In Android Studio v3.1.3 (the latest version) the Configure Activity screen is different from what is show in Chapter 7. First of all Hierarchical Parent is no longer present (this may be because this is the first activity in the app). Second, when you change the Layout Name to activity_list it automatically renames the Activity Name to ListActivity. You can go back and rename it to MainActivity after changing the Layout Name.
