I need a clean, stable Android application that plugs into our existing school ERP database and splits the experience across three roles. Student panel • View fees status in real time, synced with our ERP ledger • Access timetable with day-wise periods pulled from the central schedule Teacher panel • Upload study materials (PDF, PPT, video) to the correct class or section • Send announcements that trigger push notifications and store in an inbox Admin panel • Manage fees collection with dashboard totals, filters by class and date, and one-tap reconciliation • Access profit & loss reports generated from the same fees data and other expense inputs • Manage teacher and student data—add, edit, deactivate, or bulk-import records ERP connectivity will be through our REST API; I can provide the endpoints and documentation. The UI should follow modern Material Design guidelines and run smoothly on Android 8.0 and above. Code must be well-commented and handed over in an Android Studio project so we can maintain it internally. On delivery I will test: 1. Successful login for each role with only the screens authorized to them. 2. Real-time updates of fees paid appearing in both student and admin views. 3. Profit & loss report accuracy against a CSV I will supply. If you have relevant experience integrating Firebase Cloud Messaging, SQLite caching, or similar, let me know—that would be a plus, though not mandatory.
