org.json.JSON Exception : End of input at character 0

I'm trying to parse json from android but I get this strange exception. My json data is

{"id":"1","owner":"1","name":"gravitas","description":"is a fest","start_time":"0000-00-00 00:00:00","end_time":"0000-00-00 00:00:00","venue":"vellore","radius":"10","lat":"11","lng":"11","type":"type","ownername":"dilip","noofpolls":0,"noofquizes":0,"peopleattending":0,"result":true}

and in android I do 

JSONObject j =new JSONObject(response);
Event pst = gson.fromJson(j.toString(),  Event.class);

I get:

org.json.JSONException: end of input at character 0 of

What's wrong with it? Here is the code...

RestClient client = new RestClient("http://192.168.1.3/services/events/"+eve.getName());         
        try {
             Log.i("MY INFO", "calling boston");
            client.Execute(RequestMethod.POST);
        } catch (Exception e) {
            e.printStackTrace();
        }

        String response = client.getResponse();
         Log.i("MY INFO", response);
         GsonBuilder gsonb = new GsonBuilder();
         Gson gson = gsonb.create();
         Event pst = null;

        try {
            JSONObject j =new JSONObject(response);
            pst = gson.fromJson(j.toString(),  Event.class);

        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

In my case, i was referring to a function name, that didn't even exist.. Check the function name of your web service, after correcting the function name, it worked for me !

Oops! my bad I was supposed to use GET method.that url doesn't respond to POST requests so I was getting the org.json.JSON Exception : End of input at character 0.its because of this I got null response which generated that exception.

This error is also caused sometimes as json_encode function requires all incoming data to be UTF-8 encoded.

Try adding mysqli_set_charset($con, 'utf8'); into your php.

here is a snippet on how to parse using GSON

    Gson gson = new GsonBuilder().create();
    JsonParser jsonParser = new JsonParser();

     String response = client.getResponse();
    JsonObject jsonResp = jsonParser.parse(response).getAsJsonObject();
    // Important note: JsonObject is the one from GSON lib!
    // now you build as you like e.g.
    Event mEvent = gson.fromJson(jsonResp, Event.class);
