An Android project contains all the files that comprise the source code for your Android app. The Android SDK tools make it easy to start a new Android project with a set of default project directories and files.
This lesson shows how to create a new project either using Eclipse (with the ADT plugin) or using the SDK tools from a command line.
Note: You should already have the Android SDK installed, and if you’re using Eclipse, you should also have the ADT plugin installed (version 21.0.0 or higher). If you don’t have these, follow the guide to Installing the Android SDK before you start this lesson.
