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。

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

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。)

您需要使用“控制面板\所有控制面板项\网络连接”与模拟器共享您的笔记本电脑Internet，并选择笔记本电脑的活动Internet源，然后右键单击然后共享选项卡。在这里勾选共享复选框，如果需要，选择模拟器网络，如果列出。

在Android模拟器中，打开飞机模式，然后再关闭，对我来说很管用。

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.
