To get the most out of this book

You'll need the Android Studio IDE installed on your computer (version Arctic Fox 2020.3.1 Patch 3 or above) and Java 8 to be installed. Using later versions of Java such as Java 11 might cause errors when building some of the exercises. Knowing how to trigger builds on an emulator or device and Gradle Synchronizations from Android Studio is recommended before attempting the exercises presented in the book.

You can expand on the final exercise of the book by optimizing the way the data is loaded, introducing in-memory caches, or integrating new network calls to fetch additional data for the users. You can also improve the instrumentation testing by adding interaction with the list of data and opening new screens and asserting that the correct data is displayed.

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book's GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
