The course focuses on the MVVM (Model-View-ViewModel) architecture in Android development using Kotlin. The MVVM is widely recommended due to its robustness, scalability, and ease of maintenance. It is a valuable skill to have for building high-performance Android applications.

Firstly, you will learn the basics of MVVM architecture and its advantages over other approaches to Android development. Then, you'll start from scratch and create layouts for a news application. Next, you'll use the Retrofit and OkHttp networking libraries and get to familiarize yourself with APIs. You'll get hands-on experience in storing data locally via the Room library. Finally, you'll be introduced to both the repository and ViewModel patterns, as well as how to work with the Paging library and deliver data to our fragments.

By the time you’re done with the course, you’ll be able to use MVVM in your Android projects, interact with APIs, store data locally, and implement pagination.

# What is an architecture?

Architecture is basically the structure of an application. When developing software, the most essential thing to learn before beginning is how we’re going to organize our code in a way that best suits our product, and that’s where architecture comes in.

# MVVM
**Model-View-ViewModel (MVVM)** is an architecture that’s commonly used by Android developers and is recommended by Google. MVVM was introduced by Microsoft architects to simplify design patterns while developing software, primarily to separate the frontend and backend to reduce the dependency of views with other components. The MVVM design pattern was employed to solve dependency and separation of concerns problems, and to build maintainable code that’s easier to test and adapts to changes quickly.
