title: Android - PhoneGap application (keystore file error)
body: <p>I am developing a PhoneGap application through Eclipse on the Android platform. My code is ready and run perfectly.</p>
  
  <p>Now, I already created a signed <a href="http://en.wikipedia.org/wiki/APK_%28file_format%29" rel="nofollow noreferrer">APK</a> file in release mode. So, when I uploaded this keystore file on "<strong>build.phonegap.com</strong>", and clicked on <kbd>Submit key</kbd>, I got an error like this:</p>
  
  <blockquote>
    <p>Error: extension did not match expected (keystore)"</p>
  </blockquote>
  
  <p>I don't know what is going wrong in this. Is there a proper solution?</p>
