问题描述

我希望能够得到用户购买的状态，但当前应用程序他们是从当它被支付给释放。

I want to be able to get the state of the user purchases but on the current app they are in from when it was paid to free.

例如应用超级跑车支付应用程序，但最新的更新使得自由搭配应用内购买。我想谁的应用程序能够访问付费内容，但新用户支付previous用户没有访问中，他们将需要支付。

推荐答案

环顾四周，接触特定的人之后，我发现它不是由谷歌的支持，我很失望，在为谷歌的开发Play中的应用，大量的功能仍下落不明。

After looking around and contacting certain people I've found out that it's not supported by Google, I'm disappointed at the developing Apps for Google Play, lots of features still missing.
