====== carrier_list.textpb ======

DO NOT MANUALLY EDIT THIS FILE

This file is the textpb verion of carrier_list.pb files under assets/, for readability purpose only.

This file is not build into pb, thus modification of this file won't take any effect.

===== carrier_list.pb =====
DO NOT MANUALLY EDIT THIS FILE

This file defines carrier id and should be single versioned.

===== How to test carrier id locally =====

If you want to make change locally during testing, currently there are two ways:

1. Modify carrierIdentification.db database by SQL command

For example (Insert MCCMNC '12345' and gid1 'test' to carrier id 20000):
```
$ adb shell
device:/ $ su
device:/ # DB='/data/user_de/0/com.android.providers.telephony/databases/carrierIdentification.db'
device:/ # sqlite3 $DB "INSERT INTO carrier_id(mccmnc, gid1, carrier_id, carrier_name) VALUES (12345, 'test', 20000, 'test_carrier')"
device:/ # reboot
```

2. Override carrier_list.pb

- Modify carrier_list.textpb directly (Note: You should also bump the version
  number to let TelephonyProvider reload the carrier_list.pb)
- Generate class file by using the carrier id proto(TelephonyProvider/proto/src/carrierId.proto)
  (See https://developers.google.com/protocol-buffers/docs/overview#generating)
- Create a converter by using TextFormat tool to convert textpb to pb
  (Text Format: https://developers.google.com/protocol-buffers/docs/reference/java/com/google/protobuf/TextFormat)
- Rename file to carrier_list_test.pb and push the output file to
    /data/user_de/0/com.android.providers.telephony/files/carrier_list_test.pb
- Reboot the device

Converter example:
```
#!/usr/bin/env python3
from google.protobuf import text_format

# Generated by: protoc -I=./ --python_out=./ ./carrierId.proto
from carrierId_pb2 import CarrierList

def main():
  with open("carrier_list.textpb", "r") as rd:
    carrierList = CarrierList()
    text_format.Merge(rd.read(), carrierList)

    with open("carrier_list.pb", "wb") as wf:
      wf.write(carrierList.SerializeToString())

if __name__ == '__main__':
  main()
```
