In-App Billing test: android.test.purchased already owned
问题 I am currently testing In-App Billing for a future app, and after I successfully "bought" the test item "android.test.purchased" the first time, I now receive the response code 7 every time I try to buy it again, which means that I already own this item. 12-15 23:02:14.149: E/IabHelper(19829): In-app billing error: Unable to buy item, Error response: 7:Item Already Owned From what I understand, this purchase is supposed to always be possible, right? So that the developer can test his/her app?
