Clean Architecture: The Key to Modular and Testable Android Apps

<p>Imagine you&rsquo;re building a house. In Clean Architecture, your codebase is like that house. It&rsquo;s organized in distinct layers, each with its own purpose and responsibilities. Just like a house has an outer shell, rooms, and inner workings, Clean Architecture has layers: Presentation (UI), Domain (business logic), and Data (storage and external services). The key idea is to keep these layers independent so that changes in one layer don&rsquo;t affect others.</p> <h1>What is MVVM in Android with example?</h1> <p>MVVM stands for Model-View-ViewModel, and it&rsquo;s a design pattern used in software development, particularly in the context of building user interfaces for applications, including Android apps. MVVM is designed to help separate the concerns of an application&rsquo;s UI, business logic, and data manipulation, making the codebase more modular, maintainable, and testable.</p> <p>Imagine you&rsquo;re making a to-do list app. The Model represents your tasks, the View is the UI displaying those tasks, and the ViewModel manages the data and interactions. So, when you check off a task in the UI, the ViewModel updates the Model, and the UI automatically reflects the change. This separation makes your code more maintainable and testable.</p> <p><a href="https://pinarturgut09.medium.com/clean-architecture-the-key-to-modular-and-testable-android-apps-6f8ab0ccaf89">Read More</a></p>
