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.
