adb server is out of date.killing

今天想调试google官方给的sip-deamon，结果启动不了adb

C:\Users\xxxx>adb start-server
adb server is out of date.  killing...
ADB server didn't ACK
* failed to start daemon *

一直这样报错，百度一下，才知道是端口被占用了。

C:\Users\xxxx>adb nodaemon server
cannot bind 'tcp:5037'

查看是哪个端口被占用

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

然后结束掉pid为4236的进程

taskkill /pid 4236
