AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a comprehensive guide to building native Android interfaces using Jetpack Compose and Material Design 3. It covers essential UI components, navigation patterns, and best practices for creating responsive, accessible, and performant Android applications. The content includes practical code examples for common UI elements like lists, forms, and navigation structures, alongside guidance on state management and theming.

What it does

Provides patterns for implementing Material Design 3 components and theming.
Demonstrates building UI layouts using Jetpack Compose.
Explains type-safe navigation implementation with Navigation Compose.
Offers best practices for state management and recomposition performance.
Includes examples for common UI patterns like lazy lists, swipe-to-dismiss, and forms.
Covers accessibility considerations for Android interface design.

When to use it

When designing or building native Android application interfaces.
When implementing modern UI components using Jetpack Compose.
When migrating or adopting Material Design 3 guidelines in an Android project.
When setting up navigation flows in a Compose-based Android app.
When optimizing Android UI for different screen sizes and configurations.

Advantages

Promotes consistent UI design using official Material 3 standards.
Provides ready-to-use code snippets for common Android UI components.
Encourages best practices for performance and state management in Compose.
Facilitates the creation of adaptive and accessible Android layouts.

Usage examples

“How do I implement a list with swipe-to-dismiss functionality in Jetpack Compose?”: The skill provides a SwipeableItem component example using SwipeToDismissBox and rememberSwipeToDismissBoxState to handle deletion logic.
“Show me how to set up type-safe navigation between screens in my Android app.”: The skill demonstrates using @Serializable objects and data classes with NavHost and composable functions to manage navigation routes.

Quick Start Component

@Composable
fun ItemListCard(
    item: Item,
    onItemClick: () -> Unit,
    modifier: Modifier = Modifier
) {
    Card(
        onClick = onItemClick,
        modifier = modifier.fillMaxWidth(),
        shape = RoundedCornerShape(12.dp)
    ) {
        Row(
            modifier = Modifier
                .padding(16.dp)
                .fillMaxWidth(),
            verticalAlignment = Alignment.CenterVertically
        ) {
            Box(
                modifier = Modifier
                    .size(48.dp)
                    .clip(CircleShape)
                    .background(MaterialTheme.colorScheme.primaryContainer),
                contentAlignment = Alignment.Center
            ) {
                Icon(
                    imageVector = Icons.Default.Star,
                    contentDescription = null,
                    tint = MaterialTheme.colorScheme.onPrimaryContainer
                )
            }

            Spacer(modifier = Modifier.width(16.dp))

            Column(modifier = Modifier.weight(1f)) {
                Text(
                    text = item.title,
                    style = MaterialTheme.typography.titleMedium
                )
                Text(
                    text = item.subtitle,
                    style = MaterialTheme.typography.bodyMedium,
                    color = MaterialTheme.colorScheme.onSurfaceVariant
                )
            }

            Icon(
                imageVector = Icons.Default.ChevronRight,
                contentDescription = null,
                tint = MaterialTheme.colorScheme.onSurfaceVariant
            )
        }
    }
}

Best Practices

Use Material Theme: Access colors via MaterialTheme.colorScheme for automatic dark mode support
Support Dynamic Color: Enable dynamic color on Android 12+ for personalization
Adaptive Layouts: Use WindowSizeClass for responsive designs
Content Descriptions: Add contentDescription to all interactive elements
Touch Targets: Minimum 48dp touch targets for accessibility
State Hoisting: Hoist state to make components reusable and testable
Remember Properly: Use remember and rememberSaveable appropriately
Preview Annotations: Add @Preview with different configurations

Common Issues

Recomposition Issues: Avoid passing unstable lambdas; use remember
State Loss: Use rememberSaveable for configuration changes
Performance: Use LazyColumn instead of Column for long lists
Theme Leaks: Ensure MaterialTheme wraps all composables
Navigation Crashes: Handle back press and deep links properly
Memory Leaks: Cancel coroutines in DisposableEffect

        verticalArrangement = Arrangement.spacedBy(8.dp)
    ) {
        items(
            items = items,
            key = { it.id }
        ) { item ->
            ItemRow(
                item = item,

                true
            } else {
                false

                    .padding(horizontal = 20.dp),
                contentAlignment = Alignment.CenterEnd
            ) {

            }
        }
    ) {
        ItemRow(item = item)
    }

@Composable
fun GroupedList(
    groups: Map<String, List<Item>>
) {
    LazyColumn {
        groups.forEach { (header, items) ->
            stickyHeader {
                Surface(
