@Anil Sagar,

Thanks for your kind response.

I am using google cloud endpoinds. The google cloud endpoinds accepting only google authorized request.Not accepting facebook authorized request.

Return error

No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘http://localhost’ is therefore not allowed access. The response had HTTP status code 400.

Then another error 401

I am already login via facebook. But return User must be login.
