title: When do android app get the "Expired" status after canceling the subscription during the trial period
body: <p>There is a "Subscription with Free Trial" in my android app, and the BillingService would get the Purchased status after buying subscription product.</p>
  
  <p>But, the BillingService does not get the Expired status after canceling the subscription.</p>
  
  <p>However, accroding to <a href="http://developer.android.com/intl/zh-TW/google/play/billing/v2/billing_subscriptions.html#trials" rel="noreferrer">Android Developer</a>,</p>
  
  <blockquote>
    <p>"If necessary, the user can cancel the subscription at any time during
    the trial period. In this case, Google Play marks the subscription as
    expired immediately, rather than waiting until the end of the trial
    period."</p>
  </blockquote>
  
  <p>but My app does not get the status.</p>
  
  <p>I wonder that When does android app get the "Expired" status after canceling the subscription during the trial period.</p>
