Jetpack Compose is Android's recommended modern toolkit for building native UI with less code, powerful tools, and intuitive Kotlin APIs. It simplifies and accelerates UI development, including adaptation to any form factor—from smartphones, foldables, and tablets to TVs and wearables.

Compose offers pre-built UI components that work with graphics, animations, and other visual elements.

For existing views-based UIs, you can choose to migrate to Compose or continue to use views-based workflows.
