Hi Sandeep,
Although there are undoubtedly people on this site who can help you, the primary focus of iFixit is hardware repairs of people's devices, whether it's laptops, cellphones, televisions, appliances, etc. There are probably other forums more focused on software issues like problems with the synching Google accounts that would be more appropriate for your question.
However, in the spirit of the iFixit community, I'd like to point you to Google's account synch troubleshooting page and suggest you try the steps outlined there.
