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.

|http://download.eclipse.org/webtools/updates||Web Tools Platform / Eclipse XML Editors and Tools|
That should do it for you!
If you are on karmic and getting the error, The artifact file for osgi.bundle,org.eclipse.ant.ui,3.4.1.v20090901_r35 1 was not found.
This will fix: sudo apt-get install eclipse-pde eclipse-jdt
