at response of type org.json.JSONObject cannot be converted to JSONArray

Question

I am trying to upload a file using HttpPost and send it to php where I would get a response in JsonArray . However the problem I am having is to use the JsonArray or object to use in android app. The information from the array will then be put in to SQLite db with in the app. I am unable to extract the data from array and getting the following error

"at response of type org.json.JSONObject cannot be converted to JSONArray" on JSONArray arr =object.getJSONArray("response");

I am not well verse with HttpPost and would appreciate any detail help I can get. I have tried few things from net but was not successful.

Array 
  ( 
     [response] => Array 
       ( 
           [Filepathserver] => webaddress 
           [email] => xyz@email.com
           [syncstatus] => yes 
       ) 

)  

java file

   String url = "uploadphpfile.php";
    File file = new File(filepath);
    try {

        HttpClient httpclient = new DefaultHttpClient();

        HttpPost httppost = new HttpPost(url);

         httppost.setEntity(mpEntity);
        Log.d("enitity",mpEntity.toString());

        HttpResponse response = httpclient.execute(httppost);
        HttpEntity r_entity = response.getEntity();

       String result = EntityUtils.toString(r_entity);
        JSONObject object = new JSONObject(result);

        JSONArray arr =object.getJSONArray("response");

        for (int i = 0; i < arr.length(); i++) {
            JSONObject obj = arr.getJSONObject(i);
            Log.d("filepathserver",obj.get("Filepathserver").toString());
        }
        //Do something with response...
        int statusCode = response.getStatusLine().getStatusCode();
        if (statusCode == 200) {
            // Server response
          String  responseString = EntityUtils.toString(r_entity);
        } else {
            String responseString = "Error occurred! Http Status Code: "
                    + statusCode;
        }
     } catch (Exception e) {
          Log.e(DBHelperReports.class.getName(), e.getLocalizedMessage(), 
  e);
     }
    }

php file

   $response = array();
  $response["Filepathserver"] = $target_path;
  $response["email"] = $target_path;
  $response["syncstatus"] = 'yes';
  echo json_encode(array("response"=>$response));

Answer 1

your php file produced a json object, not a json array.

so, try JSONObject arr =object.getJSONObject("response");

By the way, your logcat had already reminded you to treat it as a JSONObject.
