This tool converts carrier config and APNs from XML format to protobuf format.

AOSP default carrier configs can be found in packages/apps/CarrierConfig, and APNs in device/sample/etc/apns-full-conf.xml.

Usage:

$ source build/envsetup.sh $ lunch foo_bar $ croot $ source /main.sh

The commands above build the tool from source code and run them.

This tool is best supported on Android 11 code base. See additional steps in bin/README.md run it on Android 10.

Usually, if a MVNO has no APN defined in xml, the tool will use APNs of the corresponding MNO, based on MCC/MNC values. However, a CarrierConfig carriersettingstool.no_apn_for_mvno_bool can be set as true to avoid such copying in conversion tool. carriersettingstool.no_apn_for_mvno_bool will also be removed from final config by the tool.
