经常遇到 Please ensure that adb is correctly located at 'D:\java\sdk\platform-tools\adb.exe' and can be executed. [b]遇到问题描述：[/b] 运行android程序控制台输出     [2012-07-18 16:18:26 - ] The connection to adb is down, and a severe error has occured.     [2012-07-18 16:18:26 - ] You must restart adb and Eclipse.     [2012-07-18 16:18:26 - ] Please ensure that adb is correctly located at 'D:\java\sdk\platform-tools\adb.exe' and can be executed. [b]解决问题：[/b] 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
