Technology Selection Rationale and Advantages
This section explains the reasoning behind the technology choices made for DocuSnap-Frontend and the advantages these technologies bring to the application.
Jetpack Compose
Rationale: Traditional XML layout systems are complex and difficult to maintain, especially for complex UI interactions.
Advantages:
- Declarative UI simplifies building complex interfaces
- Built-in animation and state management
- Seamless integration with Kotlin, improving development efficiency
- Reduced boilerplate code, improving readability
- Real-time preview, accelerating development iteration
MVVM Architecture
Rationale: Need for clear separation of UI, business logic, and data access.
Advantages:
- Separation of concerns, improving code maintainability
- Support for unit testing, improving code quality
- Clear UI state management, reducing state-related bugs
- Well-suited for data-driven application scenarios
- Compatible with the Jetpack component ecosystem
Kotlin Coroutines
Rationale: Asynchronous operations (such as network requests, database access) need a concise handling approach.
Advantages:
- Simplifies asynchronous programming, avoiding callback hell
- Structured concurrency, making lifecycle management easier
- Combined with Flow, supports reactive programming
- Reduces the complexity of thread management
- Improves code readability and maintainability
Room Database
Rationale: Need for reliable local data storage and offline functionality support.
Advantages:
- Type-safe data access
- Compile-time SQL validation
- Seamless integration with Kotlin Coroutines and Flow
- Simplified database migration
- Support for complex queries and relationship mapping
CameraX
Rationale: Need for stable, consistent camera experience while simplifying camera operations.
Advantages:
- Simplifies camera lifecycle management
- Cross-device consistency
- Built-in common use cases (preview, photo capture, video recording)
- Integration with Jetpack lifecycle components
- Support for image analysis and extension features
These technology choices reflect a careful consideration of the application’s requirements, modern Android development best practices, and the need for a maintainable, efficient, and user-friendly application.
