title: Android Studio can't access SDK Manager
body: <p>I have just downloaded and installed Android studio 0.4.2 and loaded an android project.  This project gives me this error:</p>
  
  <pre><code>Cause: failed to find target android-17
         Please install the missing platform from the Android SDK Manager.
  </code></pre>
  
  <p>so great, I will now go into the SDK manager, and get the missing platform.  The only problem is, I cannot access the SDK Manager.  The SDK manager button is grayed out and when I go to tools, there is no option for android, so I can't go to toold
  
  <p>Any ideas on how I can fix this problem?  I have used Eclipse with ADT before and never had this issue...</p>
