What I have accomplished :
(我完成了什么:)
Google Play billing works and I am able to purchase a subscription successfully.
(Google Play结算有效,我可以成功购买订阅。)
What I want :
(我想要的是 :)
Now I want to add a notification feature every time the state of the subscription changes (ie. Renewal, Cancellation, etc.) Since subscriptions auto renews, I would like to notify the user every time it happens.
(现在,我想在每次订阅状态更改时(例如,续订,取消等)添加通知功能。由于订阅会自动续订,因此我想在每次发生时通知用户。)
My problem :
(我的问题 :)
I know how to make a simple notification, but my problem is when.
(我知道如何发出简单通知,但是我的问题是何时。)
How do I retrieve when the subscription starts (or renewal date), when it ends (or next renewal date). (如何检索订阅何时开始(或续订日期),订阅何时结束(或下一个续订日期)。)
And how do I send the notification? (以及如何发送通知?)
Do I start a background service? (我要启动后台服务吗?)
I do not have a back end to implement the Google Cloud Pub/Sub (我没有后端来实现Google Cloud Pub / Sub)
