A hands-on walkthrough of Android's experimental AppFunctions API. I build a small but complete notes app, expose four functions to on-device agents with @AppFunction, and trace exactly what the KSP compiler generates and how the system discovers and invokes them.

Part 2 of the foldables series. We build an adaptive media player in Jetpack Compose that reacts to tabletop and book postures with Jetpack WindowManager, picks list-detail layouts with window size classes, and verify all of it on the Pixel Fold emulator.
