Can you tell about your experience in developing and implementing architectural solutions based on MVP?

In MVP (Model-View-Presenter) architecture, I divided responsibilities among layers:

• Model — responsible for data and business logic.
• View — displays data and interacts with the user.
• Presenter — acts as an intermediary between Model and View, handling display logic and user actions.

In projects, I implemented MVP to improve testability and maintainability of the code. For example, the Presenter does not contain Android dependencies, which allows writing unit tests without an emulator.

An example of a simple Presenter:

interface View {
    fun showData(data: String)
    fun showError(message: String)
}

class Presenter(private val view: View, private val model: Model) {
    fun loadData() {
        try {
            val data = model.getData()
            view.showData(data)
        } catch (e: Exception) {
            view.showError(e.message ?: "Error")
        }
    }
}

This approach helps separate UI and logic, making the application easier to support and extend.
