android-出错之-The connection to adb is down, and a severe error has occured.

cmd跳到sdk tools文件路径下
adb kill-server
然后再adb start-server

1:今天调试android的时候发现一个诡异的问题

[html] view plaincopy

C:\Users\xxxx>adb start-server

adb server is out of date. killing...

ADB server didn't ACK

* failed to start daemon *

adb 不管执行 shell devices 还是logcat 都会报错

[html] view plaincopy

adb server is out of date. killing...

究其源就是adb server没启动

到stackoverflow上查了一下 经过分析整理如下：

[html] view plaincopy

C:\Users\xxxx>adb nodaemon server

cannot bind 'tcp:5037'

原来adb server 端口绑定失败

继续查看到底是哪个端口给占用了

[html] view plaincopy

C:\Users\xxxxxx>netstat -ano | findstr "5037"

TCP 127.0.0.1:5037 0.0.0.0:0 LISTENING 4236

TCP 127.0.0.1:5037 127.0.0.1:49422 ESTABLISHED 4236

TCP 127.0.0.1:49422 127.0.0.1:5037 ESTABLISHED 3840

打开任务管理器kill掉4236 这个进程。ok

至此问题解决了
