         [1,7,0] for TYPE_WIFI, TYPE_BLUETOOTH, and TYPE_MOBILE.

         This list is also modified by code within the framework, including:

             - TYPE_ETHERNET (9) is prepended to this list, and

             - the return value of TelephonyManager.isTetheringApnRequired()
               determines how the array is further modified:

                   * TRUE (DUN REQUIRED).
                     TYPE_MOBILE is removed (if present).
                     TYPE_MOBILE_HIPRI is removed (if present).
                     TYPE_MOBILE_DUN is appended (if not already present).

                   * FALSE (DUN NOT REQUIRED).
                     TYPE_MOBILE_DUN is removed (if present).
                     If both of TYPE_MOBILE{,_HIPRI} are not present:
                        TYPE_MOBILE is appended.
                        TYPE_MOBILE_HIPRI is appended.
