  <p>I would like to get <strong>"pages"=>"files"</strong>, but return <code>org.json.JSONException: No value for files</code></p>
  
  <pre><code>JSONObject issueInfo = new JSONObject(filePath));
  JSONObject pages = issueInfo.getJSONObject("pages");
  Iterator iterator = pages.keys();
  
  while (iterator.hasNext()) {
      String key = (String) iterator.next();
      JSONObject page = pages.getJSONObject(key);
      JSONArray files = pages.getJSONArray("files");
      String _thumbUri = files.getString(1);
      String _graphicUri = files.getString(2);
      String _textUri = files.getString(3);
  }
