I have a URL, lets say for example www.example.com/movies/, which has the following JSON array:

    },
    {

You can get JSON Response from URL

    HttpClient client;
    String _responseMain = "";
    HttpResponse responseMain;


        AsyncTask<String, String, String> _Task = new AsyncTask<String, String, String>() {

            @Override
            protected void onPreExecute() {


            }

            @Override
            protected String doInBackground(String... arg0) 
            {

                if (NetworkAvailablity.checkNetworkStatus(CurrentActivity.this)) 
                {




                    try {
                        // Creating HTTP client
                        client = new DefaultHttpClient();

                        // Creating HTTP Post
                        HttpGet httpGet= new HttpGet("http://api.myjson.com/bins/44tys%22");




                        responseMain = client.execute(httpGet);
                        HttpEntity entitity = responseMain.getEntity();

                        _responseMain = EntityUtils.toString(entitity); // content will be consume only once
                System.out.println("Response : "+_responseMain);


                    } catch (UnsupportedEncodingException e) {
                        // writing error to Log
                        e.printStackTrace();

                    }
                    catch (Exception e) {
                        // TODO: handle exception
                        e.printStackTrace();


                    }


                } 
                else
                {

                }

                return null;

            }
            @Override
            protected void onPostExecute(String result) 
            {
                if (_responseMain!=null&&!_responseMain.equalsIgnoreCase("")) {
 try {
                            JSONArray _jArr = new JSONArray("YOUR_JSON_STRING");
                            HashMap<String, String> pairs = new HashMap<String, String>();
                            if (_jArr.length()>0) {

                                for (int i = 0; i < _jArr.length(); i++) {
                                    JSONObject _jObject = _jArr.getJSONObject(i);
                                    String _id = _jObject.getString("id");
                                    pairs.put("id", _id);

                                    String _director = _jObject.getString("director");
                                    pairs.put("director", _director);

                                    String _year = _jObject.getString("year");
                                    pairs.put("year", _year);

                                    String _image = _jObject.getString("image");
                                    pairs.put("image", _image);

                                    String _length = _jObject.getString("length");
                                    pairs.put("length", _length);

                                    String _stars = _jObject.getString("stars");
                                    pairs.put("stars", _stars);

                                    String _name = _jObject.getString("name");
                                    pairs.put("name", _name);

                                    String _description = _jObject.getString("description");
                                    pairs.put("description", _description);

                                    String _rating= _jObject.getString("rating");
                                    pairs.put("rating", _rating);

                                    String _url = _jObject.getString("url");
                                    pairs.put("url", _url);

                                }
                            }

                            }



                        } catch (JSONException e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }                   
}
                } else {

                }

            }
        };
        _Task.execute((String[]) null);

the leading underscore only makes the readability worse, imho — Arthur Eirich, Jun 23 '15 at 07:27
Thanks a lot for your response, Shoeb. But I have not saved the json file in my project. I have to fetch it from an URL. And I have to populate the values in a List. — Ram Kumar Krishnamurthy, Jun 23 '15 at 08:11
You can populate values in list, so you can use that String values which i have made. — Shoeb Siddique, Jun 23 '15 at 08:14
I have the code to convert the json array to a hashmap. I need a code to read the json code from this url "http://api.myjson.com/bins/44tys". This URL has my json code. — Ram Kumar Krishnamurthy, Jun 23 '15 at 11:23
