What are the differences between MVVM and MVP in Android development?

MVVM (Model-View-ViewModel) and MVP (Model-View-Presenter) are both architectural patterns used in Android development. MVVM allows for a more reactive approach, where the ViewModel holds the UI-related data and notifies the View of changes. In contrast, MVP separates the presentation logic from the UI, with the Presenter handling user interactions and updating the View.

Which one is better for large applications?

For large applications, MVVM is often preferred due to its ability to handle complex data binding and its support for reactive programming. It allows for better separation of concerns and easier testing.

Can you give an example of when to use MVP?

MVP is suitable for applications where you need clear separation between the UI and business logic, especially when the UI is complex and requires extensive user interaction. It's also beneficial when you want to facilitate unit testing of the presentation logic.

Are there any performance differences between the two?

Performance can vary based on implementation, but generally, MVVM can lead to better performance in data-heavy applications due to its efficient data binding. However, MVP can be more straightforward in terms of performance for simpler applications.
