Answer 1

Finally i got a solution by doing the research over the available codes from xamarin forum and stackoverflow. I made use of the OAuth2Authenticator

1. Register in google developer console as webapplication instead of installed application(android)* provide the redirect url with valid url ("http://abcd.com/xyz.aspx") same should be used in the application code.

2. On authentication complete it will return access_token

3. By using the access_token make the REST request to get user complete information (https://www.googleapis.com/oauth2/v1/userinfo?access_token=" + accessTokenValue + “.)

4. Deserialize the json response to get information in object.

*If we registered in developer console as installed application(like android) after making OAuth2Authenticator request it will show window with message please copy this code switch to your application and paste it there [code] manually need to close the window and proceed to authentication. to get ride of this webapplication type is choosen.
