错误提示 ：

Android Launch!

[2014-02-20 08:42:37 - LoginActivity] The connection to adb is down, and a severe error has occured.

[2014-02-20 08:42:37 - LoginActivity] You must restart adb and Eclipse.

[2014-02-20 08:42:37 - LoginActivity] Please ensure that adb is correctly located at 'F:\android developer\adt-bundle-windows-x86-20130522\sdk\platform-tools\adb.exe' and can be executed.

 

错误原因：端口占用

 

处理方法： 1. 下载端口查看软件，例如TCPView，网上很多。

                   2. 查看adt的端口5037，结束线程。

                   3. 重启eclipse，点击工程运行。多试几次。

 

已有问题发现：QQ音乐，豌豆荚，以及远程登录都有可能占用这5037这个端口。
