Splitting Android MVVM ViewModel | SOLID for Android - Part 6 | Finale
In this tutorial, we dive into the final steps of refactoring the ViewModel in Android to ensure compliance with SOLID principles. We'll focus on separating concerns between the UI and business logic by refactoring the existing ViewModel into two distinct ViewModels: one for UI state management and another for business operations. This process improves code maintainability, testability, and overall structure.
Key topics covered:
Refactoring ViewModel for better separation of concerns
Creating a `CountryUIViewModel` for UI logic
Moving business logic to `CountryOperationViewModel`
Managing UI state, including loading indicators and data binding
Ensuring clean code architecture through a bottom-up refactoring approach
Key principles of SOLID applied in Android development
By the end of this video, your project should have improved modularity and better alignment with SOLID principles, making the code easier to maintain and extend in the future.
