Here what does "user" mean?这里的“用户”是什么意思?
unique to each combination of app-signing key, user, and device https://developer.android.com/reference/android/provider/Settings.Secure#ANDROID_ID .应用签名密钥、用户和设备https://developer.android.com/reference/android/provider/Settings.Secure#ANDROID_ID的每个组合都是唯一的。
Later in the same docs :稍后在同一个文档中:
On devices that have multiple users , each user appears as a completely separate device, so the
ANDROID_ID
value is unique to each user.在有多个用户的设备上,每个用户都显示为一个完全独立的设备,因此
ANDROID_ID
值对每个用户都是唯一的。
And following the link there:并按照那里的链接:
Android now allows multiple user spaces on shareable devices such as tablets.
Android 现在允许在平板电脑等可共享设备上使用多个用户空间。 Each user on a device has their own set of accounts, apps, system settings, files, and any other user-associated data
设备上的每个用户都有自己的一组帐户、应用程序、系统设置、文件和任何其他与用户相关的数据
