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 i

Answer 1

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.

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;
    }

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
