Learners will develop, implement, and evaluate a fully functional Android calculator application using Kotlin and Android Studio. By the end of this course, learners will be able to configure Android project structures, modify Activities, design interactive user interfaces, integrate Gradle dependencies, and implement core calculation logic to produce a working mobile application.

This hands-on, project-based course guides learners step by step through the complete Android app development workflow. Starting with understanding the project setup and Activity lifecycle, learners progressively build confidence by creating UI components such as buttons, handling user interactions, and refining application logic in the MainActivity. The course concludes with validating the final output, ensuring the calculator functions correctly in a real Android environment. What makes this course unique is its end-to-end project focus. Rather than isolated concepts, learners work on a single practical project that mirrors real-world Android development practices. This approach helps learners translate theory into application-ready skills. Whether learners are new to Android or strengthening their Kotlin expertise, this course equips them with practical experience essential for building interactive Android applications and advancing mobile development skills.
