ADT installation Error

I am using Eclipse 3.5 (Galileo), and I'm trying to install ADT plugin from remote as well as local archive. It is not installing. I am getting the following error for both remote as well local:

Android Development Tools 0.9.5.v200911191123-20404 (com.android.ide.eclipse.adt.feature.group 0.9.5.v200911191123-20404)
Missing requirement: Android Development Tools 0.9.5.v200911191123-20404 (com.android.ide开发者_StackOverflow社区.eclipse.adt.feature.group 0.9.5.v200911191123-20404) requires 'org.eclipse.gef 0.0.0' but it could not be found

How do I solve this? Thanks in Advance

You'll need to install the eclipse graphical editing framework. You can install directly from within eclipse using the release site

I just went through the experience of installing the Android SDK and ADT Plugin. Below is a link to how to setup the ADT Plug-in.

The simplest solution is to install eclipse INDIGO version, That contains every requirements you met. Good luck.

Something I have to say is: INDIGO is much more faster than galileo!! So upgrade it without hesitate!
