Store record of purchased items locally vs query google play for purchased items [ queryInventoryAsync(QueryInventoryFinishedListener)]

I am using IAB for my application.

Google's IAB v3 API provides a method to query Google Play for managed items already owned by the user(device) v.i.z. queryInventoryAsync(QueryInventoryFinishedListener)

However, I also use a SQLite database for my app , so I am thinking of storing the record of purchased items in my own database instead of querying google play every second time.

Is this a bad idea?

What are the pros and cons of queryInventoryAsync vs storing purchased items in local SQLite database?

Solution

  • User can manually clear application data and your database will be dropped. Or user can run the application on another device with same account.

    Purchasing In-app Billing Products

    It is good practice to frequently query the In-app Billing service for the user’s purchases, for example whenever the app starts up or resumes, so that the user’s current in-app product ownership information is always reflected in your app.
