Introduction and deep dive into dual screen foldables app development.
summary
Surface Duo launches in H2 2020 and runs Android 10; code samples and a beta open‑source SDK live on GitHub and an emulator. The session shows concrete APIs: Drag & Drop via ClipData, DragShadowBuilder and global URI flags; starting an activity on the adjacent screen with an intent and task flags; spanning detection using Jetpack Window Manager and reading hinge bounds from WindowLayoutInfo; layout helpers in the Surface Duo layout library; UI tests use UIAutomator swipe coordinates to span and unspan.
