2.4. Android Developer Tools Window

Once you’ve created the project, open its res/layout folder and double click the file activity_main.xml file so that the IDE appears as shown in Fig. 2.9. The IDE shows the Graphical Layout editor so you can begin designing your app’s GUI. In this chapter, we discuss only the IDE features we need to build the Welcome app. We’ll introduce many more IDE features throughout the book.
