Eclipse error message: String cannot be converted to JSONObject after laptop rebuild

HI

I get the following error when i attempt to log into my local emulator ever since i rebuilt my laptop (no code change has been made):

String cannot be converted to JSONObject

When i go into dubug mode in Eclipse the excetion gets caught here:

public JSONObject getJSONFromUrl(String url, List<NameValuePair> params) {

            // Making HTTP request
            try {
                  // defaultHttpClient
                  DefaultHttpClient httpClient = new DefaultHttpClient();
                  HttpPost httpPost = new HttpPost(url);
                  httpPost.setEntity(new UrlEncodedFormEntity(params));

                  HttpResponse httpResponse = httpClient.execute(httpPost);
                  HttpEntity httpEntity = httpResponse.getEntity();
                  is = httpEntity.getContent();

            } catch (UnsupportedEncodingException e) {
                  e.printStackTrace();
            } catch (ClientProtocolException e) {
                  e.printStackTrace();
            } catch (IOException e) {
                  e.printStackTrace();
            }

            try {
                  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();
                  json = sb.toString();
                  Log.e("JSON", json);
            } catch (Exception e) {
                  Log.e("Buffer Error", "Error converting result " + e.toString());
            }

I can see whatever string i enter being passed to the REST service a response returned and then validated throughout the login cycle.

It must be something environmental as it was working before i rebuilt laptop but once i set back up again on laptop with no code change made, the error started occurring.
Can anyone explain what it happening?

Note:
No change has been made to the REST service, java code or database prior to or after the rebuild

heres the DB_Functions PHP that gets called when hitting the logon button

<?php

class DB_Functions {

private $db;

//put your code here
// constructor
function __construct() {
require_once 'DB_Connect.php';
// connecting to database
$this->db = new DB_Connect();
$this->db->connect();
}

// destructor
function __destruct() {

}

/**

public function getUserByEmailAndPassword($email, $password) {
$result = mysql_query("SELECT * FROM users WHERE email = '$email'") or die(mysql_error());
// check for result
$no_of_rows = mysql_num_rows($result);
if ($no_of_rows > 0) {
$result = mysql_fetch_array($result);
$salt = $result['salt'];
$encrypted_password = $result['encrypted_password'];
$hash = $this->checkhashSSHA($salt, $password);
// check for password equality
if ($encrypted_password == $hash) {
// user authentication details are correct
return $result;
}
} else {
// user not found
return false;
}
}

// user existed
return true;
} else {
// user not existed
return false;
}
}

Your logger is not configured (or rather being called) in such a way as it shows the whole stack trace. It should be

Thanks for that.. and how do I configure the logger then?

CEHJ

Well i don't do Android. You need to find out how to get the logger to print a stack trace. Check the API docs

Eclipse has an error log Window > Show View > Error Log however when inspecting the log theres nothings bubbling up into the error log

It's nothing to do with Eclipse - read my last comment - carefully
