Android Architecture Components (AAC) are a set of libraries designed to facilitate robust, maintainable, and testable applications. Key components include:
1. LiveData: An observable data holder class that respects the lifecycle of app components, automatically managing subscriptions and preventing memory leaks.
2. ViewModel: A class responsible for preparing and managing data for UI components, surviving configuration changes, and decoupling data from activities/fragments.
3. Room: A SQLite object-mapping library providing compile-time checks and boilerplate code reduction, simplifying database operations.
4. Data Binding: A support library enabling binding UI components directly to data sources, reducing boilerplate code and improving readability.
5. Paging: A library handling large datasets efficiently by loading small chunks as needed, optimizing resource usage and user experience.
6. WorkManager: A library managing deferrable background tasks, ensuring execution under various constraints while respecting system optimizations.
These components work together to promote modular architecture, separation of concerns, and efficient resource management in Android applications.
