I read some about the error in google , i am bit new to php

org.json.JSONException: Value Record of type java.lang.String cannot be converted to JSONObject

This is my php

$sqlchk="SELECT STATUS FROM OBJECTS WHERE ID=$id";
$res = mysqli_query($con,$sqlchk);

$result = array();

while($row = mysqli_fetch_array($res)){
array_push($result,
array('ID'=>$row[0],
'STATUS'=>$row[1]
));
}


echo json_encode(array("result"=>$result));

this is my code java

try {
    try {
        responses = client.newCall(request).execute();
    } catch (IOException e) {
        e.printStackTrace();
    }
    String jsonData = responses.body().string();
    JSONObject Jobject = new JSONObject(jsonData);
    JSONArray Jarray = Jobject.getJSONArray("result");

    if (!responses.isSuccessful()) throw new IOException("Unexpected code " + responses);


    for (int i = 0; i < Jarray.length(); i++) {
        JSONObject object     = Jarray.getJSONObject(i);
        String    prize = object.getString("STATUS");
        System.out.println(prize);
    }
