title: Unable to resolve target 'android-17'
body: <p>I know there are some sort-of duplicates of this, but none of the answers have been able to help me so far.</p>
  
  <p>When I open a project, I  get the following error:</p>
  
  <pre><code> [2014-01-07 14:18:00 - Permissions] Unable to resolve target 'android-17'
  </code></pre>
  
  <p>Does anybody know what may be the problem here?</p>
