how to parse json archive dot org

Question

Hope my below code will help you to parse your json:

/** An async task to prepare target image mapping list. */
    private class PrepareMapTask extends AsyncTask<String, Integer, Boolean>
    {
        // Initialize with invalid value
        private int mPrepareResult = -1;
        private String mJsonString = null;

        protected Boolean doInBackground(String... urls)
        {
            mJsonString = downloadFileFromInternet(urls[0]);
            if(mJsonString == null /*|| mJsonString.isEmpty()*/)
                return false;

            JSONObject jObject = null;
            try {
                jObject = new JSONObject(mJsonString);
                JSONArray jsonImageArray = jObject.getJSONArray("imageTarget");
                JSONArray jsonUrlArray = jObject.getJSONArray("videoUrls");
                JSONArray jsonVideoOrUrlArray = jObject.getJSONArray("videoOrUrl");
                if (jsonImageArray == null || jsonUrlArray == null)
                    return false;
                for (int i = 0; i<jsonImageArray.length(); i++){ 
                    mapTargetUrl.put(jsonImageArray.get(i).toString(), jsonUrlArray.get(i).toString());
                    mVideoOrUrl.add(jsonVideoOrUrlArray.get(i).toString());
                }
            } catch (JSONException e) {
                e.printStackTrace();
                return false;
            }

            return true;
        }

        protected void onPostExecute(Boolean result)
        {
        }

        private String downloadFileFromInternet(String url)
        {
            if(url == null /*|| url.isEmpty() == true*/)
                new IllegalArgumentException("url is empty/null");
            StringBuilder sb = new StringBuilder();
            InputStream inStream = null;
            try
            {
                url = urlEncode(url);
                URL link = new URL(url);
                inStream = link.openStream();
                int i;
                int total = 0;
                byte[] buffer = new byte[8 * 1024];
                while((i=inStream.read(buffer)) != -1)
                {
                    if(total >= (1024 * 1024))
                    {
                        return "";
                    }
                    total += i;
                    sb.append(new String(buffer,0,i));
                }
            }catch(Exception e )
            {
                e.printStackTrace();
                return null;
            }catch(OutOfMemoryError e)
            {
                e.printStackTrace();
                return null;
            }
            return sb.toString();
        }

        private String urlEncode(String url)
        {
            if(url == null /*|| url.isEmpty() == true*/)
                return null;
            url = url.replace("[","");
            url = url.replace("]","");
            url = url.replaceAll(" ","%20");
            return url;
        }

    }

My Json:

{
        "imageTarget": [
        "image1",
        "image2",

    ],
        "videoUrls": [
        "http://www.youtube.com/watch?v=QoZRHLmUKtM",
        "http://ar.qualcomm.at"
    ],
        "videoOrUrl": [
        "video",
        "url"

    ]
}
