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()
|
|
```
