JSONException: End of input at character 0

Question

i am trying to get JSON values from server. I don\'t know what is wrong with my code. I am using AsyncTask and here is my code in doInBackground

Answer 1

The reason why you get this error is because you attempt to access the response more than once. For example lets lets say you do a log with the response, then create a json object with the same response object, it will trigger this one time acees error.

Answer 2

You are probably getting a blank response. Its not null but the jsontext is empty. So you are getting this error and not a Nullpointer exception

Are you sending right parameters to server.Also Check url respond to POST requests or not.

Answer 3

Check if the response is not empty before process the JSON:

if (response.success()) {
    if (response.getData() == null) {
        return null;
    } else if (response.getData().length() <= 0){
        return null;
    }

    try {
        // Logic
