This module tests the Vehicle HAL using adb socket.
Protocol Buffer:
This module relies on VehicleHalProto_pb2.py being in sync with the protobuf in the VHAL.
If the VehicleHalProto.proto file has changed, re-generate the python version using
a command of the form:
protoc -I=<proto_dir> --python_out=<out_dir> <proto_dir>/VehicleHalProto.proto
For example:
protoDir=~/android/master/hardware/interfaces/automotive/vehicle/2.0/default/impl/vhal_v2_0/proto
outDir=~/android/master/packages/services/Car/tools/emulator
protoc -I=$protoDir --python_out=$outDir $protoDir/VehicleHalProto.proto
