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.
还有一种情况,真机调试的时候,你开了腕豆夹,导致端口冲突了,前面一直没留意这个问题 ，解决办法：安装完手机的驱动后，关闭腕豆夹,重启eclipse，应该就可以了。腕豆夹与eclipse一般不同时打开！
