C2DM中的设备ID

Question

据我所知，C2DM是每个设备每个设备的事物。.但是我的问题是，设备ID的用途是什么？在C2DM中我们在哪里使用设备ID？

Answer 1

Device Id term is used in iPhone and Registration ID is the term which we use in Android.

Registration ID

An ID issued by the C2DM servers to the Android application that allows it to receive messages. Once the application has the registration ID, it sends it to the third-party application server, which uses it to identify each device that has registered to receive messages for a given application. In other words, a registration ID is tied to a particular application running on a particular device.

Answer 2

The device ID is afaik your Google Account

See "Sender ID"

An email account associated with the application's developer. The sender ID is used in the registration process to identify a Android application that is permitted to send messages to the device. This ID is typically role-based rather than being a personal account—- for example, my-app@gmail.com.
