google/iosched ? reverse-engineered prompt

Build me an Android app for a developer conference like Google I/O.

I want people to be able to browse the event schedule, filter sessions by type and topic, open a detail page for each event, star the ones they like, and reserve spots where that makes sense. It should also have a map for the venue, a home screen with useful conference updates, and an info section with practical attendee guidance.

Make it feel polished and easy to use, with offline friendly behavior if possible, and keep user data like stars and reservations synced when the network is available. Use Kotlin and modern Android patterns, with a clean, well organized codebase. If you need to look up current docs online to make the app feel up to date, go for it.

I’d also like it to support a staging mode so it can run without real backend credentials, and please include basic tests so the main flows are covered.
