Why is MVVM better than other Android design patterns? Explain ViewModel.
Asked in the Sr. Android Engineer round stage. Discuss MVVM's advantages compared with patterns such as MVC and MVP, including separation of concerns, testability, lifecycle handling, and maintainability. Explain what an Android ViewModel is, what responsibilities it should have, how it survives configuration changes, and how it communicates with UI components. Mention appropriate use of repositories, observable state such as StateFlow or LiveData, and why a ViewModel should not hold references to Activities, Fragments, or Views.
