Common issues​

Most of the issues encountered by users are caused by:

  • A device simulator. Use a real device for testing!
  • An incorrect usage of the library. Read the documentation.
  • For Android, a hold in your payment profile on Google Play Console. Check for any warnings.

getProducts returns an empty array​

  • Please double check if you've called initConnection.
  • Please wait for max. 24 hours to fetch your IAP products if you've just uploaded them. Related to issue.
  • For iOS, from iOS version >=13, we seem to use StoreKit to fix this issue as mentioned in stackoverflow.
  • For android, please double check issue comment here and see if you've missed something.

getAvailablePurchases() returns an empty array​

  • getAvailablePurchases() is used only when you purchase a non-consumable product. This can be restored only.
  • If you want to find out if a user subscribes the product, you should check the receipt which you should store in your own database.
  • Apple suggests you handle this in your own backend to do things like what you are trying to achieve.
