Have you had experience implementing the MVP pattern in projects?

Yes, I have experience implementing the MVP (Model-View-Presenter) pattern in Android projects. In this pattern, the View is responsible only for displaying data and interacting with the user, the Presenter contains the business logic and manages data, and the Model is the data layer and business rules.

Example:

interface LoginView {
    fun showLoading()
    fun hideLoading()
    fun showError(message: String)
    fun navigateToHome()
}

class LoginPresenter(private val view: LoginView, private val userRepository: UserRepository) {
    fun login(username: String, password: String) {
        view.showLoading()
        if (userRepository.authenticate(username, password)) {
            view.navigateToHome()
        } else {
            view.showError("Invalid username or password")
        }
        view.hideLoading()
    }
}

This approach simplifies testing and code maintenance by separating UI from logic.
