adb not responding. if you'd like to retry then please manually kill adb.exe and click 'restart'，restart

最近Android Studio老是提示一个问题，adb not responding. if you'd like to retry then please manually kill adb.exe and click 'restart'，restart没用，kill-server和start-server也没用，最后发现，某手机助手程序偷偷占用了adb运行的端口号5037...

知道原因之后那就简单了，查看那个程序占用5037端口 ->运行cmd，netstat -ano | findstr "5037",果不其然
