遇到的第一个问题：

[2013-01-25 22:57:32 - MyFirstApp] ------------------------------
[2013-01-25 22:57:32 - MyFirstApp] Android Launch!
[2013-01-25 22:57:32 - MyFirstApp] The connection to adb is down, and a severe error has occured.
[2013-01-25 22:57:32 - MyFirstApp] You must restart adb and Eclipse.
[2013-01-25 22:57:32 - MyFirstApp] Please ensure that adb is correctly located at 'D:\AndroidDevelop\adt-bundle-windows-x86\sdk\platform-tools\adb.exe' and can be executed.

解决办法：
cmd跳到sdk tools文件路径下
adb kill-server
然后再adb start-server

就像下图里这样：

有时候命令行还是很起作用的。
