After a long search for an answer, I want to ask a very simple question here. Are transactions associated with a auto-renewable subscription removed after the expiration date from the list of transactions that can be obtained using the restoreCompletedTransactions() method?
In its simplest implementation, is it possible to manage application content associated with a auto-renewable subscription without using Validating Receipts? And using only the result of the restoreCompletedTransactions() method?
You have two questions here.
1) Are transactions associated with a auto-renewable subscription removed after the expiration date from the list of transactions that can be obtained using the restoreCompletedTransactions() method?
Answer: No. Those entries will always remain there and when you validate the receipt, you will get it back in response. By Doing the Restore purchase won't delete the existing entries from receipt. When you testing the In app purchase with Sandbox account then you will have 35 mins to use that account within 8 Hours. You can do whatever you want. You can do subscription again(In this case system will say us that your subscription is still running). After 35 mins of first purchased, Plan will be considered as Cancel and you need to do Subscription again(Only in Sandbox mode, Well In production mode May be it will not ask to do subscription again? I am not sure here.)
2) Is it possible to manage application content associated with a auto-renewable subscription without using Validating Receipts
Answer: No. Its good to use the receipt validation for locking/unlocking content of your application.
