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.

It acts as an abstraction layer over the data access.

It allows us to use dependency injection.


It holds the business login for the view.

It is the only class that is in control of the data.


It centralizes data access into a single class.


It captures original data from the web and decides where to put it. It either caches it or provides it to the UI.


What is not the reason why the repository is known as the single source of truth (SSOT)?

It dispatches data when the device is offline.


It connects directly to the `ViewModel` and emits values.


It checks if the cached values are sufficiently recent.

To define database interactions that include a variety of query methods.

To act as a reference class for the database when `Room` generates its implementations.
