You can integrate ViewModel in Jetpack Compose by hoisting state upward into the ViewModel class, exposing mutable state, and collecting it inside composables to ensure separation of concerns and testability.

Handling side effects in declarative Android UIs requires using Compose side-effect APIs like LaunchedEffect, applying state hoisting patterns, and ensuring composables remain side-effect free during recomposition.

Yes, this declarative approach supports navigation and theming natively, allowing you to build cohesive Android apps by integrating navigation components and applying consistent Material themes within your composables.

Use derivedStateOf in Jetpack Compose to prevent unnecessary recomputations when a state depends on other states, whereas use rememberSaveable specifically to preserve UI state across process death and configuration changes.

Yes, you can build native Android interfaces entirely without traditional XML layouts by using Jetpack Compose to write declarative @Composable functions that directly define your UI structure and behavior.
