title: Can't export apk files in flash builder
body: <p>I'm developping a mobile application in Flash builder. So in Flash Builder Burrito , I was using the Flex Hero SDK 4.5.0 but they currently realesed the Flex4.5.0.20967.</p>
  
  <p>I downloaded the zip file ( <a href="http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4.5" rel="nofollow">http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4.5</a>)</p>
  
  <p>I extracted it into a map on my C:\ drive.
  Then I opened my flash builder burrito. Added him by (Window>Flash Builder>Installed Flex SDK's. I his add and added my location.</p>
  
  <p>This went very well. I changed my code with the new commands.</p>
  
  <p>Next I wanted to test on my android phone but now my problem:
  I can't make any apk files anymore. Does anybody knows how this comes and have a solution for this?</p>
  
  <p>Hope someone can help me.</p>
  
  <p>Kind regards,</p>
