Android开发，The connection to adb is down, and a severe error has occurred.

有时候运行Android项目的时候会出现以下的问题：



[2011-11-22 15:17:07 - HelloWorld] ------------------------------

[2011-11-22 15:17:07 - HelloWorld] Android Launch! 

[2011-11-22 15:17:07 - HelloWorld] The connection to adb is down, and a severe error has occured. 

[2011-11-22 15:17:07 - HelloWorld] You must restart adb and Eclipse. 

[2011-11-22 15:17:07 - HelloWorld] Please ensure that adb is correctly located at 'C:\Android\android-sdk\platform-tools\adb.exe' and can be executed.



出现以上这种情况，是因为某些时候，android项目被强制关闭或者崩溃了，导致adb.exe运行不正常，这时候只重启eclipse还不行，应该直接把adb.exe进程重启，在任务管理器找到adb.exe，并且结束之！，然后再重启eclipse，然后再运行就好了
