Here’s the quickest way I know to get Eclipse up and running with the Android SDK plugin. To install each of these packages, go to Help->Install New Software, add the given URI as a package source, and install the given package. Eclipse may prompt you to restart after some installs.

Source Package
http://download.eclipse.org/tools/gef/updates/releases/ GEF SDK
http://download.eclipse.org/modeling/emf/updates/releases/ EMF SDK 2.5.0 (EMF + XSD)
http://download.eclipse.org/webtools/updates Web Tools Platform / Eclipse XML Editors and Tools
https://dl-ssl.google.com/android/eclipse/ Developer Tools

That should do it for you!
