• create gcp project in console developers

• create a jks and register in the same gcp project as android OAuth client ID

  • this value is required by android to use internal s.o services
  • this value must be used to sign the apk : signingConfigs in build.graddle

• in the same gcp project, create an WEB OAuth client ID

  • you will get a client id and client secret
  • origin and redirect are not required
  • origin and redirect accepts any string value with http url format
  • origin and redirect empty or with value are required to exchange the oauth code by an access_token:

https://accounts.google.com/o/oauth2/token
 ?code={authorization_code}
 &client_id={client_id}
 &client_secret={client_secret}
 &redirect_uri={redirect_uri}
 &grant_type=authorization_code
