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.

如果您在SDK管理器的工具->选项下是代理，则不要配置代理设置。 当你从命令行运行时，添加-http-proxy:

emulator.exe -avd YOUR_AVD_NAME_HERE -http-proxy PROXY:PORT

为我工作。

我认为有时候重启虚拟设备就足够了。: -)

it appears there might be a few reasons why there might be no internet connection for an emulator, in my case i was working from home where i have a wireless connection then came into the office and plugged in direct, however although my wireless connection was disconnected it was not disabled resulting in no emulator connection. my understanding is that when it starts up it looks for a network adapter and if there is any conflict here it might result in no internet connection. to resolve go to Start > Settings > Network Connections right click on Wireless Network Connection (if you are not using wireless) and select disable

检查你是否使用多个互联网连接到你的电脑，比如一个是局域网第二个是调制解调器，所以禁用所有的局域网或调制解调器。

如何设置Android模拟器的Internet选项?

我的服务订单首选项是正确的(Wi-Fi是第一个)，但仍然无法连接。

答案是，从霹雳桥转弯:

系统参数>网络>霹雳桥

然后将“配置IPv4”设置为“关闭”，并应用您的更改。

不需要在模拟器中摆弄访问点。
