As a developer, encountering the error message "The item you requested is not available for purchase" can disrupt the user experience and affect your app’s revenue. In this article, we will explore the various causes of this error and provide a detailed guide on how to troubleshoot and resolve it
One of the most common errors you might encounter implementing Google Play Billing is BillingResponseCode.ITEM_UNAVAILABLE (code 4). The corresponding message from the BillingClient API is frustratingly vague. Here's how to fix it.
Fixing "The Item You Requested is Not Available for Purchase" error
1 Add Your App to a Test Track
Ensure your app has been uploaded to the Google Play Console at least once and assigned to a test track (internal, alpha, or beta).
2. Activate Your Products
Confirm that the in-app purchase or subscription product is active and properly configured in the Play Console. Inactive products cannot be bought.
3. Add Testers to Test Track
Add approved testers to your internal, alpha, or beta test tracks. These testers must also join the test via the provided link in the Play Console.
4. Enable License Testing
Under Setup > License Testing, add the Google accounts of your testers. This allows them to make test purchases using test credit cards, avoiding actual charges.
5. Verify Google Play Account
Ensure the Google Play account signed in on the testing device matches the one added for testing and license testing. This account must be the active account before attempting any test purchases.
