I have created an application in which there is in-app purchases which has monthly auto renewal.. on first time successful payment i have called a web-service in which i have made the user to premium class.
Now if the user has cancelled the payment manually from the google server, how could i know that user has cancelled his/her subscription.
Is there is some PHP code query or from android i have to called something in background to check the status??
Thank you in advace
You can check the purchased subscriptions inside the app via
Edit: For subscriptions use "subs", for inapp-purchases use "inapp" e.g.:
Inapp-Purchases: mService.getPurchases(3, getPackageName(), "inapp", null);
Subscriptions: mService.getPurchases(3, getPackageName(), "subs", null);
See also Querying for Purchased Items at http://developer.android.com/google/play/billing/billing_integrate.html
So you can implement a task in your app where you check if the user still has a subscription. If not, you can remove the premium status. Moreover this information could be useful for you:
When the user cancels a subscription, Google Play does not offer a refund for the current billing cycle. Instead, it allows the user to have access to the canceled subscription until the end of the current billing cycle, at which time it terminates the subscription. For example, if a user purchases a monthly subscription and cancels it on the 15th day of the cycle, Google Play will consider the subscription valid until the end of the 30th day (or other day, depending on the month).

Hope this could help you
Edit2: Because the AIDL library which is mentioned in my answer is deprecated and deactivated in the future, it is recommended to switch to the new Google Play Billing Library.
