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!

如果你使用的是MacOS 2.2，并且你一直看到关于数据连接的错误，尝试上面的方法，它是有效的。

除了LAN，我通过Sys Prefs删除了所有的网络接口 尽管我的DNS是由DHCP提供的，但我只用一台服务器重新输入了DNS 我在命令行上使用-http-proxy来指定一个

它从办公室开始工作。唷。

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。

(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。

环境:Windows 7 64位

在我的例子中，我必须在verbose模式下运行模拟器(emulator -verbose -avd Nexus_6_API_25)来找出模拟器检测到两个DNS服务器的事实，如下所示。

模拟器:找到2个DNS服务器:192.168.3.227 192.168.1.1

在检测到的两个DNS服务器中，只有一个有互联网连接，这是模拟器无法上网的原因。

为了成功连接android模拟器到互联网，没有互联网连接的DNS服务器必须从控制面板\网络和互联网\网络连接中禁用
