我有这个问题，由于网络变化后，我打开模拟器。如果您在启动模拟器后更改了WiFi，则只需重新启动模拟器即可获得互联网访问

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.

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?

我认为有时候重启虚拟设备就足够了。: -)

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”。

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
