adb shell 错误

使用adb shell提示adb server is out of date. killing...?

#####是ADB端口被占用了

先执行adb nodaemon server ，查看adb server的端口是多少

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

再执行下netstat -ano | findstr "5037"

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     搜索4236  
  TCP    127.0.0.1:49422        127.0.0.1:5037         ESTABLISHED     3840

最后执行tskill 4236即可。
