确保飞行模式是关闭的。我一直试图连接互联网很长一段时间，才意识到哪里出了问题。

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。

这个问题有不同的解决办法。其中之一，我将向您展示我的实验和结果，使用最近的android studio和2017年下载的AVD图像。

你要做的第一件事是从android工作室启动你的AVD。(在我的情况下，我选择NEXUSAPI25安卓7.1图像) 转到设置->无线和网络->蜂窝网络->接入点->(+)按add ->输入以下如果你没有NTLM代理或代理在所有(这意味着你是直接连接) a.添加apn名称为myAPN B.添加apn服务器=> WWW C.保存并尝试浏览互联网。

如果这不起作用，在你的环境变量中添加“ANDROID_SDK_ROOT”

然后，使用模拟器命令启动AVD，如下所示

模拟器-avd Nexus25 -dns-server 8.8.8.8

对于那些使用NTLM代理的人，接下来我将向您展示它如何为我工作。 将Android_sdk_root路径添加到环境变量中。这使得命令行代码像使用AVD名称一样读取成功。 使用以下命令启动模拟器

>模拟器-avd Nexus_5X_API_25 -http-proxy http://username:password@ipaddress:端口

输入

我不确定这是否是你的问题，但这是我解决我的问题的方法。

在启动模拟器时，我总是有这个“没有找到DNS服务器”的错误，并对谷歌进行了大量的研究，但无济于事。不管怎样，我在某个地方发现了一个帖子(再也找不到它了)，它说nic的数量，DNS条目的数量会影响模拟器。此外，知道模拟器使用Windows API函数(GetNetworkParams())来解析DNS条目，我不能依赖于% Windows %\System32\Hosts文件。

然而，我在nic属性中(在Windows 7上)发现我指定了一个静态IP，但没有DNS条目。因此，我从路由器获取了DNS条目，并将它们插入NICs属性中。我重新启动模拟器，现在它正在使用正确的DNS条目!

我现在可以使用模拟器的互联网连接，它的工作效果非常好!

希望能有所帮助!

I have Mac OS X 10.7.2, Eclipse Helios Service Release 2. I also work via Proxy and my IP settings are via DHCP. I solved this issue firstly using this article http://www.gitshah.com/2011/02/android-fixing-no-internet-connection.html, then I removed Emulator settings and just go to Run->Run Configurations->Target->Additional Emulator Command Line Options and type there -http-proxy xxx.xx.111.1:3128 . Also I would like to say that when I typed also a DNS like this: -dns-server xxx.xx.111.1 -http-proxy xxx.xx.111.1:3128 it did not work, but when I removed DNS it worked. Also I would like to note, that Additional Emulator Command Line Options are not visible without scrolling to the bottom of that window. I also want to note, that when you change emulator options, all apps will work. But If you write Additional Emulator Command Line Options, you need to write them every time for every app target in Run Configurations.
