Android Automotive（八）调试方法

Android Automotive的框架前面已经介绍完了，今天介绍一下关于Android Automotive的调试方法。

EmbeddedKitchenSinkApp

EmbeddedKitchenSinkApp 是Android Automotive提供的一个应用层Demo程序，在应用里实现大CAR API的大量接口调用，并提供界面展示。

关于接口调用以及显示效果都可以参考这个应用程序。

代码路径：packages/services/Car/tests/EmbeddedKitchenSinkApp

vehicle-hal-tool

Android8支持的(AnroidR上已删除)

hardware/libhardware/tests/vehicle/vehicle-hal-tool.c
加载车载 HAL 并执行简单操作的命令行原生工具。它有助于系统在开发的早期阶段启动并运行。

carservice_test

packages/services/Car/tests/carservice_test/

UT Test。包含使用模拟车载 HAL 属性进行的汽车服务测试。每个属性的预期行为都会在测试中实现，这是了解预期行为的绝佳起点。

vehiclehal_test

packages/services/Car/tests/vehiclehal_test
UT Test VehicleHALTest 测试车辆属性接口，调用CarPropertyManager

emulator模拟器

Android Automotive提供了一个测试车辆属性接口的模拟器，文件在packages/services/Car/tools/emulator目录下。可以模拟几个车辆属性变化。

需要PyQt4支持，python2.x版本。运行命令：

python gui.py

在这里插入图片描述

其它工具

python code tool
packages/services/Car/tools
在packages/services/Car/tools/emulator处理模拟器，还有一些辅助工具。
ply
代码路径 external/ply/ply
一个python库，用来解析hal文件

ADB命令

adb命令，通过dumpsys activity service的实现，来完成一个虚拟属性事件的上报。

通过命令模拟车辆属性上报命令：

非GLOBAL属性：

adb shell dumpsys activity service CarService inject-vhal-event <property> <zone> <value>

GLOBAL属性：

adb shell dumpsys activity service CarService inject-vhal-event <property> >value>

[property] 查看javadoc, 对应车辆属性的十进制值
[zone] 参考区域值
[value] 自行设置

支持类型

BOOLEAN，INT32，INT32_VEC，FLOAT，FLOAT_VEC

BOOLEAN
INT32
INT32_VEC
FLOAT
FLOAT_VEC

例子
传入INTl类型：

adb shell dumpsys activity service CarService inject-vhal-event <property> 1

传入数组，逗号分割：

adb shell dumpsys activity service CarService inject-vhal-event <property> 1,2,3

传入BOOLEAN：

TRUE : adb shell dumpsys activity service CarService inject-vhal-event <property> 1

FALSE: adb shell dumpsys activity service CarService inject-vhal-event <property> 0
