就我而言，我只需要从“Android SDK和AVD管理器”中启动Android虚拟设备(AVD)，它就可以工作了

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。

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!

我有一台windows 7(64位)的机器，我的模拟器不能工作。在四处寻找之后，我最终静态地将我的路由器添加到网络DNS属性(192.168.1.1)。它开始起作用了。

我解决了这个问题，我禁用了所有的网络连接，除了我正在使用的wifi连接，然后将剩余的启用连接的属性设置为静态分配的DNS地址。(没有DHCP)这是Win7 64bit

我发现在我从Vista x64重建到Win7 x64后，用“擦除用户数据”启动模拟器为我清除了这个问题。
