Opening Keynote: Android Then & Now
summary
A concise timeline: Android shifts from Dalvik to ART (faster runtime, shorter GC pauses), adds Treble to separate vendor drivers, and builds Jetpack libraries including Jetpack Compose and Kotlin extensions. Platform tightens battery and privacy with app standby buckets, Doze++, scoped storage, Wi‑Fi scan limits and background service/location restrictions. Non‑SDK calls move to whitelist/blacklist and background activity launches are blocked — the platform reports preventing 18 million pop-ups in a week, a measurable drop in bad UX.
