Thanks for your help @Drew @divoto. Checked with firebug and whitelisted all the possible domains; that were previously not whitelisted. Here's the list-
<access origin="*.google.com" />
<access origin="*.googleapis.com" />
<access origin="*.gstatic.com" />
<access origin="*.googleusercontent.com" />
<access origin="google.com" subdomains="true"/>
<access origin="googleapis.com" subdomains="true"/>
<access origin="gstatic.com" subdomains="true"/>
<access origin="googleusercontent.com" subdomains="true"/>
