Android AOSP：如何在Vehicle hal中初始化VehicleProperty:：AUDIO_VOLUME属性（.DefaultConfig.h中的initialValues）？

试图将音频音量属性添加到演示车辆hal代码中，该代码位于

/hardware/interfaces/automotive/vehicle/2.0/default/impl/vhal\u v2\u 0/

文件名：DefaultConfig.h 尝试像下面这样添加，但它正在崩溃

    {.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)  } }
    },

中定义的音频音量属性

/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),

参考OSP代码可在

中使用hidl\u vec来打包初始值

例如：

{.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 = hidl_vec<int32_t> {toInt(VehicleAudioContextFlag::MUSIC_FLAG), 80, toInt(VehicleAudioVolumeState::STATE_OK) }}
    },

{.config=
{
.prop=toInt（车辆属性：：音频音量），
.access=VehiclePropertyAccess:：读写，
.changeMode=车辆属性changeMode:：在更改时，
.configArray={toInt（车辆音频通信extFlag:：MUSIC\u FLAG），toInt（车辆音频通信容量FLAG:：仅限主音量），0,0100}，
},
.initialValue={.int32Values=hidl_vec{toInt（车辆音频接口标志：：音乐标志），80，toInt（车辆音频接口标志：：状态确定）}
},

因为此属性需要INT32_VEC值。

什么是

hidl_VEC

？
