In the samples on github for SDK login with Facebook and Google, you map the user first and last name into different fields. What is the reason you are doing this? I would prefer to use the same fields for first and last name for both logins.
Facebook (sdk property, backendless field):
facebookFieldsMappings.put(“email”, “email”);
facebookFieldsMappings.put(“first_name”, “fb_first_name”);
facebookFieldsMappings.put(“last_name”, “fb_last_name”);
Google(sdk property, backendless field):
googlePlusFieldsMapping.put(“email”, “email”);
googlePlusFieldsMapping.put(“given_name”, “gp_given_name”);
googlePlusFieldsMapping.put(“family_name”, “gp_family_name”);
