Parsing JSON from url with exception: Error parsing data org.json.JSONException: Unterminated array at character 115

Question

I'm parsing this url and I've got an exception and don't know how to skip it over... I need to get only names of 100 the most popular apps. There is key "im:name" and inside of it key "lebel", but as I see it is invalid JsonArray, so I need to find the way to get names by the key "im:name"... has smb any ideas how can I fix this?

This is my AsyncTask.class

    public class AsyncTaskParseJson extends AsyncTask<String, String, String> {

    String jsonStringUrl = "https://itunes.apple.com/br/rss/topfreeapplications/limit=100/json";
    JSONArray dataJsonArr = null;

    @Override
    protected void onPreExecute() {}

    @Override
    protected String doInBackground(String... arg0) {

        try {
            // instantiate our json parser
            JsonParser jParser = new JsonParser();
            // get json string from url
            JSONObject json = jParser.getJSONFromUrl(jsonStringUrl);
            // get the array of users
//HERE I NEED TO CHANGE SOMETHING
            dataJsonArr = json.getJSONArray("feed"); // probably wrong
            // loop through all users
            for (int i = 0; i < dataJsonArr.length(); i++) {
                JSONObject c = dataJsonArr.getJSONObject(i);
                // Storing each json item in variable
                String name = c.getString("im:name");//probably wrong
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return null;
    }
}

and this is the log

Will be very very thanksful for the help!! Cuz I'm really stack(

Seems like a JSON formating error stackoverflow.com/questions/10334385/… im not sure tho sorry — TehCoder
– TehCoder, Commented Sep 10, 2014 at 17:11
@TehCoder , yes, it is kinda like that, but I have to solve it. I can't make this JsonArray correct, because this is url... I need to skip it over and search there only for "im:name"... — Yurets
– Yurets, Commented Sep 10, 2014 at 17:14
@meda, I haven't it, unfortunately, and this is a small app, so no needs... — Yurets
– Yurets, Commented Sep 10, 2014 at 17:22
@meda, I gonna try it, I just thought must be much easier way... like "search in json's keys" or something... — Yurets
– Yurets, Commented Sep 10, 2014 at 17:28
I would recommend you replace JSONObject json = jParser.getJSONFromUrl(jsonStringUrl); with JSONObject json = new JSONObject(EntityUtils.toString(new DefaultHttpClient().execute(new HttpGet(jsonStringUrl)).getEntity())); and stop using that JsonParser entirely — njzk2

First You make a call get the result into a string called json. Then You have to convert the string into Json object

          String json = null;  
        JSONObject jsonObj = null;  JSONObject feedsObject = null;


     json = jParser.getJSONFromUrl(jsonStringUrl);
       if (json != null) {
    try {
         jsonObj = new JSONObject(json);

        feedObject = jsonObj.getJSONObject("feed");

For a better understanding visit http://json.parser.online.fr/beta/ and paste your json data there. On the right you have a settings button---> show types You can find what are objects, strings and arrays

See the image below. You were trying get a an object not an array

unrelated to the question

Indra Kumar S Over a year ago

njzk2 He is trying to get an object called feeds. But In his code, He wrote......... dataJsonArr = json.getJSONArray("feed"); // probably wrong ........... It should be corrected or not?

njzk2 Over a year ago

the error is related to the fact that JsonParser returns null because the part that reads the data from the network is broken

Yurets Over a year ago

@njzk2, yes, you got that correctly! I've checked this json is invalid.. do you know the way how I just can get those names in the most easier way according to code I've already wrote? and I changed encoding already, thanks!

@Yurets: see my comments under the question. The networking part is the issue. I have posted in comment a much shorter way of obtaining the json object.

You are not accessing the values the right way, check this:

JsonParser jParser = new JsonParser();
JSONObject json = jParser.getJSONFromUrl(jsonStringUrl);
JSONObject feeds = json.getJSONObject("feed");

dataJsonArr = feeds.getJSONArray("entry");
for (int i = 0; i < dataJsonArr.length(); i++) {
    JSONObject c = dataJsonArr.getJSONObject(i);
    String name = c.getString("im:name");
    Log.d("mylog", "name = " + name);
}

You probably want to append this data into an array list, otherwise you would be overwriting these variables.

Please note org.json is a limited library i have personally experienced its limitation when the json data is too large.

I suggest you to ditch it and use GSON or jackson which are fare more advanced.

Impossible, which line

njzk2 Over a year ago

irrelevant to the question

meda Over a year ago

@njzk2 and so is your comment irelevant to my answer

meda Over a year ago

@Yurets if you cannot log the full json it means you need to switch the library

Yurets Over a year ago

@meda, it seems like yeah... thank you for your efforts! I appreciate your time, honestly!

Thanks to njzk2 for the advice to avoid using JSONParser, so I've made all I needed in very shorter time and with less efforts. I needed to get root JSONObject - names of applications in iTunes. and insert it into database. This is the full code of the method doInBackground in AsyncTask.class

@Override
    protected Boolean doInBackground(Void... params) {
        Log.d(LOG, "AsyncTask. Do in background");
        ContentValues cv = new ContentValues();

        try {//Making a request to server getting entities
            JSONObject json = new JSONObject(EntityUtils.toString(
                    new DefaultHttpClient().execute(
                            new HttpGet(url)).getEntity()));
            //getting json root object
            JSONObject feedObject = json.getJSONObject("feed");
            //getting needed array in root json object
            JSONArray entryArray = feedObject.getJSONArray("entry");

            //moving though the array
            for(int i = 0; i < entryArray.length(); i++){
                //getting all objects in array
                JSONObject entryObjects = entryArray.getJSONObject(i);
                //taking objects with needed key
                JSONObject nameObject = entryObjects.getJSONObject("im:name");
                //getting string name
                String name = nameObject.getString("label");
                //putting data into ContentValues - name and id (for making a numbers
                // next to records in ListView)
                cv.put(DB.COL_NAME, name);
                cv.put(DB.COL_ID, i+1);
                mDB.insert(cv);
                //just controlling in log
                Log.d(LOG, "" + name);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return true;
    }
