一个GCM注册ID是唯一到Android登录&设备。如果用户使用相同的登录名登录2台设备，则它们将具有不同的GCM ID。从这个link

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.
