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.

Why do we need pagination?

Let's say we have an Android application that allows you to explore GitHub repositories by displaying a list of projects. It does that by querying the GitHub REpresentational State Transfer (REST) application programming interface (API) with Retrofit and obtaining a fixed number of repositories inside the app. While the REST API serves the application with detailed information for each repository, the app only uses and displays the title and description of the repository.

Note

Don't confuse the Repository classes in our project architecture that abstract data logic with the GitHub repositories that are displayed in our Repositories App.

Now, let's imagine that this application retrieves and displays 20 repository elements. Because of this, the user will be able to scroll the content until the 20th element, and therefore will be able to visualize no more than 20 elements.

But what if we wanted to allow the user to explore more repositories...
