# Camera Technical Implementation — Details and Best Practices
|
|
|
|
> **Agent role**: Reference this file for
|
|
detailed technical implementation when working with camera features.
|
|
|
|
## Platform-Specific Considerations
|
|
|
|
### iOS
|
|
|
|
- Requires `NSCameraUsageDescription` in Info.plist
|
|
|
|
- Supports both front and back cameras
|
|
|
|
- Implements proper permission handling
|
|
|
|
### Android
|
|
|
|
- Requires camera permissions in manifest
|
|
|
|
- Supports both front and back cameras
|
|
|
|
- Handles permission requests through Capacitor
|
|
|
|
### Web
|
|
|
|
- Requires HTTPS for camera access
|
|
|
|
- Implements fallback mechanisms
|
|
|
|
- Handles browser compatibility issues
|
|
|
|
## Error Handling
|
|
|
|
### Common Error Scenarios
|
|
|
|
1. No camera found
|
|
|
|
2. Permission denied
|
|
|
|
3. Camera in use by another application
|
|
|
|
4. HTTPS required
|
|
|
|
5. Browser compatibility issues
|
|
|
|
### Error Response
|
|
|
|
- User-friendly error messages
|
|
|
|
- Troubleshooting tips
|
|
|
|
- Clear instructions for resolution
|
|
|
|
- Platform-specific guidance
|
|
|
|
## Security Considerations
|
|
|
|
### Permission Management
|
|
|
|
- Explicit permission requests
|
|
|
|
- Permission state tracking
|
|
|
|
- Graceful handling of denied permissions
|
|
|
|
### Data Handling
|
|
|
|
- Secure image processing
|
|
|
|
- Proper cleanup of camera resources
|
|
|
|
- No persistent storage of camera data
|
|
|
|
## Best Practices
|
|
|
|
### Camera Access
|
|
|
|
1. Always check for camera availability
|
|
|
|
2. Request permissions explicitly
|
|
|
|
3. Handle all error conditions
|
|
|
|
4. Provide clear user feedback
|
|
|
|
5. Implement proper cleanup
|
|
|
|
### Performance
|
|
|
|
1. Optimize camera resolution
|
|
|
|
2. Implement proper resource cleanup
|
|
|
|
3. Handle camera switching efficiently
|
|
|
|
4. Manage memory usage
|
|
|
|
### User Experience
|
|
|
|
1. Clear status indicators
|
|
|
|
2. Intuitive camera controls
|
|
|
|
3. Helpful error messages
|
|
|
|
4. Smooth camera switching
|
|
|
|
5. Responsive UI feedback
|
|
|
|
