title: Using custom login button with Twitter Fabric?
body: <p>I have been trying to use a normal button to execute the authentication process with the twitter sdk but it does not seem to work. Anyone have tried anything similar?</p>
  
  <ul>
  <li>I have correctly setup the API keys, etc..</li>
  <li>The login process execute correctly but the callback part seems not to be called.</li>
  <li>None of my logs are executed (Neither the success or failure part)</li>
  </ul>
  
  <p>The code</p>
  
  <pre><code>buttonTwitterLogin.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View view) {
  
          Twitter.logIn(LoginActivity1.this, new Callback&lt;TwitterSession&gt;() {
              @Override
              public void success(Result&lt;TwitterSession&gt; twitterSessionResult) {
                  Log.i(TAG, "success");
                  Log.i(TAG, twitterSessionResult.toString());
              }
  
              @Override
              public void failure(TwitterException e) {
                  Log.e(TAG, "failed");
              }
          });
      }
  });
  </code></pre>
