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.

## Introduction to pagination
The Paging 3 library is a useful tool for implementing infinite scrolling in a `RecyclerView` by dividing a large dataset into smaller chunks and gradually loading them into the view. This allows for smooth and efficient data loading as the user scrolls through the list.

Additionally, Paging 3 simplifies the process of loading data from both local databases and network sources.


### Benefits of pagination

* The Paging library is designed to be resource-efficient because of its built-in caching system. This system helps to improve the speed of data loading and retrieval, leading to a smoother overall experience for the user. As a result, the library is able to use system resources efficiently, ensuring that performance remains optimal even when working with large datasets.

- The Paging library includes built-in support for error handling, which allows it to automatically handle issues that may arise during data loading or retrieval. This support includes the ability to refresh the data or retry failed requests, ensuring that the user experience is not disrupted by transient errors. This helps to ensure that the data displayed in the `RecyclerView` is always accurate and up-to-date.

- The `RecyclerView` adapter included with the Paging 3 library is highly flexible when it comes to pagination, allowing it to automatically load new data and make requests as the user approaches the end of the current page. This ensures that the data displayed in the `RecyclerView` is always current and up-to-date, providing a seamless experience for the user as they navigate through the list.
