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.

Creating a package structure

Our Restaurants app has come a long way. As we tried to separate responsibilities and concerns as much as possible, new classes emerged – quite a few actually.

If we have a look on the left of Android Studio, on the Project tab, we have an overview of the classes we've defined in our project.

Figure 8.5 – Project structure without any package structuring strategy

It's clear that our project has no folder structure at all – all files and classes are tossed around inside the restaurantsapp root package.

Note

The name of the root package might differ if you selected a different name for your app.

Because we've opted to throw any new class inside the root package, it's difficult to have clear visibility over the project. Our approach is similar to adding dozens of files and assets on the desktop of our PC – in time, it becomes impossible to find anything on the screen.
