90.1 The Release Preparation Process

Up until this point in the book, we have been building application projects in a mode suitable for testing and debugging. Building an application package for release to customers via Google Play, on the other hand, requires that some additional steps be taken. The first requirement is that the application be compiled in release mode instead of debug mode. Secondly, the application must be signed with a private key that uniquely identifies you as the application’s developer. Finally, the application must be packaged into an Android App Bundle.

While each of these tasks can be performed outside of the Android Studio environment, the procedures can more easily be performed using the Android Studio build mechanism as outlined in the remainder of this chapter. First, however, it is important to understand a little more about Android App Bundles.
