Following the posted instructions for Eclipse 3.6.1 Classic and Android SDK, ADT (where OS 2.3 is the most current) misses a few steps. Everything seems to work up until the point of loading the ADT in Eclipse. Prior to doing this add the following dependency sites to the list and enable them so that the ADT installer will pickup all the dependencies (thanks MissKaho for the concise list). Eclipse GEF - download.eclipse.org/tools/gef/updates/releases/ Eclipse EMF - download.eclipse.org/modeling/emf/updates/releases/ Eclipse GMF - download.eclipse.org/modeling/gmf/updates/releases Eclipse Webtools - download.eclipse.org/webtools/updates/ Google eclipse Plugin - dl.google.com/eclipse/plugin/3.6
