在尝试了以上所有的解决方案后，我发现在mac os x上:

您必须在系统首选项>> network >> gear图标中检查网络设备的顺序 您必须在/etc/resolv.conf中检查DNS服务器的顺序

然后重新启动你的android模拟器，它应该工作。

是的——在win7中使用管理员privs启动模拟器，一切都会很好——或者至少你会在android中获得无线。

我认为有时候重启虚拟设备就足够了。: -)

I think some of the answers may have addressed this, however obliquely, but here's what worked for me. Assuming your problem is occurring when you're on a wireless network and you have a LAN card installed, the issue is that the emulator tries to obtain its DNS settings from that LAN card. Not a problem when you're connected via that LAN, but utterly useless if you're on a wireless connection. I noticed this when I was on my laptop. So, how to fix? Simple: Disable your LAN card. Really. Just go to your Network connections, find your LAN card, right click it and choose disable. Now try your emulator. If you're like me, it suddenly ... works!

如果你用的是Mac，试试这个

去苹果图标->系统首选项->网络 点击齿轮图标，选择“设置服务订单” 将活动接口置于其他接口之前。 重新启动Android模拟器。

我在Win7 64位上遇到了类似的问题。尝试禁用我的hamachi和virtualbox适配器，但没有工作。尝试以管理员身份启动avd，但没有工作。最后，我使用这个网站上的信息禁用了teredo隧道适配器，它工作了: http://www.mydigitallife.info/2007/09/09/how-to-disable-tcpipv6-teredo-tunneling-in-vista/
