title: XAPK File Validation Failed - APK Expansion Files
body: <p>I am using the expansion files demo given in the sdks and am placing the obb file on the SD Card at the following location:</p>
  
  <pre><code>/Android/obb/package-name/package-name/main.versioncode.package-name.obb
  </code></pre>
  
  <p>But i get the following error:</p>
  
  <blockquote>
    <p>XAPK File Validation Failed</p>
  </blockquote>
  
  <hr>
  
  <p>For generating the <code>.obb</code> files this is the procedure i have followed :</p>
  
  <p>1) copy all the images to a folder named <code>main.versioncode.package-name.obb</code> and then zip that file.</p>
  
  <p>2) remove .zip file extension and place it in this <code>/Android/obb/package-name/myobbfile.obb</code></p>
  
  <p>Is this the correct way of doing it?</p>
