android/nowinandroid ? reverse-engineered prompt

Build me a polished Android app like Now in Android, using Kotlin and Jetpack Compose.

I want it to help developers keep up with Android news, videos, articles, and other official updates. The app should have a clean modern interface with a personalized For You screen, a way to browse topics, topic detail pages, and the ability for users to follow topics they care about. When new content matches their followed interests, the app should be able to notify them.

Make it feel like a real production Android app, not a demo. Use sensible Android best practices, a modular structure, local demo data so it can run immediately without a backend, and keep the code easy to learn from. Include basic tests where they make sense, and make sure it opens and runs from Android Studio with the normal demo debug setup.

Look up current Android docs online if you need to.
