Testing in-app billing: “The publisher cannot purchase this item”

Question

My app seems ready to get a \'real life\' test for an in-app purchase procedure on my device. However, I receive an \"The publisher cannot purchase this item\" error message in

Answer 1

Summarizing my own pitfalls:

• upload your app in alpha or beta channel
• publish your app(publishing in beta or alpha channels didn't make your app visible to anyone except those in testers list)
• add your account to the "testers" list
• go to "testers" link (something like "https://play.google.com/apps/testing/< package_name>") and click "participate" (That's one that I missed)
• publish your inapp items
• build release(!) version of the app and upload it onto device.

• make sure that device version and market version are signed by the same release key

• make sure that market version number is not smaller than one defined in the build gradle
