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

启动android模拟器时.有时会报The connection to adb is down, and a severe error has occured.的错误.在网友说在任务管理器上把所有adb.exe关闭掉.重启eclipse.但试过不管用.所以在外国网站上找到一种可行的方法:

1.先把eclipse关闭.

2.在管理器转到你的android SDK 的platform-tools下, 如图:


3.键入adb kill-server ,如果adb关闭了会提示 server not running *

4.再输入 adb start-server  如果不成功会提示 daemon not running. starting it now on port  ***的
   而如果成功的话不提示任何语句的.这时再重新打开eclipse就可以正常运行模拟器的了.
