我正在抓狂！上星期某个时候，这还能用。
我正在尝试为Android应用添加应用内购买功能。我按照TrivialDrive的示例进行操作，我的代码有时可以正常工作。但现在它不行了。
我正在创建一个简单的问答游戏，其中包含一些免费问题以及升级以获取更多问题的选项。当用户完成免费问题列表时，他们将被带到“游戏结束”屏幕，在该屏幕上，他们可以擦除答案并重新开始或升级。
当我点击“升级”按钮时，我可以进行成功的购买，但是一旦Google的“付款成功”对话框消失后，我的活动就被销毁，然后我被送回到主活动。
当我尝试返回并再次进行购买时，我的代码捕获错误（“您已拥有此项目”），并适当地处理它。我的代码向用户解释他们已经拥有升级，并允许他们点击一个按钮继续玩。因此，看起来OnIabPurchaseFinishedListener此时正在触发。
我使用最新的Google助手代码更新了代码文件。
非常感谢任何帮助或建议，以便寻找答案。
谢谢。
