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.

Further reading

Working with ViewModels and handling state changes in Compose represent two essential topics for reliable projects. Let's see what other subjects revolve around them.

Exploring ViewModel with runtime-provided arguments

In most cases, you can declare and provide dependencies to your ViewModel inside the constructor, at compile time. In some cases, though, you might need to initialize a ViewModel instance with a parameter that's only known at runtime.

For example, when we're adding a composable screen that displays the details of a restaurant, instead of sending the ID of the target restaurant from the composable to ViewModel through a function call, we can provide it directly to the ViewModel constructor through ViewModelFactory.

To explore the process of building a ViewModelFactory, check out the following Codelab: https://developer.android.com/codelabs/kotlin-android-training-view-model#7.
