            Each item should have two elements and be separated with ";".

            The first element is downstream types which is one of tethering. This element has to be
            made by WIFI, USB, BT, and OR'd with the others. Use "|" to combine multiple downstream
            types and use "," to separate each combinations. Such as

            USB|BT,WIFI|USB|BT

            The second element is icon for the item. This element has to be composed by
            <package name>:drawable/<resource name>. Such as

            1. com.android.networkstack.tethering:drawable/stat_sys_tether_general
            2. android:drawable/xxx

            So the entire string of each item would be

            USB|BT,WIFI|USB|BT;com.android.networkstack.tethering:drawable/stat_sys_tether_general

            NOTE: One config can be separated into two or more for readability. Such as

                  WIFI|USB,WIFI|BT,USB|BT,WIFI|USB|BT;android:drawable/xxx

                  can be separated into

                  WIFI|USB;android:drawable/xxx
                  WIFI|BT;android:drawable/xxx
                  USB|BT;android:drawable/xxx
                  WIFI|USB|BT;android:drawable/xxx

            Notification will not show if the downstream type isn't listed in array.
            Empty array means disable notifications. -->
