我也遇到过同样的问题。 我找到的最简单的解决方法是:

转到Android\Sdk\emulator文件夹，打开命令提示符。 输入emulator -list-avds查看可用的模拟器名称。 输入模拟器-avd name-of-your-device -netdelay none -netspeed full -dns-server 8.8.8.8命令，按“enter”。

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。

Windows 7 32位

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。

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

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!
