title: How to modify the QtPurchasing.jar file?
body: <p>I'm using the Qt Purchase module for supscriptions under Android. Now I found that only In-App-Purchase "consumable" and "unlockable" are possible, not "subscriptions". But there would exist a hack by modifying the file.</p>
  
  <blockquote>
    <p>\5.12.1\android_armv7\jar\QtPurchasing.jar</p>
  </blockquote>

  <p>Unfortunately in some of the latest versions this file changed from .java to .jar.
  Is there a way to modify such files under Qt? Thxs...</p>
