isSuperUser

public static boolean isSuperUser(User user)

参数:

user - to check

返回:

true if current user is a super user (whether as user running process, declared as individual superuser or member of supergroup), false otherwise.

抛出:

IllegalStateException - if lists of superusers/super groups haven't been initialized properly

isSuperUser

@Deprecated
public static boolean isSuperUser(String user)

已过时。 this method is for backward compatibility, use isSuperUser(User) instead

参数:

user - to check

返回:

true if current user is a super user (whether as user running process, or declared as superuser in configuration), false otherwise.
