GCMRegistrar.register(this.context, CommonUtilities.SENDER_ID);

我不知道什么是两个ID？

I don't know what is the difference between two ids?

推荐答案

这两个是完全不同的。

Both are completely different.

Secure.ANDROID_ID

一个64位数字（作为一个十六进制字符串）是随机的产生   设备的首次启动，并应保持不变的寿命   设备。 （如果在执行出厂重置价值可能会改变   装置。）

A 64-bit number (as a hex string) that is randomly generated on the device's first boot and should remain constant for the lifetime of the device. (The value may change if a factory reset is performed on the device.)

和 GCMRegistrar.register（this.context，CommonUtilities.SENDER_ID）; 为您提供了设备的registartion ID从的 GCM 。通过它，GCM唯一标识设备。

And GCMRegistrar.register(this.context, CommonUtilities.SENDER_ID); Gives you the registartion id of device from GCM. By which, GCM uniquely identifies the device.

另一个区别是 Secure.ANDROID_ID 可能改变当设备上进行恢复出厂设置。和登记ID定期得到改变。

Another difference is Secure.ANDROID_ID may change when factory reset is performed on the device. And Registration id gets changes periodically.

如果你是问有关 CommonUtilities.SENDER_ID 随后的此是项目数，它将被用于以后的GCM发件人ID 的

And if you are asking about CommonUtilities.SENDER_ID then This is your project number, and it will be used later on as the GCM sender ID
