my code which i have successfully parse 1st json array "data" and objects:

try {
        File yourFile = new File(Environment.getExternalStorageDirectory(), "textarabics.txt");
        FileInputStream stream = new FileInputStream(yourFile);
        String jsonStr = null;
        try {
            FileChannel fc = stream.getChannel();
            MappedByteBuffer bb = fc.map(FileChannel.MapMode.READ_ONLY, 0, fc.size());

            jsonStr = Charset.forName("UTF-8").decode(bb).toString();
            Log.d("Noga Store", "jString = " + jsonStr);
          }
          finally {
            stream.close();
          }

             Log.d("Noga Store", "jString = " + jsonStr);
                     // A JSONTokener is needed in order to use JSONObject correctly
             JSONTokener jsonTokener = new JSONTokener(jsonStr);
                     // Pass a JSONTokener to the JSONObject constructor
             JSONObject jsonObj = new JSONObject(jsonTokener);


            // Getting data JSON Array nodes
            JSONArray data  = jsonObj.getJSONArray("data");

            // looping through All nodes
            for (int i = 0; i < data.length(); i++) {
                JSONObject c = data.getJSONObject(i);

                String id = c.getString("id");
                String title = c.getString("title");
             //   String duration = c.getString("duration");
                int duration = c.getInt("duration");

                // tmp hashmap for single node
               /* HashMap<String, String> parsedData = new HashMap<String, String>();

                // adding each child node to HashMap key => value
                parsedData.put("id", id);
                parsedData.put("title", title);
                parsedData.put("duration", duration);*/

                textnames.add(title);
                textduration.add(duration);
            //    textnames.add(duration);
                // do what do you want on your interface
              }


       } catch (Exception e) {
       e.printStackTrace();
      }

Answer 1

You can do same as you did for "data" json array

for example

JSONArray videos = jsonObj.getJSONArray("videos");
JSONArray images = jsonObj.getJSONArray("images");
