解决问题：
百度google大家多说的是任务管理器 kill掉adb 或者重启adb server，但我任务管理器就没有adb ,猜测是某个程序占用了adb端口。于是按此思路查找。
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 LISTENING 6540
发现6540占用了 5037端口，继续查看6540的task，发现是wandoujia .如下所示
tasklist|findstr "6540"
wandoujia_daemon.exe 6540 Console 1 4,276 K
接下来问题就好解决了，在任务管理器kill掉wandoujia_daemon.exe ，运行android程序，ok .
1.关闭豌豆荚进程
2.adb kill-server
3.adb start-server
4.重启Eclipse
OK
