Why we are using MVVM?

Why MVVM with Clean Architecture? MVVM separates your view (i.e. Activity s and Fragment s) from your business logic . MVVM is enough for small projects, but when your codebase becomes huge, your ViewModel s start bloating. Separating responsibilities becomes hard.

This is why single page applications work very well with ViewModels.15 Eki 2017
