，tag → 生产 production）：
#   push main     → stage   → node scripts/use-env.js staging → env/staging → .env
#   push v*.*.*   → prod    → node scripts/use-env.js production → env/production → .env
#
# 手动触发 workflow_dispatch：
#   - dev：内部测试包，使用 env/development
#   - stage：仅用于 main / master 补跑 Staging release，使用 env/staging
#   - prod：用于 vMAJOR.MINOR.PATCH tag，或在 main / master 上填写 version 后发正式 Release
#
# Repository secrets（与 android-release.yml 共用同一套即可）：
#   ANDROID_KEYSTORE_BASE64 / ANDROID_STORE_PASSWORD / ANDROID_KEY_ALIAS / ANDROID_KEY_PASSWORD
#
# 版本注入（app.config.ts 读取，与 Gradle -PversionName/-PversionCode 对齐）：
#   APP_VERSION       — tag / 手动 version / staging 时 package.json
#   APP_BUILD_NUMBER  — GITHUB_RUN_NUMBER（Android versionCode / iOS buildNumber）
