title: Retrofit handling errors from server
body: <p>Just tied Retrofit and it is great. Don't want to invent something new so is there any way to handle all possible errors in <code>failure()</code>.
  Or the only way is to check all statuses and for example show Dialogs?</p>
  
  <pre><code> @Override
    public void failure(RetrofitError error) {
  
    }
  </code></pre>
