title: ADT needs to update but find no update
body: <p>Today I installed API8 from the SDK manager, previously I only had been working with API14. After the SDK manager was done, and upon restarting ADT I got this error:</p>
  
  <blockquote>
    <p>This android SDK requires Android Developer Toolkit version 21.1.0
    and above. Current version is 21.0.1.2012-12-6-2-58.</p>
  </blockquote>
  
  <p>So I click to find updates but I get "no updates found".</p>
  
  <p><strong>I did the following:</strong></p>
  
  <ul>
  <li><p>Used the SDK manager to re-install android SDK tools (rev 21.1).</p></li>
  <li><p>Used the SDK manager to re-install API8 and API14.</p></li>
  </ul>
  
  <p>Still no go :(</p>
