Architecture Pattern

An architectural pattern in software development is a structural guide that helps developers design scalable, maintainable, and efficient applications. For Android app development, applying an architectural pattern is a common practice as it organizes the project into distinct layers, making the code modular and testable. This approach ensures better maintainability and allows seamless addition of new features in the future. MVC (Model-View-Controller) and MVVM (Model-View-ViewModel) are two widely adopted patterns by developers.

The MVC pattern divides the application into three components. The Model manages application data and interacts with the database or network. The View is responsible for the user interface, presenting data from the Model and facilitating user interaction. The Controller connects the Model and View, handling core logic and updating the Model based on user input.

In contrast, the MVVM pattern offers a modern approach, improving upon MVP. It separates data presentation (View) from core business logic. The Model abstracts data sources, the View observes and interacts with the ViewModel, and the ViewModel bridges the gap between View and Model by exposing data streams. These patterns enhance code clarity, testing, and scalability, making them vital tools for modern Android app development.
