     * @param admin Which {@link DeviceAdminReceiver} this request is associated with.

     * @param timeoutMs The new timeout, after which the user will have to unlock with strong

     *         controlling the timeout.

     *         72 hours, respectively. Though discouraged, the admin may choose to require strong
