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.

Chapter 11: Creating Infinite Lists with Jetpack Paging and Kotlin Flow

In the previous chapters, we built the great Restaurants App that displayed content from our own backend. However, the number of restaurants displayed in the Restaurants App was fixed, and the user was only able to browse through the few restaurants that we added to our Firebase database.

In this chapter, we will understand how pagination can help us display large datasets of items without putting pressure on our backend and without huge network bandwidth consumption. We will create the impression of an infinite list of items inside a new app that we will be working on called the Repositories App, and we will achieve that with the help of yet another Jetpack library called Paging.

In the first section, Why do we need pagination?, we will explore what data pagination is and how it can help us break large datasets into pages of data, thereby optimizing the communication between our app and the backend server...
