Earlier this year I built a web app that helps me fix a bike puncture with Gemini, even with no phone signal. It was a Next.js app on Cloud Run, using Firebase AI Logic with Gemini Nano in Chrome as the offline fallback. A web app is the wrong tool at the side of the road, so I'm rebuilding it as a native Android app using Antigravity running inside Android Studio through Bring Your Own Agent (BYOA), with the Android and Firebase agent skills. On-device inference moves from Chrome to Gemini Nano on the phone through the Firebase AI Logic hybrid API, with cloud Gemini as the fallback. I’ll be testing this in production as a private Play Store application. Come to this session to learn more about how to make the most of Antigravity for Android development.
