How do you manage UI state on Android (ViewModel, LiveData, Flow)?

Answer

Move state out of Activities/Fragments into ViewModels. Use: - LiveData for lifecycle-aware updates - StateFlow/Flow for reactive streams Model UI state as a sealed class (Loading/Success/Error) to simplify rendering and avoid inconsistent UI. Keep side effects (navigation, toasts) separate from state updates.
