Modern Android architecture has converged around a hybrid pattern called 'MVI-flavored MVVM' that combines MVVM's ViewModel container with MVI's unidirectional data flow principles. Google promotes UDF (Unidirectional Data Flow) rather than prescribing strict pattern names, allowing flexibility. The practical implementation uses three core elements: a single UiState data class (StateFlow), side effects via Channel, and a single Intent entry point on the ViewModel. This approach simplifies debugging, enables reactive UI with Jetpack Compose, and represents the de facto standard for Android development in 2026.
