在尝试了以上所有的解决方案后，我发现在mac os x上:

您必须在系统首选项>> network >> gear图标中检查网络设备的顺序 您必须在/etc/resolv.conf中检查DNS服务器的顺序

然后重新启动你的android模拟器，它应该工作。

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”。

我也有类似的问题。我安装了一个需要INTERNET权限的应用程序(并使用了它)，然后突然就工作了。

朋友们，还要检查一下你是否在某个地方没有通过VPN连接，因为它也会干扰互联网连接。

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”。

我在Web浏览器中没有网络连接，安装Android SDK (Replicant开源版本)后使用WLAN，与禁用LAN卡或DNS服务器不使用DHCP无关。我的问题是:设置->无线和网络->移动网络->“数据启用”没有被选中。这是所有。
