Unexpected error while launching logcat. Try reselecting the device.

今天在向模拟器部署运行项目时碰到下面的异常：

 

[2012-02-15 13:22:14 - DeviceMonitor] Adb connection Error:An existing connection was forcibly closed by the remote host

[2012-02-15 13:22:14 - Unexpected error while launching logcat. Try reselecting the device.] An existing connection was forcibly closed by the remote host

java.io.IOException: An existing connection was forcibly closed by the remote host

两种解决办法：

1、在命令行下执行如下命令：adb kill-server、adb kill-server

2、在任务管理器中，强制关闭adb.exe，然后重启模拟器
