Introducing Cahier: A new Android GitHub sample for large screen productivity and creativity

Google introduces Cahier, an open-source Android sample app demonstrating best practices for building productivity and creativity apps on large screens. The app showcases the Ink API (now in beta) for low-latency stylus input, adaptive UI using Material 3 components, multi-window and multi-instance support, drag-and-drop functionality, and the notes role feature for system-wide integration. Built with Jetpack Compose and Room, Cahier serves as a comprehensive reference for developers creating note-taking, drawing, and document markup applications optimized for tablets and foldables.
