The connection to adb is down, and a severe error has occured

编程的时候

运行android程序控制台输出

 [2014-4-05 16:18:26 - ] The connection to adb is down, and a severe error has occured.[2014-4-05 16:18:26 - ] You must restart adb and Eclipse.[2013-4-05 16:18:26 - ] Please ensure that adb is correctly located at 'D:javasdkplatform-toolsadb.exe' and can be executed.

1. 任务管理器 kill掉adb 或者重启adb server，如果任务管理器就没有adb ,应该是某个程序占用了adb端口。

   5037为adb默认端口 查看该端口情况如下：

   netstat -aon|findstr "5037"

   TCP 127.0.0.1:5037 0.0.0.0:0 SYN_SENT 3772

   发现3772占用了 5037端口，继续查看3772的task，发现是wandoujia .如下所示

   tasklist|findstr "3772"

   wandoujia_daemon.exe 3772 Console 1 38,636 K

   接下来问题就好解决了，在任务管理器关闭到掉wandoujia_daemon.exe ，运行android程序，ok

2. 2

   将android-sdk-windows/platform-tools和android-sdk-windows/tools都加到环境变量中去。（classpath或者path)
