Android Play Billing Library: onSkuDetailsResponse responseCode is 0, but the size of skuDetailsList is also 0

I have spent few hours with this issue and the problem was that my debug build/CI builds had applicationIdSuffix. So only production build with proper applicationId was able to retrieve the products.

Sounds like you're having issues with your Google Play Console setup.

Please check that:

• your app is published in Play Console (to PROD or your @gmail account is in the user's alpha/beta group)
  • I also recommend adding your test @gmail account into license testers list to avoid being charged and license issues
• has correct signature and version code of test app is equal to published one
• all of your SKUs are also published
• your Play Store app works correctly on the phone you're testing (allows you to purchase apps for example)

And wait for some time after setup is done.

I also had the same problem, but by doing the following, I got SkuDetails.

• Stop Google Play app
• Delete cache of Google Play app
• Stop the application and start it
