* Provisioning adds a managed profile and sets the MDM as the profile owner who has full

* {@link #EXTRA_PROVISIONING_DEVICE_ADMIN_COMPONENT_NAME} instead, although specifying only
* {@link #EXTRA_PROVISIONING_DEVICE_ADMIN_PACKAGE_NAME} is still supported.
*
* <p>The intent may also contain the following extras:
* <ul>
* <li>{@link #EXTRA_PROVISIONING_ACCOUNT_TO_MIGRATE}, optional </li>

*
* <p>When managed provisioning has completed, broadcasts are sent to the application specified
* in the provisioning intent. The

* managed profile and the {@link #ACTION_MANAGED_PROFILE_PROVISIONED} broadcast is sent in

* {@link #ACTION_PROVISIONING_SUCCESSFUL} will also be sent to the profile owner.

* previous state.
*
* <p>If launched with {@link android.app.Activity#startActivityForResult(Intent, int)} a
