A2UI for Android: Safely Rendering AI-Generated UI with Jetpac…
summary
A2UI defines a declarative JSON protocol that renders agent‑generated interfaces with Jetpack Compose using a catalog allowlist and Material 3 widgets, avoiding code execution and WebView risks. It maps createSurface, updateComponents, updateDataModel messages to Compose state for progressive rendering, supports on‑device functions and bidirectional RPC so local taps and validation run with zero network latency, and streams component chunks (example: a layered delivery survey with star ratings) while the renderer rejects invalid payloads. Version 1.0 is a release candidate.
