Android – 如何检查订阅是否续订？

我有一个可更新的每月订阅的Android应用程序.在这个应用程序中,我想在下个月他的订阅继续时通知用户一些信息.

正如我可以看到商家中心的续订(orderId以例如.0,..1结尾),但在查询库存时,我的采购订单ID与efor eq相同.

{
    "orderId": "GPA.XXXX-YYYY-XXXX-ZZZZZ",
    "packageName": "my.packageName",
    "productId": "my.sku",
    "purchaseTime": 1456398623654,
    "purchaseState": 0,
    "developerPayload": "mypayload",
    "purchaseToken": "token",
    "autoRenewing": true
}

令我困扰的是,buyTime也没有改变.

所以我的问题是：如果有任何方法可以在应用程序中检测到更新发生了吗？

编辑：

我正在使用Google Play Developer API获取订阅信息,然后自行计算续订数量.

解决方法:

所有重复的订单ID在INAPP_PURCHASE_DATA JSON字段的orderId字段中返回(在V3中),每个重复的事务都附加一个整数.

Subscription order numbers

To help you track transactions relating to a given subscription,
Google payments provides a base Merchant Order Number for all
recurrences of the subscription and denotes each recurring transaction
by appending an integer as follows:

GPA.1234-5678-9012-34567 (base order number)
GPA.1234-5678-9012-34567..0 (first recurrence orderID)
GPA.1234-5678-9012-34567..1 (second recurrence orderID)
GPA.1234-5678-9012-34567..2 (third recurrence orderID) ...

但由于local caching,您可能无法获得最新信息.因此,请尝试从应用程序管理器清除缓存,先查看是否获得了正确的购买信息

由于购买查询这种方式不可靠,因此从后端调用Google Play Developer Purchases.subscriptions: get API获取Purchases.subscriptions resource会更有意义,这将返回当前订阅的expiryTimeMillis.

{
  "kind": "androidpublisher#subscriptionPurchase",
  "startTimeMillis": long,
  "expiryTimeMillis": long,
  "autoRenewing": boolean,
  "priceCurrencyCode": string,
  "priceAmountMicros": long,
  "countryCode": string,
  "developerPayload": string,
  "paymentState": integer,
  "cancelReason": integer
}
