Changes

The first step in the process of generating a signed application APK file involves changing the build variant for the project from debug to release. This is achieved using the Build Variants tool window which can be accessed from the tool window quick access menu (located in the bottom left hand corner of the Android Studio main window as shown in Figure 54-1).
