Finishing Async Task throwing IO exception

My connection string has been working fine up until now and for some reason it keeps the responseData at -1 and throwing an IO exception

   private class GetBlogPostsTask extends AsyncTask<Object, Void, JSONObject>{

        @Override
        protected JSONObject doInBackground(Object... arg0) {//set verify and read the connection Async
            int responseCode = -1;
            JSONObject jsonResponse = null;

            try{
                URL blogUrl = new URL("http://blog.teamtreehouse.com/api/get_recent_summary/?count=" + NUMBER_OF_BLOG_POSTS);
                HttpURLConnection connection = (HttpURLConnection) blogUrl.openConnection();
                connection.connect();

                responseCode = connection.getResponseCode();

                if(responseCode == HttpURLConnection.HTTP_OK){
                    InputStream inputStream = connection.getInputStream();
                    Reader reader = new InputStreamReader(inputStream);
                    int contentLength = connection.getContentLength();
                    char[] charArray = new char[contentLength];
                    String responseData = new String(charArray);
                    reader.read(charArray);
                    jsonResponse = new JSONObject(responseData);

                }else{
                    Log.i(TAG, "Unsuccessful Code: " + responseCode);
                }
         }
            catch(MalformedURLException e){
                Log.e(TAG, "exception caught: ", e);
            }
            catch(IOException e){
                Log.e(TAG, "exception caught: ", e);
            }
            catch(Exception e){
                Log.e(TAG, "exception caught: ", e);
            }
            return jsonResponse;
        }

I got it. I guess the InputStreamReader.read() method is actually "reading"(saving) to the charArray and I was setting responseData to charArray before it had the input stream. I still dont know why i was getting that error but I moved the responseData line below the reader.read() call and it fixed it.
