ferhatozcelik/Offline-Chat ? reverse-engineered prompt

Build me an Android app for offline chat that works without internet on devices connected to the same Wi Fi network.

It should automatically find nearby devices, show them in a simple list, let one device host a chat room and let the others join it, then exchange messages in real time over the local network. I want the chat history and recently seen rooms saved on the phone so they can be opened again later. Keep the app clean and easy to use, with a simple home screen, a join flow, and a chat screen that feels fast and lightweight.

Please use a modern Android setup with a clear separation between the UI and the data logic, and make sure the project is ready to build and run. If you need to look up the current Android docs for any details, go ahead.
