#
# Usage:
#   ./scripts/build-android.sh [options]
#
# Options:
#   --dev, --development    Build for development environment
#   --test                  Build for testing environment  
#   --prod, --production    Build for production environment
#   --debug                 Build debug APK
#   --release               Build release APK
#   --studio                Open Android Studio after build
#   --apk                   Build APK file
#   --aab                   Build AAB (Android App Bundle)
#   --clean                 Clean build artifacts only
#   --sync                  Sync Capacitor only
#   --assets                Generate assets only
#   --deploy                Deploy APK to connected device
#   -h, --help             Show this help message
#   -v, --verbose          Enable verbose logging
#
# Examples:
#   ./scripts/build-android.sh --dev --studio    # Development build + open studio
#   ./scripts/build-android.sh --prod --apk      # Production APK build
#   ./scripts/build-android.sh --test --aab      # Testing AAB build
#   ./scripts/build-android.sh --clean           # Clean only
#   ./scripts/build-android.sh --sync            # Sync only
#
# Exit Codes:
# 1 - Android cleanup failed
# 2 - Web build failed
# 3 - Capacitor build failed
# 4 - Gradle clean failed
