I want a lightweight calculator app built exclusively for Android. It only has to cover the everyday arithmetic functions—add, subtract, multiply and divide—display results instantly, and look clean on current Android versions. The code must compile without modification in the latest Android Studio release and follow standard best practices (modular structure, clear naming, concise comments). Feel free to use either Kotlin or Java; just be consistent throughout. Deliverables • Full, well-commented source code • Debug-build APK for quick testing • Brief read-me explaining how to import, build and run the project in Android Studio If you can keep the interface minimal, the footprint small, and the workflow straightforward, this job will be a quick win for both of us.
