Ubuntu下运行adb devices找不到设备的问题

问题描述

Windows下安装Android studio,里面含有Android SDK,自动包含了adb在内的很多工具包;因开发需要,在WSL中安装了Ubuntu,分别是18和22的,其中也分别安装了Android SDK,官网下载,可以运行adb命令。

本来在Windows下和Ubuntu下都可以直接使用,但是今天上来在Ubuntu下突然找不到设备了,运行adb devices,显示:

List of devices attached
adb server version (41) doesn't match this client (39); killing...
* daemon started successfully

再次运行命令,依旧是空列表:

List of devices attached

问题原因

执行一些简单操作:

adb kill-server
adb start-server

* daemon not running; starting now at tcp:5037
* daemon started successfully

依旧找不到:

List of devices attached

在Windows下试一下:

adb server version (39) doesn't match this client (41); killing...
* daemon started successfully
List of devices attached
c731111d        device

发现虽然也有不匹配的问题,但是是可以找到设备的。

有趣的是,这2个地方adb server,adb client的相反的,逛了一下Stackoverflow,可能是版本的问题。在Windows下和Ubuntu下的adb版本不同。

问题解决

Windows下运行:

C:\Users\xxx\AppData\Local\Android\Sdk\platform-tools\adb --version

显示:

Android Debug Bridge version 1.0.41
Version 34.0.4-10411341
Installed as C:\Users\xxx\AppData\Local\Android\Sdk\platform-tools\adb.exe
Running on Windows 10.0.18363

Ubuntu下运行:

adb --version

显示:

Android Debug Bridge version 1.0.39
Version 1:8.1.0+r23-5~18.04
Installed as /usr/lib/android-sdk/platform-tools/adb

先把Windows的让他不起作用(重命名或者移出环境),在Ubuntu下接着尝试,发现

$ adb start-server

adb server version (41) doesn't match this client (39); killing...

没有启动成功,而这里报的错误是adb所在路径并不是我们所安装的路径【那是什么时候安装的呢?】,我们所安装的只有在自己当时下载解压的位置,检查版本:

~/tools/platform-tools/adb --version

结果:

Android Debug Bridge version 1.0.41
Version 34.0.4-10411341
Installed as /home/gy/tools/platform-tools/adb
Running on Linux 4.4.0-18362-Microsoft (x86_64)

这个才是我们需要的,版本也是正确的
