JSONArray cannot be converted to JSONObject - php

Question

I get following error:
Error parsing data org.json.JSONException: Value [] of type org.json.JSONArray cannot be converted to JSONObject
Here is the Android and PHP code I have:
private void eventUpdatePoint(String eventStatus,int lat,int lon){
JSONParser jsonParserEUP = new JSONParser();
try
{
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("longtitude", Integer.toString(lon)));
params.add(new BasicNameValuePair("latitude", Integer.toString(lat)));
params.add(new BasicNameValuePair("eventstatus", eventStatus));
String url_updatePoint = "http://10.0.2.2/android_connect/event_update_point.php";
JSONObject json = jsonParserEUP.makeHttpRequest(url_updatePoint,"POST", params);
Log.d("Response", json.toString());
}
catch(Exception e)
{
e.printStackTrace();
Log.d("ERROR:","ERROR:" + e.getClass().getName() + ":" + e.getMessage());
}
}
php code:
$response = array(); if (isset($_POST['longtitude']) && isset($_POST['latitude']) &&isset($_POST['eventstatus'])) {
$longtitude = $_POST['longtitude'];
$latitude = $_POST['latitude'];
$eventstatus = $_POST['eventstatus'];
$e_id=0;
$score=0;
require_once __DIR__ . '/db_connect.php';
$db = new DB_CONNECT();
$result = mysql_query("SELECT id FROM cordinates WHERE longtitude=$longtitude AND latitude=$latitude") or die(mysql_error());
while ($row = mysql_fetch_array($result)) {
$e_id = $row["id"];
}
$result = mysql_query("SELECT score FROM point WHERE e_id=$e_id") or die(mysql_error());
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_array($result)) {
$score = $row["score"];
}
if($eventstatus=="inc")
{
$score+=10;
$result = mysql_query("UPDATE point SET score=$score where e_id=$e_id") or die(mysql_error());
$response["success"] = 1;
$response["message"] ="Score point increased";
}
else if($eventstatus=="dec")
{
$score-=10;
$result = mysql_query("UPDATE point SET score=$score where e_id=$e_id") or die(mysql_error());
$response["success"] = 0;
$response["message"] ="Score point decreased";
}
}
echo json_encode($response);
What am I doing wrong?

Answer 1

The webservice you are using returns a JSONArray. You have to use an object of type JSONArray to store it. You can't use a JSONObject.
Change this line:
JSONObject json = jsonParserEUP.makeHttpRequest(url_updatePoint,"POST", params);
...to this:
JSONArray json = jsonParserEUP.makeHttpRequest(url_updatePoint,"POST", params);

Answer 2

Log your response.If it starts with"[" and ends with "]",you have to store it in variable of type "JSONArray".With attention to your log,your response must be a "JSONArray",so simply save your response in a variable of type "JSONArray".
