Differences Between Android Architecture Patterns: MVC, MVP, and MVVM

1. MVC (Model-View-Controller):

   • What it is: This pattern splits an app into three main parts.
   • How it works: The View shows what the user sees and interacts with. The Controller processes that interaction and updates the Model, which holds the data.
   • Who uses it: About 25% of app developers like MVC because it’s easy to understand.

2. MVP (Model-View-Presenter):

   • What it is: This pattern is like MVC but has a Presenter that takes care of how the app looks and behaves.
   • How it works: The View stays simple and only shows the interface. It sends user actions to the Presenter. The Presenter then updates the Model and tells the View what to show.
   • Who uses it: Around 35% of developers like MVP because it keeps the parts of the app more organized.

3. MVVM (Model-View-ViewModel):

   • What it is: This pattern adds a ViewModel that connects the View directly to the Model.
   • How it works: The ViewModel looks after data that the View needs, making coding easier and less messy.
   • Who uses it: This option is becoming more popular, with about 40% of developers choosing MVVM, especially when using Jetpack libraries.

In summary, MVC is simple to use, but MVP and MVVM help keep apps better organized and easier to test. These days, MVVM is the most popular choice among developers.
