有没有Android的GCM相当于一个到了iOS推送通知反馈服务? [英] Is there an Android GCM equivalent to the iOS Push Notification Feedback Service?
问题描述
我们的web应用程序发送推送通知请求到iOS和Android设备。
有关的iOS,苹果推送通知服务有一个反馈服务,使您可以检测到哪些设备已经卸载你的应用程序,然后从数据库中删除它。
有没有为Android GCM了类似的反馈服务?如果不是,如何检测其Android用户不必再安装应用程序?
有没有为Android GCM了类似的反馈服务?
没有。
如果没有,如何检测其Android用户不必再安装应用程序?
引述文档:
- 在最终用户卸载应用程序。
- 的第三方服务器发送消息给GCM服务器。
- 的GCM服务器发送消息给设备。
- 的GCM客户端接收关于是否有广播接收器配置为接收它,它会返回错误信息和查询包管理器。
- 的GCM客户端通知应用程序卸载的GCM服务器。
- 的GCM服务器删除标记注册ID。
- 的第三方服务器发送消息给GCM。
- 的GCM返回NotRegistered错误信息给第三方服务器。
- 的第三方删除注册ID。
请注意,这可能需要一段时间的注册ID从GCM彻底清除。因此,有可能,在步骤7发送的邮件以上得到一个有效的消息ID作为响应,即使该消息将不会传递到设备。最终,注册ID将被删除,服务器将得到一个NotRegistered错误,没有任何进一步的行动从第三方服务器被要求(这种情况经常发生,而应用程序正在开发和测试)。
Our webapp sends push notification requests to iOS and Android devices.
For iOS, the Apple Push Notification Service has a feedback service so you can detect which devices have uninstalled your app and then remove it from your database.
Is there a similar feedback service for Android GCM? If not, how to detect which Android users no longer have the app installed?
Is there a similar feedback service for Android GCM?
No.
If not, how to detect which Android users no longer have the app installed?
Quoting the documentation:
- The end user uninstalls the application.
- The 3rd-party server sends a message to GCM server.
- The GCM server sends the message to the device.
- The GCM client receives the message and queries Package Manager about whether there are broadcast receivers configured to receive it, which returns false.
- The GCM client informs the GCM server that the application was uninstalled.
- The GCM server marks the registration ID for deletion.
- The 3rd-party server sends a message to GCM.
- The GCM returns a NotRegistered error message to the 3rd-party server.
- The 3rd-party deletes the registration ID.
Note that it might take a while for the registration ID be completely removed from GCM. Thus it is possible that messages sent during step 7 above gets a valid message ID as response, even though the message will not be delivered to the device. Eventually, the registration ID will be removed and the server will get a NotRegistered error, without any further action being required from the 3rd-party server (this scenario happens frequently while an application is being developed and tested).
