Android offers a custom plugin for the Eclipse IDE, called AndroidDevelopment Tools (ADT). This plugin provides a powerful, integratedenvironment in which to develop Android apps. It extends the capabilitiesof Eclipse to let you quickly set up new Android projects, build an appUI, debug your app, and export signed (or unsigned) app packages (APKs) for distribution.

Note:If you have been using Eclipse with ADT, be aware that Android Studio is now the official IDEfor Android, so you should migrate to Android Studio to receive all thelatest IDE updates. For help moving projects,see Migrating to AndroidStudio.

You should install the ADT pluginonly if you already have an Eclipse installation that you want to continue using.Your existing Eclipse installation must meet these requirements:

• Eclipse 3.7.2 (Indigo) or greater

  Note: Eclipse 3.6 (Helios) is no longersupported with the latest version of ADT.

• Eclipse JDT plugin (includedin most Eclipse IDE packages)
• JDK 6 (JRE alone is not sufficient)
• Not compatible with GNU Compiler for Java (gcj)
