Large screens and foldables
summary
Microsoft shows concrete steps to adapt existing apps: Google reports ~250 million large‑screen users and Microsoft notes 80 Play Store apps already optimized. Samples (two‑page e‑reader, list‑detail nature catalog, full guitar demo on Play Store) use real libraries like Jetpack Window Manager, Microsoft Compose helpers (TwoPaneLayout, window state) and patterns (companion pane, list/detail). Testing uses emulators (Android Studio fold 0–180°, Surface Duo emulator 0–360°, WSA resizable) plus UI Automator spanning and the open‑source Microsoft test kit for fold injection and assertions.
