This is an Android application named 'Parcel - Pickup Code' that automatically parses incoming SMS text messages to extract parcel pickup codes and delivery addresses. The app displays the extracted information on home screen widgets (available in multiple sizes) and provides a rich UI built with Jetpack Compose. Core features include: automatic SMS parsing with configurable custom regex rules, support for monitoring third‑party app notifications (WeChat, Pinduoduo, TikTok, Xiaohongshu) to capture pickup codes, address grouping with labels, senior mode with enlarged text, dark theme, and persistent data storage via SharedPreferences. The architecture follows standard Android patterns: a main activity orchestrates permissions and data refresh, a ViewModel manages state, a dedicated SMS parser processes messages, and background services (NotificationListenerService, periodic health checks) keep widgets updated. The app is deliberately offline and does not collect personal data.
