您尝试过使用管理权限启动模拟器吗?它适用于我，我运行的是Windows 7 64bit)

I have Mac OS X 10.7.2, Eclipse Helios Service Release 2. I also work via Proxy and my IP settings are via DHCP. I solved this issue firstly using this article http://www.gitshah.com/2011/02/android-fixing-no-internet-connection.html, then I removed Emulator settings and just go to Run->Run Configurations->Target->Additional Emulator Command Line Options and type there -http-proxy xxx.xx.111.1:3128 . Also I would like to say that when I typed also a DNS like this: -dns-server xxx.xx.111.1 -http-proxy xxx.xx.111.1:3128 it did not work, but when I removed DNS it worked. Also I would like to note, that Additional Emulator Command Line Options are not visible without scrolling to the bottom of that window. I also want to note, that when you change emulator options, all apps will work. But If you write Additional Emulator Command Line Options, you need to write them every time for every app target in Run Configurations.

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。
