                                        e.printStackTrace();
                                    }

这背后的想法是，我有月订阅我想要检索，如果他订阅或不订阅。如果他订阅了我将共享优先付为1，如果不是“”。

这样做吗？如果我现在购买，我能做到正确吗？如果我取消订阅怎么办？我是否已经列入名单？

Answer 1

关于this手册，您可以检测用户是否使用订阅 getBuyIntent()。

它产生purchaseState = 0。

我只建议每次用户启动应用时检测状态。您可以在developerPayload中手动设置订阅的时间长度。我建议不要使用共享偏好。或使用encription保护您的数据，以保护您的应用。
