Getting the Android Development Environment Working

I was setting up the development environment for the Android version of our new product when I get the following error:

Cannot complete the install because one or more required items could not be found.
  Software being installed: Android Development Tools 0.9.9.v201009221407-60953 (com.android.ide.eclipse.adt.feature.group 0.9.9.v201009221407-60953)
  Missing requirement: Android Development Tools 0.9.9.v201009221407-60953 (com.android.ide.eclipse.adt.feature.group 0.9.9.v201009221407-60953) requires 'org.eclipse.wst.sse.core 0.0.0' but it could not be found

It turns out you need some optional parts of  Eclipse.

So in Eclipse under Help > Install New Software make sure you reference the correct version of Eclipse as well as the ADT toolkit, i.e.: http://download.eclipse.org/releases/indigo.

The link that helped me was: http://stackoverflow.com/questions/4249695/adt-requires-org-eclipse-wst-sse-core-0-0-0-but-it-could-not-be-found

Good Luck
