wuhaoyu1990/MagicCamera — reverse-engineered prompt

Build me an Android camera app like a beauty filter selfie camera. I want it to show live camera preview with a bunch of real time filters, around 40 or more like the original project, and let people take photos and record video with the selected effect applied. It should also include a simple image editing screen for photos with face beauty tools, especially smooth skin and skin whitening, since that seems to be a core part of the app.

Please make it feel usable and modern, with a clean camera screen, easy filter switching, capture and record buttons, and a basic editor flow after picking or taking an image. If the current codebase has the camera part in Android Studio and the editor stuff in the older Eclipse project, merge or adapt what makes sense so the app is actually runnable. Keep the core behavior faithful to the original repo and screenshots. If you need to, look up current Android camera and graphics docs online and update anything outdated so it builds and runs today.
