The connection to adb is down, and a severe error has occured.问题解决

在运行时遇到问题描述：

运行android程序控制台输出

[2020-05-24 19:29:38 - NetMaster] The connection to adb is down, and a severe error has occured.
[2020-05-24 19:29:38 - NetMaster] You must restart adb and Eclipse.
[2020-05-24 19:29:38 - NetMaster] Please ensure that adb is correctly located at 'E:\adt-bundle-windows-x86_64-20140702\sdk\platform-tools\adb.exe' and can be executed.

1、任务管理器 kill掉adb 或者重启adb server

2、查看任务管理器没有adb，猜测应该是某个程序占用了adb端口，接下来我列出详细步骤。

第一步：

打开cmd输入 netstat -aon|findstr “5037” （5037为adb默认端口）

 TCP    127.0.0.1:5037         0.0.0.0:0              LISTENING       19296

这时候我们发现 19296占用了 5037端口。

第二步：

继续查看19296的task：

输入 tasklist|findstr “19296”

hwtransport.exe              19296 Console                    4      8,776 K

我们发现是hwtransport.exe占用。

第三步：

直接在任务管理器里面kill掉或

taskkill /f /im hwtransport.exe

Tip：

tasklist 可以找到任务管理器所有进程
taskkilll /f /im 程序名1.exe /f /im 程序名2.exe … 可以kill掉多个程序
重新开启adb （adb kill-server ，adb start-server）

希望对您有帮助！
