我试图弄清楚整个 Android 许可问题,并感到沮丧。在模拟器中,我运行没有帐户或不在测试环境中的应用程序,它似乎工作正常,返回未获得许可的响应并弹出立即购买应用程序消息。
当我尝试在实际的 Android 设备上运行它时,它每次都会返回许可,即使设备帐户不是在测试环境中的帐户。此外,即使它返回许可,“检查许可”框也永远不会消失,除非您单击取消。然后它只允许您使用该应用程序,就好像它已获得许可一样。它主要是示例中的 C&P,有一些更改。我删除了检查许可证按钮和状态文本框。

我只是不知道我需要更改什么才能使其工作......或者许可证是否以某种方式被缓存(即使这是我第一次在此设备上运行它)以及我是否可以在不擦除的情况下取消缓存它该设备,因为当我在其他应用程序上进行测试时,这会很好。另外,如何在不单击取消按钮的情况下删除“检查许可证”消息……我应该让它不显示吗?
