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

网络获取资料所得：
运行eclipse执行android应用，控制台报错：

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 'E:\setups\android\android-2.1_r01-windows\tools\adb.exe' and can be executed.

 

 

关掉eclipse，查看任务管理器，关闭tabd.exe，重启即可
