How to know if the android device supports multi users?

Android 4.2 supports multiple user spaces "on shareable devices such as tablets"(http://developer.android.com/about/versions/android-4.2.html#MultipleUsers). How do I know if a specific device is a "shareable device"?

Can I programmatically check if the device supports multiple users?

If it is enough for you to check if multiple users accounts have been created on the device, you can use UserManager.getUserCount() (after ensuring the SDK version is > 16).

I don't know if it's possible to distinguish if multiple users are theoretically possible, but only one has been used so far from no multi-user support at all.

EDIT: This solution does actually not work, it seems it requires a system-level permission. See here for details UserManager getUserCount() (Jelly Bean)

There is a hidden API at UserManager.supportsMultipleUsers(). You can access this using the following method which uses reflection, though this technique is not normally recommended because the API could change in a later release.

public static boolean supportsMultipleUsers() {
  try {
  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
     // return UserManager.supportsMultipleUsers();
     return (Boolean(UserManager.class.getDeclaredMethod("supportsMultipleUsers").invoke(null));
  }
  catch (Exception e) {}
  return false;
}

You can check the Android version with the following code:

int oSversion = Integer.valueOf(android.os.Build.VERSION.SDK_INT);

if (osVersion > 16) {
   // This phone supports multi-user   
}
