Google held its first Android Dev Summit events in four years last week, with events in Mountain View and London, and videos and Gemini Notebooks are now available. Florina Muntenescu wrote that over 900 attendees joined the event spaces for a keynote, demo sessions, dozens of workshops, a hackathon, and community discussions focused on ideas and feedback on the Android platform. Google posted over 50 sessions from the events, plus the keynote and more, on YouTube and the Android Developer website. Key videos and session track playlists include the Android Dev Summit 2026 keynote, Android XR, Android apps foundation, Android tools & performance, Android intelligent apps, and all sessions. Gemini Notebooks with enhanced transcripts are available for each of the session tracks; Muntenescu explained that the transcripts are enhanced with content from the session slides so users and their agents can get the full context of the talk, and users can download them to drop the transcript into an agent of choice and integrate the takeaways in their app.
