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。

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。

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。

当我第一次运行模拟器时，我遇到了这个问题，我通过设置dns服务器来解决

Library/Android/sdk/platform-tools/adb shell getprop net.dns1

获取模拟器10.0.2.3的当前DNS服务器

然后设置它到我的局域网dns服务器

Library/Android/sdk/platform-tools/adb shell setprop net.dns1 192.168.1.1

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
