如果您在SDK管理器的工具->选项下是代理，则不要配置代理设置。 当你从命令行运行时，添加-http-proxy:

emulator.exe -avd YOUR_AVD_NAME_HERE -http-proxy PROXY:PORT

为我工作。

在Android模拟器中，打开飞机模式，然后再关闭，对我来说很管用。

就我而言，我只需要从“Android SDK和AVD管理器”中启动Android虚拟设备(AVD)，它就可以工作了

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?

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!

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
