Android Developers: Let agents generate UI in your Android apps with A2UI

A2UI is transitioning from web-centric components to native Android. The new Jetpack Compose renderer for A2UI v0.9 enables developers to render dynamic, LLM-generated UI natively. Instead of webviews, it leverages a Coroutine-driven actor framework, sealed-class lifecycles, and native Material 3 integration.



This session walks through the new architecture, explaining how server-driven component trees translate into reactive Compose nodes, and how built-in layout transitions handle structural updates smoothly without blocking the UI.
