- Navigation Compose: Type-safe navigation framework simplifying screen navigation
- Coil: Efficient image loading library optimizing image display performance
Business Logic Layer¶
- Jetpack ViewModel: Manages UI-related data and handles configuration changes
- Kotlin Coroutines: Simplifies asynchronous programming with structured concurrency
- Flow: Reactive programming framework supporting data stream processing
- StateFlow: Reactive state container simplifying state management
Data Layer¶
- Room Database: Provides type-safe data access, supporting SQLite operations
- Retrofit: Type-safe HTTP client simplifying network requests
- OkHttp: Efficient HTTP client providing interceptors and cache support
- Kotlinx Serialization: High-performance JSON serialization library
- Moshi: Flexible JSON parsing library seamlessly integrated with Retrofit
Image Processing¶
- CameraX API: Simplifies camera operations, providing consistent user experience
- Custom Image Processing Algorithms: Edge detection, perspective correction, image enhancement, etc.
- Bitmap Processing: Image scaling, cropping, filter application, etc.
Secure Communication¶
- RSA/AES Encryption: Hybrid encryption system protecting data transmission security
