title: installing ADT 17 on windows 7 and eclipse indigo, Everything works fine but there is no Android type project in New Project
body: <p>Today I installed the new Android SDK tools revision 17. When I started eclipse, it said that you should upgrade your ADT. I downloaded the latest version ZIP file (ADT-17.0.0.zip) and I followed the Eclipse instructions to install ADT. Everything goes fine (as I expected) but at the end I was unable to see Android in preferences and also android project in New Project wizard. 
  I am using Eclipse Indigo and Windows 7.</p>
  
  <p>Any idea? </p>
