Hi Eitan,
Finally i have found the answer, it's not opening the Google Chrome as default browser for SAP Screen, but it's integrating the Google Service into the IE for the SAP.
And also remove the IE from the system default application list.
->>Control Panel\Programs\Default Programs
And Change the Setting from 'Set Program Access and Computer Defaults'.
Now I am getting the Google Services related pages in SAP Screen also.
And also activate the Google Service from the SAP GUI Option, after that the page is opening in SAP Screen, which contains the Google services.
Regards.
Praveer.
