title: Xamarin Android Xamarin.Auth - Twitter
body: <p>I have a problem with implementing twitter login in my Xamarin Android.
  I have included Xamarin.Auth component and it works fine for Facebook.
  Fot twitter auth.Completed event is not called...
  I have created sample app on twitter dev portal.</p>
  
  <p>Here is my code from the app:</p>
  
  <pre><code>private void LoginTwitter()
      {
          var auth = new OAuth1Authenticator(
                    consumerKey: "3v7rOXkdexGYhQmr3HVhtGgPO",
                    consumerSecret: "mGhRjee87tAp4X0vHUmMIohWoYy0JGg9zFGyin7CigFP64y3j5",
                    requestTokenUrl: new Uri("https://api.twitter.com/oauth/request_token"),
                    authorizeUrl: new Uri("https://api.twitter.com/oauth/authorize"),
                    accessTokenUrl: new Uri("https://api.twitter.com/oauth/access_token"),
                    callbackUrl: new Uri("http://twitter.com")
                );
          auth.AllowCancel = true;
          StartActivity(auth.GetUI(this));
          auth.Completed += (s, eventArgs) =&gt;
          {
              if (eventArgs.IsAuthenticated)
              {
  
                  Account loggedInAccount = eventArgs.Account;
                  //save the account data for a later session, according to Twitter docs, this doesn't expire
                  AccountStore.Create(this).Save(loggedInAccount, "Twitter");
              }
          };
      }
  </code></pre>
  
  <p>I hope someone will help.</p>
