帮帮我！！！
我是安卓系统的初学者，目前正在做一个测试应用程序。这个应用程序只有2个按钮，当你按下"购买测试项目"按钮时，它会进行应用内购买。当你按下使用按钮时，它会运行consumerPurchase功能。
这是我的代码：

我的开发者控制台上有应用内产品，我在清单文件中授予权限。
第一次，它运行得很好，但当我试图通过按下"使用按钮"删除购买并再次运行它时，它给了我"错误，你已经拥有这个项目"的消息。
有人能给我一个解决这个问题的办法吗？
您遇到这个问题是因为产品没有被消费。因为你只能在消费后的另一个时间购买产品。
请检查您的消费按钮代码。
此外，我建议您使用最新的inAppBilling API的
