/create-activity - Create Android Activity/Screen

Generate a Jetpack Compose screen with proper architecture.

Steps

1. Ask the user for the screen name, purpose, and navigation requirements 2. Create the Composable function with the screen content 3. Add a ViewModel class for the screen's state management 4. Define the UI state as an immutable data class with all screen properties 5. Implement the screen layout using Compose components: Column, Row, LazyList 6. Add navigation parameters using Navigation Compose type-safe arguments 7. Include loading, error, and empty state handling with proper UI 8. Add Material 3 theming: colors, typography, shapes from the app theme 9. Implement pull-to-refresh, pagination, or infinite scroll if applicable 10. Add content descriptions for accessibility (TalkBack support) 11. Create a Compose Preview with @Preview annotation and sample data 12. Register the screen in the navigation graph

Rules

• Follow the UDF (Unidirectional Data Flow) pattern with ViewModel
• Use StateFlow in ViewModel, collected as State in Composable
• Keep Composable functions stateless; hoist state to the caller
• Use remember and derivedStateOf for expensive computations
• Follow Material 3 guidelines for spacing, elevation, and component usage
• Support both portrait and landscape orientations
• Add string resources for all user-visible text (no hardcoded strings)
