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

服务没有起来。解决方法：http://blog.csdn.net/id19870510/article/details/

1:今天调试android的时候发现一个诡异的问题

 

C:Usersxxxx>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adb server is out of date.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

 

 

adb server is out of date.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：

 

C:Usersxxxx>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

C:Usersxxxxxx>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
