title: Get Twitter user email using Fabric SDK
body: <p>I'm logging in with twitter using Fabric. </p>
  
  <p>This is how I fetch the user data:</p>
  
  <pre><code>loginButton.setCallback(new Callback&lt;TwitterSession&gt;() {
                  @Override
                  public void success(Result&lt;TwitterSession&gt; result) {
                      // Do something with result, which provides a TwitterSession for making API calls
                      AccountService ac = Twitter.getApiClient(result.data).getAccountService();
                      ac.verifyCredentials(true, true, new Callback&lt;com.twitter.sdk.android.core.models.User&gt;() {
                          @Override
                          public void success(Result&lt;com.twitter.sdk.android.core.models.User&gt; result) {
                              String imageUrl = result.data.profileImageUrl;
                              String email = result.data.email;
                              String userName = result.data.name;
                              System.out.println(imageUrl);
                              System.out.println(email);
                              System.out.println(userName);
                          }
  
                          @Override
                          public void failure(TwitterException e) {
  
                          }
                      });
  
                  }
  </code></pre>
  
  <p>This is working fine, except that the <code>email</code> variable is <code>null</code> when I print to log. Is there an other way of fetching the user email?  </p>
