UserManager

public class UserManager
extends Object

java.lang.Object
   ↳ android.os.UserManager

Manages users and user details on a multi-user system. There are two major categories of users: fully customizable users with their own login, and profiles that share a workspace with a related user.

Users are different from accounts, which are managed by AccountManager. Each user can have their own set of accounts.

See DevicePolicyManager#ACTION_PROVISION_MANAGED_PROFILE for more on managed profiles.

    DISALLOW_REMOVE_MANAGED_PROFILE

    public static final String DISALLOW_REMOVE_MANAGED_PROFILE

    This constant is deprecated.
    As the ability to have a managed profile on a fully-managed device has been removed from the platform, this restriction will be silently ignored when applied by the device owner. When the device is provisioned with a managed profile on an organization-owned device, the managed profile could not be removed anyway.

    Specifies whether the user can share file / picture / data from the primary user into the managed profile, either by sending them from the primary side, or by picking up data within an app in the managed profile.

    When a managed profile is created, the system allows the user to send data from the primary side to the profile by setting up certain default cross profile intent filters. If this is undesired, this restriction can be set to disallow it. Note that this restriction will not block any sharing allowed by explicit DevicePolicyManager#addCrossProfileIntentFilter calls by the profile owner.

    This restriction is only meaningful when set by profile owner. When it is set by device owner, it does not have any effect.

    The default value is false.

    Constant Value: "no_sharing_into_profile"

    DISALLOW_SHARE_LOCATION

    public static final String DISALLOW_SHARE_LOCATION

    Specifies if a user is disallowed from turning on location sharing.

    In a managed profile, location sharing by default reflects the primary user's setting, but can be overridden and forced off by setting this restriction to true in the managed profile.

    A device owner and a profile owner can set this restriction. When it is set by a device owner, a profile owner on the primary user or by a profile owner of an organization-owned managed profile on the parent profile, it prevents the primary user from turning on location sharing.

A feedback report isn't collected as there is no way for the user to provide explicit consent. The default value is false.

    When this user restriction is set by device owners, it's applied to all users. When set by the profile owner of the primary user or a secondary user, the restriction affects only the calling user. This user restriction has no effect on managed profiles.

    Key for user restrictions.

    Type: Boolean

    DISALLOW_UNIFIED_PASSWORD

    public static final String DISALLOW_UNIFIED_PASSWORD

    Specifies that the managed profile is not allowed to have unified lock screen challenge with the primary user.

    This restriction can only be set by a device owner, a profile owner on the primary user or a profile owner of an organization-owned managed profile on the parent profile. When it is set by a device owner, it applies globally. When it is set by a profile owner on the primary user or by a profile owner of an organization-owned managed profile on the parent profile, it disables the primary user from transferring files over USB. No other user on the device is able to use file transfer over USB because the UI for file transfer is always associated with the primary user.

    Returns an intent to create a user for the provided name and account name. The name and account name will be used when the setup process for the new user is started.

    The intent should be launched using startActivityForResult and the return result will indicate if the user consented to adding a new user and if the operation succeeded. Any errors in creating the user will be returned in the result code. If the user cancels the request, the return result will be Activity#RESULT_CANCELED. On success, the result code will be Activity#RESULT_OK.

    Parameters
    userName String: Optional name to assign to the user. This value may be null.
    accountName String: Optional account name that will be used by the setup wizard to initialize the user. This value may be null.
    accountType String: Optional account type for the account to be created. This is required if the account name is specified. This value may be null.

    public boolean isUserUnlocked (UserHandle user)

    Return whether the given user is running in an "unlocked" state.

    On devices with direct boot, a user is unlocked only after they've entered their credentials (such as a lock pattern or PIN). On devices without direct boot, a user is unlocked as soon as it starts.

    When a user is locked, only device-protected data storage is available. When a user is unlocked, both device-protected and credential-protected private app data storage is available.

    Requires android.permission.MANAGE_USERS or android.permission.INTERACT_ACROSS_USERS, otherwise specified user must be the calling user or a profile associated with it.

    Parameters
    user UserHandle: to retrieve the unlocked state for.
    Returns
    boolean

    requestQuietModeEnabled

    public boolean requestQuietModeEnabled (boolean enableQuietMode, 
                UserHandle userHandle, 
                int flags)

    Perform the same operation as requestQuietModeEnabled(boolean, android.os.UserHandle), but with a flag to tweak the behavior of the request.

    Parameters
    enableQuietMode boolean: whether quiet mode should be enabled or disabled
    userHandle UserHandle: user handle of the profile This value cannot be null.
    flags int: Can be 0 or QUIET_MODE_DISABLE_ONLY_IF_CREDENTIAL_NOT_REQUIRED. Value is either 0 or a combination of QUIET_MODE_DISABLE_ONLY_IF_CREDENTIAL_NOT_REQUIRED, and android.os.UserManager.QUIET_MODE_DISABLE_DONT_ASK_CREDENTIAL
    Returns
    boolean false if user's credential is needed in order to turn off quiet mode, true otherwise
    Throws
    SecurityException if the caller is invalid
    IllegalArgumentException if userHandle is not a managed profile

    See also:

    requestQuietModeEnabled

    public boolean requestQuietModeEnabled (boolean enableQuietMode, 
                UserHandle userHandle)

    Enables or disables quiet mode for a managed profile. If quiet mode is enabled, apps in a managed profile don't run, generate notifications, or consume data or battery.

    If a user's credential is needed to turn off quiet mode, a confirm credential screen will be shown to the user.

    The change may not happen instantly, however apps can listen for Intent#ACTION_MANAGED_PROFILE_AVAILABLE and Intent#ACTION_MANAGED_PROFILE_UNAVAILABLE broadcasts in order to be notified of the change of the quiet mode. Apps can also check the current state of quiet mode by calling isQuietModeEnabled(android.os.UserHandle).

    The caller must either be the foreground default launcher or have one of these permissions: MANAGE_USERS or MODIFY_QUIET_MODE.

    Parameters
    enableQuietMode boolean: whether quiet mode should be enabled or disabled
    userHandle UserHandle: user handle of the profile This value cannot be null.
    Returns
    boolean false if user's credential is needed in order to turn off quiet mode, true otherwise
    Throws
    SecurityException if the caller is invalid
    IllegalArgumentException if userHandle is not a managed profile
