ZheHacK/WhatsappHack ? reverse-engineered prompt

Build me an Android app that helps me manage my own WhatsApp media in one place.

I want it to scan the phone for WhatsApp photos, videos, audio, and documents, then show them in a simple gallery with easy filters so I can browse, search, and clean up files I do not need. It should let me open items, share them, copy them to another folder, and back them up safely. If it needs a setup flow or permissions screen, make it clear and easy to understand.

Keep the app lightweight and simple to use, with a basic modern look. If you need to check current Android docs or best practices while building it, go ahead and look them up online. Please make it work as a real project I can open, run, and build from Android Studio without extra hassle.
