Kick off a step-by-step journey to build a modern calculator app in Android Studio using Kotlin, design a beautiful user interface, and write clean code for a fully functional app.
Download and install Android Studio to begin building apps, then select Android Studio and Android Virtual Device, choose the installation location, and complete the setup.
Create a new Android Studio project with an Empty Activity, set the app name and unique package name, choose Kotlin and default minimum SDK, switch to Groovy DSL, then finish.
Design a custom button background in Android Studio by creating a drawable resource, defining an oval shape with a dark purple color, and adding a pressed state shape.
Design the Android Studio main screen user interface by creating calculator buttons (1–9 and 0) with a custom shape, setting IDs and text sizes, and positioning input and result views.
Initialize the main activity UI by binding input and output text views, setting input and operator strings, and wiring all buttons with IDs, including subtraction, to prepare for calculator functionality.
Implement a fully functional Android calculator by building append input, decimal handling, operator logic, and result display, with clear, percent, toggle sign, and button bindings.
Test and finalize the calculator app by identifying and fixing bugs in the multiply and number two buttons, updating the id references and the x operator in input.
