In this final chapter of the book, we started learning how to create different builds of our applications, combining build types with product flavors to obtain build variants.

After that, we learned how to monetize our app, adding different types of adverts and explaining the key points of advertisement monetization.

We also exported the app, obfuscated and signed with a release certificate, from Android Studio and from the command line using Gradle.

To finish, we uploaded and published our app in Play Store.
