title: How to send a POST request using volley with string body?
body: <p>I'm developing an Android app that communicate with a RESTful web service I wrote. Using <code>Volley</code> for <code>GET</code> methods is awesome and easy, but I can't put my finger on the <code>POST</code> methods.</p>
  
  <p>I want to send a <code>POST</code> request with a <code>String</code> in the body of the request, and retrieve the raw response of the web service (like <code>200 ok</code>, <code>500 server error</code>).</p>
  
  <p>All I could find is the <code>StringRequest</code> which doesn't allow to send with data (body), and also it bounds me to receive a parsed <code>String</code> response.
  I also came across <code>JsonObjectRequest</code> which accepts data (body) but retrieve a parsed <code>JSONObject</code> response.</p>
  
  <p>I decided to write my own implementation, but I cannot find a way to receive the raw response from the web service. How can I do it?</p>
