Android's Kotlin UI toolkit: composable functions describe screens from state and can interoperate with existing Views. Keep data operations outside rendering and test lifecycle behavior.

Reach for it when:
- Native Android interfaces
- Incremental adoption alongside existing Android Views

Worth knowing: Part of Apache-2.0-licensed AndroidX. This entry covers Android Jetpack Compose; Compose Multiplatform has a different platform scope. Device work still follows Android permissions and background restrictions.
