* {@link #EXTRA_PROVISIONING_DEVICE_ADMIN_COMPONENT_NAME} instead, although specifying only
* {@link #EXTRA_PROVISIONING_DEVICE_ADMIN_PACKAGE_NAME} is still supported.
*
* <p> When managed provisioning has completed, broadcasts are sent to the application specified
* in the provisioning intent. The
* {@link DeviceAdminReceiver#ACTION_PROFILE_PROVISIONING_COMPLETE} broadcast is sent in the
* managed profile and the {@link #ACTION_MANAGED_PROFILE_PROVISIONED} broadcast is sent in
* the primary profile.
*
* <p> If provisioning fails, the managedProfile is removed so the device returns to its
* previous state.
