Android offers a custom Eclipse IDE plugin called Android Development Tools (ADT) designed to give you a powerful, integrated environment in which to build Android applications. It extends the capabilities of Eclipse to let you quickly set up new Android projects, create an application UI, debug your applications using the Android SDK tools, and even export signed (or unsigned) APKs in order to distribute your application. In general, developing in Eclipse with ADT is a highly recommended approach and is the fastest way to get started with Android.


If you will be developing in Eclipse with the Android Development Tools (ADT) Plugin, follow the steps to download the ADT here

Otherwise, you do not need to install Eclipse or ADT. Instead, you can directly use the SDK tools to build and debug your application.
