'required items could not be found' error when installing ADT plugin

Question

Cannot complete the install because one or more required items could not be found. Software being installed: Android Development Tools 12.0.0.v20110628192

Answer 1

Have had the same problem a few times. You need to add the following urls to the "Available Software Sites" of your eclipse installation:

• http://download.eclipse.org/releases/indigo
• http://download.eclipse.org/eclipse/updates/3.7

That should fix it.

If not, see my install paths, and add as needed:

Also, make sure you tick the box on install that says "Contact all update sites during install to find required software".
