Bug in the reader method...Please advise

Question

I am using android studio to program this app and discovered the reader that reads in the inputStream is converting the data incorrectly for some reason. When I go into debug mode and check my item count and pages, they are displaying the incorrect results.

here is my debug window for the content length: reader = {java.io.InputStreamReader@831727394904} contentLength = 3034

Here is my CharArray debug window (you can see the count being displayed 10 instead of 20, same goes for the pages): charArray = {char[3034]@831727410376} [0] = '{' 123 [1] = '"' 34 [2] = 's' 115 [3] = 't' 116 [4] = 'a' 97 [5] = 't' 116 [6] = 'u' 117 [7] = 's' 115 [8] = '"' 34 [9] = ':' 58 [10] = '"' 34 [11] = 'o' 111 [12] = 'k' 107 [13] = '"' 34 [14] = ',' 44 [15] = '"' 34 [16] = 'c' 99 [17] = 'o' 111 [18] = 'u' 117 [19] = 'n' 110 [20] = 't' 116 [21] = '"' 34 [22] = ':' 58 [23] = '1' 49 [24] = '0' 48 [25] = ',' 44 [26] = '"' 34 [27] = 'c' 99 [28] = 'o' 111 [29] = 'u' 117 [30] = 'n' 110 [31] = 't' 116 [32] = '_' 95 [33] = 't' 116 [34] = 'o' 111 [35] = 't' 116 [36] = 'a' 97 [37] = 'l' 108 [38] = '"' 34 [39] = ':' 58 [40] = '1' 49 [41] = '8' 56 [42] = '4' 52 [43] = '7' 55 [44] = ',' 44 [45] = '"' 34 [46] = 'p' 112 [47] = 'a' 97 [48] = 'g' 103 [49] = 'e' 101 [50] = 's' 115 [51] = '"' 34 [52] = ':' 58 [53] = '1' 49 [54] = '8' 56 [55] = '5' 53 [56] = ',' 44 [57] = '"' 34 [58] = 'p' 112 [59] = 'o' 111 [60] = 's' 115 [61] = 't' 116 [62] = 's' 115

Here is my code: private class GetBlogPostsTask extends AsyncTask <Object, Void, String> {

    @Override
    protected String doInBackground(Object[] objects) {

        int responseCode = -1;
        try {

            URL blogFeedUrl = new URL("http://blog.teamtreehouse.com/api/get_recent_summary/?count=" + NUMBER_OF_POSTS);
            HttpURLConnection connection = (HttpURLConnection)blogFeedUrl.openConnection();
            connection.connect();
            responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK){
                InputStream inputStream = connection.getInputStream(); //store the data into the input stream
                Reader reader = new InputStreamReader(inputStream); //read the input stream
                int contentLength = connection.getContentLength(); //get the number of characters to read in
                char[] charArray = new char[contentLength];  //create the char array to store the the data
                reader.read(charArray); //read and store the data array into the char array
                String responseData = new String(charArray); //create a new string and convert and store from char to string

                //get the string data
                JSONObject jsonResponse = new JSONObject(responseData);
                String status = jsonResponse.getString("status");


                JSONArray jsonPosts = jsonResponse.getJSONArray("posts");
                for(int i = 0; i < jsonPosts.length(); i++){
                    JSONObject jsonPost = jsonPosts.getJSONObject(i);
                    String title = jsonPost.getString("title");
                    Log.v(TAG, "Post " + i + ": " + title);

                }

Can you please advise?
