Sending string to php server

Question

I'm trying to send a string to php server from an app, the string should be sent (the method executes without an error), but the server isn't receiving anything. Here's what I'm doing, I followed another SO thread so I'm don't really know if what I'm doing is correct.

    protected String doInBackground(String... params) {

        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(url);

        try {
            StringEntity se = new StringEntity(data);
            httppost.setEntity(se);
            httpclient.execute(httppost);
        } catch (ClientProtocolException e) {
        } catch (IOException e) {
        }
        return null;
    }

Here's the code that sends the data to the server in a web app.

     function send_message( message ) {
        data =  "data";
        $.ajax({
          type: 'POST',
          url:"url",
          data: data,
          success: function() {
            $("#message_sent").val( "true" );
          },
          error: function(json) {
          },
          abort: function( json ) {
          }
        });
      }

So basically I want to translate the js code that sends the data into java code and use it in the app.

data is an object, needs to be something like data = {"str":"data"} — KellyCode

@kellycode data is a string in both the js code and my java code, I just stored it as a variable. — Annoynymoousrsa

For the love of all that is sacred, please, do not let your catch empty, at least do some Log.e(), otherwise you will never ever know if something is going wrong. — Logain

It was all with good intentions. Now you know that leaving a catch empty is generally a back practice, and for your own good you should add at least some logging. Probably that is all we need to figure out what went wrong with this code. Use developer.android.com/tools/debugging/debugging-log.html — Logain

This is a simple example of the send method:

function send_message(message) {
            var data = {"data":message};
            $.ajax({
                type: 'POST',
                url: "ret.php",
                data: data,
                success: function(returned) {
                    console.log(returned);
                },
                error: function(json) {
                     console.log(json);
                },
                abort: function(json) {
                }
            });
        }

And a simple example of the php in a file called ret.php in the same director as the html page:

<?php
$info = $_POST["data"];
echo $info;

Your success method will get the echo

You could call it with a button:

<button type="button" onclick="send_message('my message');"> Send it</button>

This is not what the user asks, he wants to make his code work on android, in java. The example in php is just to show us what he is trying to do.
