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!

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。

检查你是否使用多个互联网连接到你的电脑，比如一个是局域网第二个是调制解调器，所以禁用所有的局域网或调制解调器。

如何设置Android模拟器的Internet选项?

我在android 4.4上采取了以下措施: 设置->无线和网络->移动网络 ->确认已开启“数据开启”和“数据漫游”。

(编辑) 对于最新版本的Android Studio，你需要使用的模拟器不再在~/Library/Android/sdk/tools文件夹中，而是在~/LibraryAndroid/sdk/emulator中。 如果在尝试下面的解决方案时，您会得到以下消息“PANIC:缺少'x86' CPU的模拟器引擎程序。，然后请参考https://stackoverflow.com/a/49511666更新您的bash环境。

操作系统:Mac OS X El Capitan

IDE: Android Studio 2.2

由于某些原因，我无法通过工作时的AVD访问互联网(可能是代理或网络配置问题)。 对我来说，诀窍是在命令行启动我的AVD，并手动提供谷歌公共DNS 8.8.8.8。

在你的终端中，进入Android sdk的文件夹工具，找到“模拟器”程序:

cd ~/Library/Android/sdk/tools

然后检索avd的名称:

emulator -list-avds

它会返回如下内容:

Android_Wear_Round_API_23
Nexus_10_API_22
Nexus_5X_API_22
Nexus_5X_API_24
Nexus_9_API_24

然后按以下指示启动您想要的AVD:

emulator -avd NameOfYourDevice -dns-server 8.8.8.8

您的AVD已经启动，您应该可以使用互联网了。
