google maps not displayed

Question

I am getting a problem in implementing a simple HelloGoogleMaps tutorial given at http://developer.android.com/resources/tutorials/views/hello-mapview.html The problem is that everything seems fine, but on running the code, only the grid and google logo appears, also if I add another layer of markers, the markers show up but not the underlying map.
There is internet connection in the emulator as on all the other applications network is connected.
Somebody please help me.
The display on the console is :
