MVVM in Android
MVVM (Model-View-ViewModel) in Android is a powerful architectural pattern that enhances app development by promoting a clear separation of concerns. It simplifies the management of UI-related data and workflows, making applications more maintainable, testable, and scalable. By decoupling the user interface from business logic and data handling through the ViewModel, developers can easily implement features like data binding and live data updates, resulting in a more responsive and robust user experience. Overall, adopting MVVM streamlines development and improves the quality of Android applications.
