我关注了 Google GCM Google Cloud Messaging for Android。但它向所有设备而不是特定设备运行通知。如何向特定设备发送通知。
我相信我需要注册 ID。但是注册ID的定义是:
An ID issued by the GCM servers to the Android application that allows it to receive
messages. Once the Android application has the registration ID, it sends it to the
3rd-party application server, which uses it to identify each device that has registered
to receive messages for a given Android application. In other words, a registration ID
is tied to a particular Android application running on a particular device.
这里是什么意思 3rd 方应用程序。
请指导我。任何帮助将不胜感激。
