Android-ADB server didn't ACK

运行Android模拟器时出现如下错误：

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

You must restart adb and Eclipse.

Please ensure that adb is correctly located at 'X:E:\adt-bundle-windows-x86\sdk\platform-tools\adb.exe' and can be executed.

原因应该是5037的端口被其它程序占用了，可以通过以下方法查找到底是哪个进程占用：

netstat -aon|findstr "5037"

tasklist|findstr "6084"

查了下进程属性和签名，发现是金山手机助手进程，可以选择结束或者直接卸载。

然后重启eclipse，运行即可。
