I have tried for several days to solve this problem, using the Dungeons demo code that comes with the SDK. I\'ve tried to Google for an answer but can\'t find one.
Yes, the problem still occurs. After I bought android.test.purchased I start getting the error on quering the inventory. It is possible to fix your phone by just clearing data of Google Play Store application and running Google Play one time. When you clear data of Google Play it forgets that you bought android.test.purchased
