title: How to Verify Subscriptions - Google Subscription
body: <p>I am using google purchase library 4.0. When customers want to start a subscription, they press the Buy button and make a purchase. If he closes the app or loses internet connection right after the purchase is complete, his payment cannot be verified. (onPurchasesUpdated) How can we prevent this? When I go to the Google Subscriptions page, it says Open App, but running the application is not enough to verify the payment. After a while, the user is automatically refunded. How can we prevent this?
  I shared the github project made by google below. I am working on this project.</p>
