ReVanced/revanced-manager ? reverse-engineered prompt

Build me an Android app like ReVanced Manager. I want a clean mobile app that helps people download supported Android apps, choose patches for them, apply those patches, and then manage the patched apps afterward.

The app should feel simple for regular users, with clear screens for available apps, patch selection, progress while patching, finished results, and settings. It should also let users manage things like signing, themes, updates, downloaded files, and patch related options. Make the interface modern and friendly, with a ReVanced style manager feel rather than a developer tool.

Use Kotlin for Android and make it production ready enough to build and install. Include sensible error messages, loading states, and a basic documentation page or guide inside the project so someone can understand how to build and use it. If you need current Android or ReVanced patcher details, look up the latest docs online.
