# 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
#   push v*.*.*   → prod    → node scripts/use-env.js production → .env.production
#
# 手动触发 workflow_dispatch：可选 dev / stage / prod（dev 用 .env.development，便于打内部测试包）
#
# 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
