Google.apis.Oauth2.v2 Crash

Question

I am using Google Apis to integrate google in WP8 app. I am using this sample.

UserCredential credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets
                {
                    ClientId = App.GoogleClientId,
                    ClientSecret = App.GoogleClientSecret
                }, new[] { Oauth2Service.Scope.UserinfoProfile }, "user", CancellationToken.None);

Above code internally invokes browser and does login and should return to next line.

But I found that It crashes, within browser.

Exception is:

Microsoft.Phone.Controls.WebBrowserNavigationException: Exception of type 'Microsoft.Phone.Controls.WebBrowserNavigationException' was thrown.

Is there any solution to this with using Google.apis library.

Thanks

Solved by adding Google + Permission in App on dev Site.
