When multiple users on android, is the ANDROID_ID unique for each user?

Question

http://developer.android.com/reference/android/provider/Settings.Secure.html#ANDROID_ID

This link says that : When a device has multiple users (available on certain devices running Android 4.2 or higher), each user appears as a completely separate device, so the ANDROID_ID value is unique to each user.

http://developer.android.com/about/versions/android-4.2.html#MultipleUsers While this link says: Beware that if your app requests one of the hardware device identifiers (such as the WiFi MAC address, the SERIAL number, or the ANDROID_ID number), they will provide the same value for each user because these identifiers are tied to the hardware and not the user.

Both are from android developer and have got me confused? Is the ANDROID_ID actually unique or not for multiple users on a single device?

Answer 1

这里有一个问题。

这似乎是文档中的错误，因此 ANDROID_ID 对于单个设备上的多个用户应该是不同的。

最好的办法是测试一下自己，如果您有 4.2 平板电脑，但其他一些人已经在这里测试过它，并且它似乎运行良好。
