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.

Mastering MVVM Architecture in Android Development using Kotlin

A `ViewModel` stores and manages UI-related data.


A `ViewModel` has observables that help expose data to the activity or fragment.e  `LiveData` is an observable used by the `ViewModel`.


A `ViewModel` can act as coroutines to handle multithreading using suspend functions.


Which statement about the ViewModel is false?


Which statement about the ViewModel is false?


Which method is not a part of the activity lifecycle?

Which method is not a part of the activity lifecycle?

It uses very low memory and network bandwidth since a small amount of data is fetched at a time.


Content from the remote server is loaded faster.


Paging easily works in conjunction with `LiveData` and ViewModel to observe and update data.


Refresh and retry capabilities do not work efficiently with Pagination.


Pagination is a part of the Android Jetpack feature used to load data in chunks instead of loading a whole set of data from the server. What is not a benefit of using the Paging library in our project?
