Refactoring MVVM Repository for SOLID compliance | SOLID with Android - Part 5
In this tutorial, we dive deeper into Android development concepts, focusing on refining the repository pattern by addressing key issues and violations of SOLID principles like SRP (Single Responsibility Principle), OCP (Open/Closed Principle), and DIP (Dependency Inversion Principle). We will demonstrate how to decouple the repository from a static utility function fetching data from a local JSON file and introduce flexibility by leveraging interfaces.
You’ll learn how to:
Implement the CountryListServiceProvider interface for multiple data sources (local JSON, API, and database).
Refactor your repository to make it compliant with SOLID principles.
Use Retrofit to fetch data from an API while maintaining flexibility and abstraction in your codebase.
Handle ViewModel UI state management separately from business logic to prevent SRP violations.
By the end of this video, you'll be able to create more maintainable and scalable Android applications using best practices. Don't forget to check out the next video where we will further refactor the ViewModel to adhere to these principles.
