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.

环境:Windows 7 64位

在我的例子中，我必须在verbose模式下运行模拟器(emulator -verbose -avd Nexus_6_API_25)来找出模拟器检测到两个DNS服务器的事实，如下所示。

模拟器:找到2个DNS服务器:192.168.3.227 192.168.1.1

在检测到的两个DNS服务器中，只有一个有互联网连接，这是模拟器无法上网的原因。

为了成功连接android模拟器到互联网，没有互联网连接的DNS服务器必须从控制面板\网络和互联网\网络连接中禁用

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。

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

读完这篇文章后，我决定看看我的“网卡”。我把它放在引号里，因为像许多人一样，我正在为Hamachi和virtual Box等设备运行虚拟网卡。在我禁用了Hamachi之后，我可以使用互联网了。我的猜测是模拟器选择第一个可用的nic，而不管它是否是虚拟的。现在来看看我是否可以重新安排我的nic订单而不撕裂我的盒子。

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
