Overview of this book

With Jetpack libraries, you can build and design high-quality, robust Android apps that have an improved architecture and work consistently across different versions and devices. This book will help you understand how Jetpack allows developers to follow best practices and architectural patterns when building Android apps while also eliminating boilerplate code. Developers working with Android and Kotlin will be able to put their knowledge to work with this condensed practical guide to building apps with the most popular Jetpack libraries, including Jetpack Compose, ViewModel, Hilt, Room, Paging, Lifecycle, and Navigation. You'll get to grips with relevant libraries and architectural patterns, including popular libraries in the Android ecosystem such as Retrofit, Coroutines, and Flow while building modern applications with real-world data. By the end of this Android app development book, you'll have learned how to leverage Jetpack libraries and your knowledge of architectural concepts for building, designing, and testing robust Android applications for various use cases.

Exploring pagination with Jetpack Paging

To implement an infinite list of repositories in our Repositories App, we must find a way to request more repositories as the user scrolls through the existing list and reaches its bottom, thereby adding new elements on the fly. Instead of manually deciding when the user is approaching the bottom of the current list of repositories and then triggering a network request to get new items, we can use the Jetpack Paging library, which hides all this complexity from us.

Jetpack Paging is a library that helps us load and display pages of data from a large set of data, either through network requests or from our local data storage, thereby allowing us to save network bandwidth and optimize the usage of system resources.

In this chapter, for simplicity, we will use the Paging library to display an infinite list of repositories obtained from a network source (that is, the GitHub Search API), without involving the local cache.
