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.

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
