  <pre><code>String url = "http://192.168.1.23/ws/svn/branches/application/public/connectMobile";
                      try {
  
  
                          JsonObject json = new JsonObject();
                          json.addProperty("email", email.getText().toString());
                          json.addProperty("psw", password.getText().toString());
                          Log.i("json envoyé",json.toString());
  
  
  
                              Ion.with(context)
                                      .load("POST",url)

  <p>I suspect that the parse error is due to the fact that nothing is returned.</p>
  
  <p>Moreover, on my server, I wrote a piece of code to check what's coming in, and I receive nothing on the server from my sample but when trying with RESTEASY with firefox sending the same, the post is correctly sent my server receives the post and a response is sent back.</p>
  
  <p>Any idea ? I can't figure out what's wrong...</p>
