由于鸿蒙生态还处于初期，官方提供的hdc命令还在不断修改中，部分命令会有变动。 如果文档没来得及更新，欢迎大家提PR和Issue补充指正，觉得有用的可以点 Star⭐️收藏。

HDC（OpenHarmony Device Connector） 是为鸿蒙开发/测试人员提供的用于设备调试的命令行工具，类似Android端的ADB工具。

HDC主要有三部分组成:

  1. hdc client：运行于电脑上的客户端，用户可以在电脑命令终端（windows cmd/linux shell）下请求执行相应的hdc命令。
  2. hdc server：作为后台进程也运行于电脑上，server管理client和设备端daemon之间通信包括连接的复用、数据通信包的收发，以及个别本地命令的直接处理。
  3. hdc daemon：daemon部署于OpenHarmony设备端作为守护进程按需运行，负责处理来自client端请求。

HDC安装

  • 下载 Command Line Tools 并解压

  • hdc文件在command-line-tools/sdk/default/openharmony/toolchains目录下

  • 配置电脑环境变量，以macOS为例，在~/.bash_profile 或者 ~/.zshrc文件中添加如下内容：

export HM_SDK_HOME="/Users/develop/command-line-tools/sdk/default"  //请以sdk实际安装目录为准
export PATH=$PATH:$HM_SDK_HOME/hms/toolchains:$HM_SDK_HOME/openharmony/toolchains
export HDC_SERVER_PORT=7035

也可以自行编译安装：参考鸿蒙官方gitee文档

基本用法

基本语法

hdc -t <connectKey> <command>

如果只有一个设备/模拟器连接时，可以省略掉-t <connectKey> 这一部分，直接使用hdc <command>。在多个设备/模拟器连接的情况下需要指定-t 参数， connectKey可以通过hdc list targets命令获取，对应Android里的adb devices获取的serialNumber。

$ hdc list targets

127.0.0.1:5555    //<IP>:<Port>形式的connectKey ，一般为无线连接的设备或模拟器
FMR0223C13000649

比如给FMR0223C13000649 这个设备安装应用：

$ hdc -t FMR0223C13000649 install entry-default-signed.hap

[Info]App install path:/Users/develop/entry-default-signed.hap, queuesize:0, msg:install bundle successfully.
AppMod finish

注意事项

  • 使用hdc，如果出现异常，可以尝试通过hdc kill -r命令杀掉并重启hdc服务。
  • 如果出现hdc list targets获取不到设备信息的情况，可以通过任务管理器查看是否有hdc进程存在。若进程存在，则通过hdc kill -r命令杀掉该进程。

设备连接管理

FMR0223C13000649		USB	  Connected	  unknown...

输出的内容第一列为设备的connectKey， 第二列是设备连接方式，第三列为设备连接状态，第四列暂时未知

查询设备UDID

$ hdc shell bm get --udid

udid of current device is :
C46284C052AE01BBD2358FE44B279524B508FC959AAB5F4B0B74E42A06569B7E

这个udid在用开发者账号打包时，需要添加这个udid到对应的profile文件中

hdc shell aa start -a {abilityName} -b {bundleName}

  • 其中bundleName可以通过hdc shell bm dump -a获取

  • 其中abilityName可以通过如下命令获取（查看当前任务栈的ability信息）

$ hdc shell aa dump -l    # 运行命令前需要手动打开app

User ID #100
  current mission lists:{
    Mission ID #139  mission name #[#com.kuaishou.hmapp:kwai:EntryAbility]  lockedState #0  mission affinity #[]
      AbilityRecord ID #55
        app name [com.kuaishou.hmapp]

    ],
		...
    "vendor": "快手",
    "versionCode": 999999,

通过这个命令可以获取到很多应用的关键信息，比如reqPermissions，version，abilities等等

清除应用数据

$ hdc shell bm clean -h

usage: bm clean <options>
options list:
  -h, --help                                      list available commands
  -n, --bundle-name  <bundle-name>                bundle name
  -c, --cache                                     clean bundle cache files by bundle name
  -d, --data                                      clean bundle data files by bundle name
  -u, --user-id <user-id>                         specify a user id

清除应用缓存

$ hdc shell bm clean -n {bundleName}  -c

clean bundle cache files successfully.

其中bundleName可以通过hdc shell bm dump -a获取， 比如com.kuaishou.hmapp

清除应用数据

$ hdc shell bm clean -n {bundleName} -d

端口转发

命令 说明
fport ls 展示全部“端口转发主机端口转发数据到设备侧端口”的转发任务
fport local remote 端口转发主机端口转发数据到设备侧端口
fport rm local remote 删除指定“端口转发主机端口转发数据到设备侧端口”的转发任务
rport ls 展示全部“端口转发设备侧端口转发数据到主机端口”的转发任务
rport local remote 端口转发设备侧端口转发数据到主机端口
rport rm local remote 删除指定“端口转发设备侧端口转发数据到主机端口”的转发任务

显示端口转发列表

展示电脑端口转发到手机端口的列表

$ hdc fport ls

FMR0223C13000649    tcp:7912 tcp:7912    [Forward]

本地端口转发到手机

将本地电脑的7913端口转发到手机7912端口

$ hdc fport tcp:7913 tcp:7912

Forwardport result:OK

这个命令非常实用，比如我再手机上实现了一个 http服务，没有这个命令前需要通过手机ip:port来访问，这就需要提前知道手机的wlanIP，执行这个命令后可以直接通过localhost:localPort来访问手机里的服务。

删除端口转发任务

$ hdc fport rm tcp:7913 tcp:7912
Remove forward ruler success, ruler:tcp:7913 tcp:7912

$ hdc fport ls
[Empty]

同理，rport命令表示手机端口转发到电脑端口，我就不一一举例了.

无线调试

方式一：通过手机ip进行连接 (这个方式需要手机和PC处于同一个局域网内)

  1. 在手机上开启tcp端口 hdc -t <serial> tmode port <port>
  2. 连接手机上的tcp端口 hdc tconn <wlan_ip>:<port>
  3. 关闭无线连接 hdc -t <serial> tmode port close

示例

$ hdc -t FMR0223C13000649 tmode port 5555

$ hdc tconn 172.31.124.84:5555   # 这个ip为手机的wlanIp
Connect OK

$ hdc list targets
172.31.124.84:5555
FMR0223C13000649

$ hdc -t 172.31.124.84:5555 tmode port close
Set device run mode successful.

方式二：通过PC的ip进行连接 （这个方式数据线不能拔掉）

  1. 在手机上开启5555端口 hdc -t <serial> tmode port <port>
  2. 将手机的端口转发到PC上 hdc -t <serial> fport tcp:<host_port> tcp:<port>
  3. 连接PC上的端口 hdc tconn 127.0.0.1:{host_port}
  4. 关闭无线连接 hdc -t <serial> tmode port close

示例

$ hdc -t FMR0223C13000649 tmode port 5555

$ hdc -t FMR0223C13000649 fport tcp:5556 tcp:5555
Forwardport result:OK

$ hdc tconn 127.0.0.1:5556
Connect OK

$ hdc list targets
127.0.0.1:5556
FMR0223C13000649

$ hdc -t FMR0223C13000649 tmode port close
Set device run mode successful.

！！注意！！ 方式二中，由于hdc服务只监听了127.0.0.1， 导致其他主机上无法访问，需要将端口再转发一下，可以用socat等工具进行转发

$ socat TCP-LISTEN:5557,fork TCP:localhost:5556

然后在其他主机进行connect

$ hdc tconn <host_ip>:5557
Connect OK

文件传输

命令 说明
file send local remote 从本地发送文件至远端设备
file recv remote local 从远端设备发送文件至本地

从本地电脑发送文件至手机

$ hdc file send ~/layout_407568854.json /data/local/tmp/layout_407568854.json

FileTransfer finish, Size:71792, File count = 1, time:24ms rate:2991.33kB/s

从手机拷贝文件至本地电脑

$ hdc file recv /data/local/tmp/layout_407568854.json ~/layout_407568854.json

[I][2024-05-28 20:15:45] HdcFile::TransferSummary success

屏幕截图

hdc提供了两种截图命令

方式一

$ hdc shell uitest screenCap
// 默认存储路径：/data/local/tmp，文件名：时间戳 + .png。

$ hdc shell uitest screenCap -p /data/local/tmp/1.png
// 指定存储路径和文件名。

【推荐】方式二

$ hdc shell snapshot_display -f /data/local/tmp/2.jpeg
// 截图完成后可以通过 hdc file recv 命令导入到本地

方式二的截图性能效率远远高于方式一

屏幕录屏

相关hdc命令还未支持，官方在开发中。。。

我这边通过python脚本实现了录屏功能，使用方法如下

cd awesome-hdc/scripts
pip3 install -r requirements.txt

python3 screen_recroding.py

打开Scheme (URL)

$ hdc shell aa start -U http://www.baidu.com
start ability successfully.

$ hdc shell aa start -U kwai://home

获取页面布局信息（控件树）

$ hdc shell uitest dumpLayout -p {saveDumpPath}   # 运行命令前需要手动打开app，进入对应页面

DumpLayout saved to:/data/local/tmp/layout_407568854.json
  • -p表示控件树保存的目录，如果不指定，则默认保存在手机的/data/local/tmp目录 /data/local/tmp/layout_407568854.json文件内容如下：
{
    "attributes": {
        "accessibilityId": "",
        "bounds": "[0,0][1260,2720]",
        "checkable": "",
        "checked": "",
        "clickable": "",
        "description": "",

        "scrollable": "",
        "selected": "",
        "text": "",
        "type": ""
    },
    "children": [
    	
      ...
      
    ]

录制用户操作

SmartPerf是一款基于系统开发的性能功耗测试工具，操作简单易用。工具可以检测性能、功耗相关指标，包括FPS、CPU、GPU、RAM、Temp等，通过量化的指标项了解应用性能状况。在开发过程中，使用的可能是有屏或无屏设备，对此SmartPerf提供了两种方式：分别是SmartPerf-Device和SmartPerf-Daemon。SmartPerf-Device适用于有屏设备，支持可视化操作。测试时是通过悬浮窗的开始和暂停来实时展示性能指标数据，保存后可生成数据报告，在报告中可分析各指标数据详情。SmartPerf-Daemon支持shell命令行方式，同时适用于有屏和无屏设备。

  • CPU：每秒读取一次设备节点下CPU大中小核的频点和各核使用率，衡量应用占用CPU资源的情况，占用过多的CPU资源会导致芯片发烫。
  • GPU：每秒读取一次设备节点下GPU的频点和负载信息，衡量应用占用GPU资源的情况，当GPU占用过多时，会导致性能下降，应用程序的运行速度变慢。
  • FPS：应用界面每秒刷新次数，衡量应用画面的流畅度，FPS越高表示图像流畅度越好，用户体验也越好。
  • POWER：每秒读取一次设备节点下的电流及电压信息。
  • TEMP：每秒读取一次设备节点下电池温度、系统芯片温度等信息。
  • RAM：每秒读取一次应用进程的实际物理内存，衡量应用的内存占比情况。
  • snapshot：每秒截取一张应用界面截图。
