Android Automotive模拟器缺失车辆数据等扩展控件问题求助

补充必要的系统包 #

除你已添加的android.hardware.automotive.vehicle@2.0-service，还需加入以下相关包以启用缺失功能：

PRODUCT_PACKAGES += \
    android.hardware.automotive.vehicle@2.0-service \
    CarDataProvider \
    SensorReplayService \
    CarRotaryService \
    AutomotiveSimulatorControls \
    android.hardware.sensors@2.0-service.multihal \
    android.hardware.automotive.vehicle@2.0-fake

完善权限与特性配置 #

添加车载模拟器所需的额外权限声明：

PRODUCT_COPY_FILES += \
    frameworks/native/data/etc/android.hardware.type.automotive.xml:$(TARGET_COPY_OUT_VENDOR)/etc/permissions/android.hardware.type.automotive.xml \
    frameworks/native/data/etc/android.hardware.sensors.xml:$(TARGET_COPY_OUT_VENDOR)/etc/permissions/android.hardware.sensors.xml \
    packages/services/Car/car_product/build/etc/permissions/com.android.car.xml:$(TARGET_COPY_OUT_SYSTEM)/etc/permissions/com.android.car.xml

启用模拟器特定车载配置 #

添加模拟器专用车辆HAL配置，确保功能激活：

PRODUCT_PROPERTY_OVERRIDES += \
    ro.automotive.emulator=true \
    ro.hardware=automotive_emulator \
    ro.vehicle.hal.interface=2.0

验证与重建 #

• 清理构建缓存：make clean
• 重新执行构建命令（如make -j$(nproc)）
• 启动模拟器后，进入扩展控件面板检查车辆数据、传感器重放、车载旋钮功能是否正常显示
