## 📊 Performance Analysis
|
|
|
|
### Memory Usage (Estimated)
|
|
- App base: ~50 MB
|
|
- Database: ~1-5 MB (depending on records)
|
|
- Photo Bitmap: ~2-4 MB per photo
|
|
- Photo Base64: ~4-8 MB per photo (when encoded)
|
|
|
|
### Network Traffic
|
|
- Single attendance request: ~5-8 MB (including photo Base64)
|
|
- Webhook response: ~1 KB
|
|
|
|
### Database Performance
|
|
- Query attendance history: O(n) where n = number of records
|
|
- Add record: O(1)
|
|
- Recommended: Index on `npm` column for faster queries

## 📋 Known Issues & Limitations
|
|
|
|
### Current Limitations
|
|
1. **Photo Storage**: Foto hanya di memory, tidak persistent
|
|
2. **Database Sync**: No real-time sync ke server
|
|
3. **Offline Support**: Limited offline functionality
|
|
4. **Coordinate Precision**: Default location hardcoded
|
|
5. **Error Recovery**: Manual retry diperlukan jika gagal
|
|
|
|
### Potential Issues
|
|
- Photo compression loss di quality
|
|
- Large database untuk banyak users
|
|
- Memory leak jika bitmap tidak release
|
|
- Network timeout tidak retry otomatis
|
|
|
|
### Solutions Provided
|
|
- `obfuscateCoordinates()` untuk privacy control
|
|
- Local database fallback jika offline
|
|
- Try-catch untuk error handling
|
|
- Thread untuk non-blocking operations
|
|
