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

[2015-10-07 09:43:43 - listView_Demo] You must restart adb and Eclipse.

[2015-10-07 09:43:43 - listView_Demo] Please ensure that adb is correctly located at 'F:\java\adt-bundle-windows-x86-20130717\sdk\platform-tools\adb.exe' and can be executed.

网上很多解决方法，有的是5037端口被占用，有的adb为启动成功，如果为启动成功，那就重启ecplise

还有一种就是加载sdk路径加载错误
