在Ubuntu11配置Android开发环境的时候，遇到 Could not open Selected VM debug port (8700) 错误，解决方法如下：
sudo vi /etc/hosts
127.0.0.1 localhost 127.0.1.1 kimbook.ubuntu-domain ubuntu
# The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ~
确保第一行为：127.0.0.1 localhost 重启机器，问题解决！
