when you’re so ansures to run your first anxious app using eclipse ?, then I’m here to tell you, you’re not alone in this. I run into this problem with my first android setup . However, after a couple of google search,I found a solution to this problem.

Android Developer Tools

ADT (Android Developer Tools) is a plugin for Eclipse that provides a suite of tools that are integrated with the Eclipse IDE. It offers you access to many features that help you develop Android applications quickly. ADT provides GUI access to many of the command line SDK tools as well as a UI design tool for rapid prototyping, designing, and building of your application’s user interface.Because ADT is a plugin for Eclipse, you get the functionality of a well-established IDE, along with Android-specific features that are bundled with ADT.

Android apps are developed with Java—the world’s most widely used programming lan-
guage. Java was a logical choice for the Android platform, because it’s powerful, free and
open source. Java Development Environment (JDE) serves as the development platform for android application. Failure to set JDE for android development platform runs into the error message above.
