I have Eclipse (Indigo Service Release 1, Build id: 20110916-0149) running on Win XP.
I\'ve added https://dl-ssl.google.com/android/eclipse/ and installed 4 plugins
Well i had this issue as well, but what i see its one componment that isnt on the google servers (at least for indigo) com.android.ide.eclipse.adt_20.0.0.v201206242043-391819.jar you need download the ADT from google server ADT 20.00 and the install new software in help menu as always In the Add Site dialog, click Archive. Browse and select the downloaded zip file. Enter a name for the local update site (e.g., "ADT-20.0.0.zip") in the "Name" field. Click OK. and done choose the ADT developer that i bet you dont have installed that should fix the problem ;)
