What problem does it solve? Android apps built for phones often break or waste space on tablets, foldables, desktops, TVs, and other form factors. This Skill provides a structured workflow to make an existing Compose UI adaptive across window sizes, input devices, and postures. ## Core Features & Use Cases - Adaptive navigation: Migrates bottom navigation bars to NavigationSuiteScaffold with nav rails on large screens and scroll-aware visibility control. - Multi-pane layouts: Implements list-detail and supporting-pane layouts using Navigation 3 SceneStrategy APIs (ListDetailSceneStrategy, SupportingPaneSceneStrategy). - Adaptive lists and layouts: Converts LazyColumn to adaptive LazyVerticalGrid, migrates non-lazy Column lists to the experimental Grid API, and uses FlexBox and mediaQuery for device-capability-driven layouts. - Use Case: You have a Compose app that shows a single-column list on all devices. Use this Skill to convert it into a two-pane list-detail layout on tablets, switch the bottom bar to a nav rail, and make grids adapt column counts to window width. ## Quick Start Make my Compose app's UI adaptive across phones, tablets, and foldables following the adaptive workflow steps.
