Tried to find in other answers, but still can't make it:

class GetUpdate extends AsyncTask<Void, Void, Void>{

    JSONObject jobj = null;

    @Override
    protected Void doInBackground(Void... params) {             

        //JSON
        JSONParser jparser = new JSONParser();
        JSONObject data = jparser.getJSONFromUrl("http://myserver.com/file.txt");                       

        String title2 = "";

        try {
            jobj = data.getJSONObject("party1");                
            title2 = jobj.getString("title");
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        //title = new String[] { title2,title2,title2,title2};
        Log.i("ABCDE", "Got the address: " + title2);

        return null;
    }

}

and here is the JSON that it get from with JSONParser.java (JSON - single file to use with android app):

    {
   "party1": {
      "title": "Screen no. 1",
      "address": "Sesame Street",
      "date": "01-01-2014",
      "image": "http://myserver.com/image.jpg",
      "destination": "somewhere"
   },
   "party2": {
      "title": "Screen no. 2",
      "address": "Oak Street",
      "date": "01-01-2014",
      "image": "http://myserver.com/image.jpg",
      "destination": "somewhere"
   }
}

Anyone can spot the problem?

    I can't believe I didn't notice the .txt file suffix... No, plain text can't be used to store json objects. If the file were in JSON format (.json) this should work, the nicely formatted output that you tend to see json in is a product of printing functions Commented Dec 14, 2014 at 23:55
