         * defined by {@link AssistStructure#getActivityComponent()}).

         * <p><b>Warning:</b> an autofill service cannot trust the value reported by this method

         * without verifing its authenticity—see the "Web security" section of

         * {@link android.service.autofill.AutofillService} for more details.
