eclipse adb问题

run On device 时又如下问题

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

按照所查操作提示

----------------------------------------

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.

-------------------------------------------------------------------

可是

adb start-server 时出了如下问题

adb server is out of date.  killing...

ADB server didn't ACK

* failed to start daemon *

然后进入任务管理器，发现一个tadb.exe的可疑进程，将其终止

adb start-server
成功
