An Activity should be as dumb as possible. This includes our Activitys, Fragments, and ViewModels. You are free to choose whatever project structure suits you. I like to group project files based on features. It adds a lot of extra classes, so it’s not ideal for low-complexity projects.Įven within the Android app architecture we’re using, there are many ways to structure your file/folder hierarchy. How all the layers work together may take some time to understand, especially if you are coming from patterns like simple MVVM or MVP. It has a slightly steep learning curve.Your team can add new features even more quickly.The project is even easier to maintain.The package structure is even easier to navigate.Your code is further decoupled (the biggest advantage.).Your code is even more easily testable than with plain MVVM.But since Android Architecture Components already provides a built-in ViewModel class, we are going with MVVM over MVP-no MVVM framework required! Advantages of Using Clean Architecture Note: You can combine Clean Architecture with the model-view-presenter (MVP) architecture as well. It clearly abstracts the logic of the actions that can be performed in your app. It goes one step further in separating the responsibilities of your code base. MVVM with Clean Architecture is pretty good in such cases. Separating responsibilities becomes hard. MVVM is enough for small projects, but when your codebase becomes huge, your ViewModels start bloating. Activitys and Fragments) from your business logic. We are going to see how this architecture can be used to write decoupled, testable, and maintainable code. In this article, we are going to combine MVVM (Model-View-ViewModel or sometimes stylized “the ViewModel pattern”) with Clean Architecture. This isn’t just an Android MVVM tutorial. If you don’t choose the right architecture for your Android project, you will have a hard time maintaining it as your codebase grows and your team expands.
