[android-porting] AOSP: How to initialize the VehicleProperty::AUDIO_VOLUME property (.initialValues in the DefaultConfig.h) in vehicl hal ?

[Sibiraj T]

Trying to add AUDIO_VOLUME property to the demo vehicle hal code present in 
/hardware/interfaces/automotive/vehicle/2.0/default/impl/vhal_v2_0/

File name: DefaultConfig.h
tried adding like below, but it is crashing.

        {.config =
            {
                .prop = toInt(VehicleProperty::AUDIO_VOLUME),
                .access = VehiclePropertyAccess::READ_WRITE,
                .changeMode = VehiclePropertyChangeMode::ON_CHANGE,
                .configArray = { 
toInt(VehicleAudioContextFlag::MUSIC_FLAG), 
toInt(VehicleAudioVolumeCapabilityFlag::MASTER_VOLUME_ONLY),0,0,100 },
            },
            .initialValue = {.int32Values = { 
toInt(VehicleAudioContextFlag::MUSIC_FLAG), 80, 
toInt(VehicleAudioVolumeState::STATE_OK)  } }
        },

AUDIO_VOLUME property as defined in 
/hardware/interfaces/automotive/vehicle/2.0/types.hal
     * @change_mode VehiclePropertyChangeMode:ON_CHANGE
     * @access VehiclePropertyAccess:READ_WRITE
     * @config_flags all audio contexts supported.
     */
    AUDIO_VOLUME = (
        0x0901
        | VehiclePropertyGroup:SYSTEM
        | VehiclePropertyType:INT32_VEC
        | VehicleArea:GLOBAL),


reference OSP code available in http://androidxref.com/8.0.0_r4/xref/

Thanks in advance.!!
