0xRahad/PhotoMo-VideoEditor — reverse-engineered prompt

I want an Android app in Java that works like a simple photo to video maker. Use this project as the starting point and finish it into something I can open in Android Studio, run, and tweak for myself.

The app should let someone choose photos from their phone, put them into a slideshow style video, preview the result, and save the final video to the device. If there are already editing pieces in the repo, keep them and make the whole flow feel complete and usable. The UI should be simple and easy to understand, not developer looking.

Please fix anything missing or broken so it builds cleanly and actually works on a modern Android device. If the current code already has extra video editor features, keep them instead of stripping things out. I would also like sensible permissions handling, basic error messages, and a clear home screen so a normal user can figure it out. Look up current Android docs online if you need to.
