The icon for the application is set here and you can upload your own icon, and the default is the Android Classic Green robot icon. Click Next here to select the activity style, the most basic of course is blank activity. And then into Eclipse. We don't need to add any code manually, and the Engineering Wizard automatically creates the underlying files and directory structure needed for Android projects in the background based on the Android engineering information that the user fills in.
