Error :: The URL could not be found

I can not open browser in my Android Emulator, It gives Error like this,

onReceivedError -2 http://www.google.com/ The URL could not be found. 

Can anyone tell me how this resolve.

Thanks.

Sometimes, after running for a while, the Android emulator looses it's internet connection for no apparent reason. Restarting the emulator fixes the problem.
