Android :: Internet Connection In Emulator Always Displays Connected State

I tried in many ways to check Internet connection in my android emulator

CODE:.........

Even if i disable Internet connection in my system ,my code seems to display Connected state
so i guessed this may work

CODE:.......

But the above code also displays "Connection Present" even when i disconnect Internet cables. Please help to find a correct way to do this .I have ACCESS_NETWORK_STATE and INTERNET permission in my manifest file
