Changes

On the form factors screen, enable the Phone and Tablet option and set the minimum SDK setting to API 24: Android 7.0 (Nougat). Continue through the remaining setup screens, requesting the creation of an Empty Activity named FirstActivity with a corresponding layout file named activity_first.

The user interface will need to be comprised of a single Button and a TextView. Within the Project tool window, navigate to the activity_first.xml layout file located in app -> res -> layout and double-click on it to load it into the Layout Editor tool. With the tool in Design mode, select and delete the Hello World! TextView object.

Compile and run the app and verify that the second activity is launched when the Launch button is clicked.
