mgks/android-smartwebview ? reverse-engineered prompt

Build me an Android app that wraps my website in a clean WebView and feels like a real hybrid app, not just a browser page.

I want the main site URL to be easy to change from one config file, with an offline fallback page when there’s no internet. Please include support for file uploads, camera capture, location access, content sharing from other apps, downloads, printing, and push notifications if Firebase is added later. It should also have a simple plugin style setup so features like biometric lock, QR scanning, ads, toast messages, and native dialogs can be turned on without rewriting the main app.

Make the app easy to customize, with a fullscreen mode and a more standard navigation mode. Keep the code clean and modern, and leave clear places where I can plug in my own website and settings. If you need to check current Android or Firebase docs while wiring things up, go ahead.
