summary
Announcement gives concrete foldable specs: 7.3‑inch main display and a 4.5‑inch cover with 420/320 dp metrics, support for up to three simultaneous multi‑active windows, and unfolding treated as a configuration change (use ViewModel or handle config yourself); multi‑resume is an opt‑in flag now with OEM support and a Samsung emulator hitting Q4 for testing. Measured OLED savings are large—about 63% power drop vs light UI and app wins like YouTube ~43% (playing) / ~60% (paused) and Gboard ~20% from dark themes. Background work tooling updates include WorkManager alpha11 with Worker/ListenableWorker, chaining, Operations API and testing advice; for rich coordinated motion the new MotionLayout workflow and keyframe features handle touch‑driven, multi‑state animations.
