title: Android failed to export application
body: <p>I have problem when trying to sign my application in release mode from over two/three days now. I've tried everything which I find as an information in internet/stackoverflow and nothing worked for me. I've update my whole <code>SDK</code>, update <code>proguard</code> to 4.7 version, checked for jar files and conflict packages, but can't find any solution. I have included library to my main project,but 'till now I did not have any problems with signing my application. </p>
  
  <p>Any ideas what else I can try so I can solve this problem, because I'm still reading some information over internet and still can't find any solution.</p>
  
  <p>P.S. I did not have problem with building debug version and running on device. The only problem I get is only when I try to sign my application on release mode and I get <code>Failed to export application</code> error.</p>
