Build me a modern Android calculator app in Kotlin with XML that feels clean and polished, inspired by Samsung One UI.

I want the app to support the basic stuff people expect, like addition, subtraction, multiplication, division, percentages, decimals, delete, clear, and continuing calculations without having to reset every time. Please make the design look nice with a dark AMOLED friendly theme, smooth button animations, and a simple layout that is easy to use one handed.

It should handle bad input gracefully too, like showing a clear error state instead of crashing. Keep the experience fast and minimal, but still visually modern. If you need to check current Android or Material design docs while building it, go ahead and look them up online. Make sure the final app is ready to run in Android Studio and looks good on both the main screen and when errors happen.
