In one of my Android projects, I used the MVVM (Model-View-ViewModel) architecture. It helps separate presentation logic from business logic, making maintenance and testing easier.

  • Model is responsible for data handling (e.g., repositories, databases).
  • View consists of UI components (Activity, Fragment) that display data.
  • ViewModel contains logic for preparing data for the View and interacts with the Model.

To connect the View and ViewModel, I used LiveData, which automatically updates the UI when data changes.

A simple example of a ViewModel in Kotlin:

class UserViewModel : ViewModel() {
    private val userRepository = UserRepository()
    val userData: LiveData<User> = userRepository.getUserLiveData()
}

This approach improves code readability and facilitates application scaling.
