# Android Release 打包脚本
#
# Usage:
#   bash scripts/build_android.sh apk               # APK（本地测试 / 内部分发）
#   bash scripts/build_android.sh aab               # AAB（Google Play 上架）
#   bash scripts/build_android.sh apk prod          # APK + prod 配置（CI 使用）
#   bash scripts/build_android.sh aab prod          # AAB + prod 配置（CI 使用）
#
# Via melos:
#   melos run build:android:apk
#   melos run build:android:aab
#
# 产物路径：
#   APK → apps/im_app/build/app/outputs/flutter-apk/app-release.apk
#   AAB → apps/im_app/build/app/outputs/bundle/release/app-release.aab
#   符号表 → apps/im_app/build/debug-info/android/（保留用于线上崩溃还原堆栈）
