Getting Daily Limit for unauthenticated use Exceeded - xamarin

Question

Getting Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup
when executing the following code given in the Xamarin demo
async void OnAuthenticationCompleted (object sender, AuthenticatorCompletedEventArgs e)
{
if (e.IsAuthenticated) {
// If the user is authenticated, request their basic user data from Google
// UserInfoUrl = https://www.googleapis.com/oauth2/v2/userinfo
var request = new OAuth2Request ("GET", new Uri (Constants.UserInfoUrl), null, e.Account);
var response = await request.GetResponseAsync ();
if (response != null) {
// Deserialize the data and store it in the account store
// The users email address will be used to identify data in SimpleDB
string userJson = response.GetResponseText ();
App.User = JsonConvert.DeserializeObject<User> (userJson);
e.Account.Username = App.User.Email;
AccountStore.Create ().Save (e.Account, App.AppName);
}
}
// If the user is logged in navigate to the TodoList page.
// Otherwise allow another login attempt.
App.SuccessfulLoginAction.Invoke ();
}
This is the error I am getting
"error":{
"errors": [
{
"domain": "usageLimits",
"reason": "dailyLimitExceededUnreg",
"message" :"Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."
"extendedHelp" : "https://code.google/apis/console"
}
],
"code":403,
"message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."
}

Answer 1

I corrected the redireturl to "http://example.com/oauth2callback" and in the ios project modified the ATS setting by adding the following key in info.plist
NSAppTransportSecurity -- Dictionary
NSAllowsArbitraryLoadsInWebContent -- Boolean -- Yes
