DevicePolicyManager.ACTION_SET_NEW_PASSWORD intent and show an interface
to configure a separate lock screen credential for the managed profile.
The lock screen credentials of the managed profile MUST use the same
credential storage and management mechanisms as the parent profile, as
documented on the Android Open Source Project Site .
The DPC password policies MUST apply to only the managed profile's lock
screen credentials unless called upon the DevicePolicyManager instance returned
by getParentProfileInstance .
When contacts from the managed profile are displayed in the preinstalled call log, in-call
UI, in-progress and missed-call notifications, contacts and messaging apps they SHOULD
be badged with the same badge used to indicate managed profile applications.
3.9.3 Managed User Support
If device implementations declare android.software.managed_users , they:
[C-1-1] MUST provide a user affordance to logout from the current user and switch back
to the primary user in multiple-user session when isLogoutEnabled returns true . The user
affordance MUST be accessible from the lockscreen without unlocking the device.
3.10. Accessibility
Android provides an accessibility layer that helps users with disabilities to navigate their devices
more easily. In addition, Android provides platform APIs that enable accessibility service
implementations to receive callbacks for user and system events and generate alternate feedback
mechanisms, such as text-to-speech, haptic feedback, and trackball/d-pad navigation.
If device implementations support third-party accessibility services, they:
[C-1-1] MUST provide an implementation of the Android accessibility framework as
described in the accessibility APIs SDK documentation.
[C-1-2] MUST generate accessibility events and deliver the appropriate AccessibilityEvent to
all registered AccessibilityService implementations as documented in the SDK.
[C-1-3] MUST honor the android.settings.ACCESSIBILITY_SETTINGS intent to provide a user-
accessible mechanism to enable and disable the third-party accessibility services
alongside the preloaded accessibility services.
[C-1-4] MUST add a button in the system's navigation bar allowing the user to control the
accessibility service when the enabled accessibility services declare the
AccessibilityServiceInfo.FLAG_REQUEST_ACCESSIBILITY_BUTTON . Note that for device
implementations with no system navigation bar, this requirement is not applicable, but
device implementations SHOULD provide a user affordance to control these accessibility
services.
If device implementations include preloaded accessibility services, they:
[C-2-1] MUST implement these preloaded accessibility services as Direct Boot Aware
apps when the data storage is encrypted with File Based Encryption (FBE).
SHOULD provide a mechanism in the out-of-box setup flow for users to enable relevant
accessibility services, as well as options to adjust the font size, display size and
magnification gestures.
