1This tool converts carrier config and APNs from XML format to protobuf format. 2 3AOSP default carrier configs can be found in packages/apps/CarrierConfig, 4and APNs in device/sample/etc/apns-full-conf.xml. 5 6Usage: 7 8$ source build/envsetup.sh 9$ lunch foo_bar 10$ croot 11$ source <path>/main.sh 12 13The commands above build the tool from source code and run them. 14 15This tool is best supported on Android 11 code base. See additional steps 16in bin/README.md run it on Android 10. 17 18Usually, if a MVNO has no APN defined in xml, the tool will use APNs of the corresponding MNO, 19based on MCC/MNC values. However, a CarrierConfig carriersettingstool.no_apn_for_mvno_bool 20can be set as true to avoid such copying in conversion tool. 21carriersettingstool.no_apn_for_mvno_bool will also be removed from final config by the tool. 22
