我有这个问题，由于网络变化后，我打开模拟器。如果您在启动模拟器后更改了WiFi，则只需重新启动模拟器即可获得互联网访问

我在虚拟windows 7上也遇到了同样的问题。

转到网络连接 Alt >高级>高级设置… 在第二个选项卡将互联网网络界面放在顶部

希望对大家有帮助 多亏了

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!

在eclipse中转到DDMS

在DDMS下选择模拟器控制，其中包含电话状态 在电话状态包含数据——>选择Home，这将启用您的互联网连接，如果您想禁用模拟器的互联网连接，那么——>选择None

(注意:只有当运行eclipse的PC/笔记本电脑有活跃的internet连接时，才会启用internet连接。)

我认为有时候重启虚拟设备就足够了。: -)

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.
