1.9. Test-Driving the Doodlz App in an Android Virtual Device (AVD)

In this section, you’ll run and interact with your first Android app. The Doodlz app allows you to drag your fingers on the screen to “paint.” You can control the brush sizes and colors using options provided in the app’s options menu. There is no need to look at the app’s code—you’ll build the app and study its code in Chapter 7.

The following steps show how to import the app’s project into Eclipse and how to test-drive the app in the Nexus 4 Android Virtual Device (AVD) that you set up in the Before You Begin section following the Preface. Later in this section, we’ll also discuss how to run the app on a tablet AVD and on an Android device. When the app is running in an AVD, you can create a new painting by “dragging your finger” anywhere on the canvas. You “touch” the screen by using the mouse.
