Google Access on WP7

I am having problems building an app that can access google accounts. I have the following code that gets the sign in Signin Page page for google accounts and then the access permissions page is also displayed!enter image description here. Once i click on "Allow Access" the app is redirected to error pageError. here are few screenshots so that whoever is trying to help can understand better.. and below is the code that am using 

 private void browseGoogle_Loaded(object sender, RoutedEventArgs e)
    {
        string address = "https://accounts.google.com/o/oauth2/auth" +
        "?client_id=" + "*******.apps.googleusercontent.com" +
        "&scope=" + "https://www.googleapis.com/auth/plus.me" +
        "&response_type=code" +
         "&redirect_uri=" + "https://www.****.com/oauth2callback";

        browseGoogle.Navigate(new Uri(address, UriKind.Absolute));

    }

https://accounts.google.com/o/oauth2/approval?as=634f855389bf10ff&hl=en_GB&xsrfsign=APsBz4gAAAAAUHZvwB3xTqisyv8hEcWem5X3eKvwAHN9 this is the URI its navigating to after allow access is selected/clicked. What does this mean?

 private void browseGoogle_Loaded(object sender, RoutedEventArgs e)
    { 
        try
        {
            StringBuilder autheticateURL = new StringBuilder();
            autheticateURL.Append(GmailSettings.AuthorizeUri).Append("?client_id=").Append(GmailSettings.clientID).Append("&scope=").
                Append(GmailSettings.ScopeValue).Append("&response_type=code").Append("&redirect_uri=").Append(GmailSettings.CallbackUri);
            browseGoogle.Navigate(new Uri(autheticateURL.ToString(), UriKind.Absolute));
        }
        catch (Exception ex)
        {

            Logger.log(TAG, "browseGoogle_Loaded()", ex.Message);

        }
    }

    /// <summary>
    /// Called when the web browser initiates Navigation to various pages 
    /// </summary>
    /// <param name="sender">Browser</param>
    /// <param name="e">Navigating event arguments</param>
    private void browseGoogle_Navigating(object sender, NavigatingEventArgs e)
    {
        try
        {
            string hostName = e.Uri.Host;
            string URL = e.Uri.ToString();

            if (hostName.StartsWith("localhost"))
            {
                NavigationService.Navigate(new Uri("/HomePage.xaml", UriKind.Relative));
            }
        }
        catch (Exception ex)
        {

            Logger.log(TAG, "browseGoogle_Navigating()", ex.Message);

        }
    }

The XAML goes like this

  <phone:WebBrowser x:Name="browseGoogle" Loaded="browseGoogle_Loaded" IsScriptEnabled="true" Navigating="browseGoogle_Navigating" />

My mistakes were two:- 1) as vignesh has mentioned in his comments I was using a wrong Redirect URI. 2)IsScriptEnabled was not at all set in my Web Browser Controls. Once i set it true everything was fine.

Just check the GDrive open-source application code here.

The Authorization View and ViewModel show you how you can make OAuth sign-in with Google credentials.

Download the code, read the pre-build instructions on the site, and test it!
