title: How do I add UrlEncodedFormEntity to a MultipartEntityBuilder
body: <p>I have a file that I want to upload so I have your standard MultipartEntityBuilder like this:</p>
  
  <pre><code>MultipartEntityBuilder multiPartEntity = MultipartEntityBuilder.create();
  multiPartEntity.addBinaryBody("file", file);
  </code></pre>
  
  <p>I also have some form params that I send with the POST like this:</p>
  
  <pre><code>ArrayList&lt;NameValuePair&gt; postParameters = new ArrayList&lt;NameValuePair&gt;();
  postParameters.add(new BasicNameValuePair("userId",userId));
  postParameters.add(new BasicNameValuePair("taskId",taskId));
  new UrlEncodedFormEntity(postParameters)
  </code></pre>
  
  <p>Both work individually, My question how do I do both in one call?  I need to fold one into the other so I can make this in one HttpPost() call.</p>
