android中The connection to adb is down的问题和解决

问题：

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 'D:\adt-bundle-windows-x86_64-20130917\sdk\platform-tools\adb.exe' and can be executed.

解决办法：(先尝试第二种，如果不可以再尝试第一种）

（1）在任务管理器中关闭adb,然后重启eclipse

 (2）在cmd中进入安装目录下的（D:\adt-bundle-windows-x86_64-20130917\sdk\platform-tools），然后adb -killserver和adb -startserver
