My machine is using a WiFi connection for internet, and the LAN card is idle. it\'s not behind a proxy or firewall, but somehow, my emulator\'s browser isn\'t loading any page.
Just right click your eclipse.exe file and click "run as administrator" then whenever emulator will start from eclipse while running your app then you will be able to access internet inside it..it will use host's internet so that should be on..if you are using command line environment then do same with your command prompt ..(this is for windows)..there is no need of proxy or dns setting etc..i dont know about other platforms but it worked for me in windows.. hope this helps :)
