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

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!

如果你用的是Mac，试试这个

去苹果图标->系统首选项->网络 点击齿轮图标，选择“设置服务订单” 将活动接口置于其他接口之前。 重新启动Android模拟器。

我没有使用代理……然而，我正在使用一个脚本…在这附近。我在公司的防火墙后面

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。

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。
