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

  <p>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.</p>

  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. </p>
  
  <p>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?</p>
