Android: in-app billing issue

I integrate billing in the application in my application. But I have problems testing my application. Every time I try to purchase an application element. A wired message appears The item you tried to buy was not found . The following appeared on Logcat:

09-10 14:45:02.437: E/IabHelper(12617): Launching buy intent for premium. Request code: 10001 09-10 14:45:02.523: E/Finsky(11260): [8464] FileBasedKeyValueStore.delete: Attempt to delete 'paramspXaplU_vTGhfGqvnmPPddQ' failed! 09-10 14:45:04.000: E/Volley(11260): [8448] BasicNetwork.performRequest: Unexpected response code 500 for https://android.clients.google.com/fdfe/preparePurchase

After I click OK, logcat showed the following:

 09-10 14:45:05.546: E/TrivialDrive(12617): onActivityResult(10001,0,Intent { (has extras) } 09-10 14:45:05.546: E/IabHelper(12617): Ending async operation: launchPurchaseFlow 09-10 14:45:05.546: E/IabHelper(12617): Purchase canceled - Response: 2:Unknown 09-10 14:45:05.546: E/TrivialDrive(12617): Purchase finished: IabResult: User canceled. (response: -1005:User cancelled), purchase: null 09-10 14:45:05.546: E/TrivialDrive(12617): **** TrivialDrive Error: Error purchasing: IabResult: User canceled. (response: -1005:User cancelled)

I have checked the following things many times:

  • I am logged in with the same google account on my test device that I set up as a test account.
  • All In-app applications I created are active.
  • I uploaded apk to alpha channel, it is mentioned that draft mode is no longer supported .
  • I checked the license key for my application from the developer console.
  • Someone suggested restarting my device once. I did it too.
  • I installed on my device the same apk that was downloaded on Google Play. Both sign with the same certificate.
  • It is mentioned that you should expect at least 2-3 hours to get apk recognition. For me it was more than 15 hours.
  • In addition, my test account is different from the seller account.

I changed the Google pattern and also created my own pattern. In both cases, I faced the same problem.

Update: I am testing IAB from my client account. I noticed that her wallet trading account is still not verified. I am not sure if this is the main cause of this problem.

The reason for this problem was pretty dumb, after downloading the application to the alpha channel, you need to publish it. I did not publish it, so it remained in draft mode. After I published the application, it worked for an hour.

This may help someone: make sure your test application does not have a higher version code defined by the one you downloaded in the play store.
