Understanding the Single Responsibility Principle in Kotlin Android with Jetpack Compose

Introduction

The Single Responsibility Principle (SRP) is one of the core SOLID principles in object-oriented programming. Introduced by Robert C. Martin, SRP means that a class should have only one reason to change.
It should handle just one task or responsibility. While the idea is simple, following it greatly impacts how easy your code is to maintain, test, and scale.

The SOLID Foundation

Before diving deeper into SRP, it’s worth noting that it’s just one of the five SOLID principles:

• S: Single Responsibility Principle
• O: Open/Closed Principle
• L: Liskov Substitution Principle
• I: Interface Segregation Principle
• D: Dependency Inversion Principle

These principles offer a solid foundation for building robust, maintainable, and scalable software architectures. In this article, however, we’ll focus specifically on the Single Responsibility Principle (SRP) and how it applies to Kotlin Android development.
