PHP $_POST data comes up empty Android

I am working on an Android app that reads an online PHP script and echos back a JSON array with different results. I am also sending POST variables from the app into the PHP script. When I post to the script from the website, it works fine and the POST data is present. When I post from the app, the POST data is empty.

private JSONArray addBusiness(String businessName, String businessCategory, String businessDescription) {
    String result = "";
    InputStream is = null;
    try {
        HttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost("http://somesite.com/testAndroid.php");

        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("id", "12345"));
        nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
        httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpClient.execute(httpPost);
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
    } catch (Exception e) {
        Log.e("log_tag", "Error in http connection " + e.toString());
    }

    try {
        Log.e("log_tag", "INSIDE TRY/CATCH");
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                is, "iso-8859-1"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        is.close();
        result = sb.toString();
        Log.e("log_tag", "RESULT: " + result);
    } catch (Exception e) {
        Log.e("log_tag", "Error converting result " + e.toString());
    }

    try {
        return new JSONArray(result);
    } catch (JSONException e) {
        Log.e("log_tag", "Error parsing data " + e.toString());
    }
    return null;
}

Here is the PHP code that comes up empty. Any ideas? Also, I use GoDaddy Shared Linux Hosting running PHP 5.2

<?php
$return = array();
$return['result'] = 'pooping for the Internet';
$return['business'] = 'BUSINESS';
$return['post'] = $_POST['id'];
echo '['.json_encode($return).']';
?>

All other $return data is correct except the 'post' return. Thoughts?
