Parsing JSON object from String in Android : I am trying to parse the json object from the data at the end of the post using the following code but I seem to have problem converting the intial string to JSON and also extracting JSON object in the key values of "feed" and "entry".

    protected void JSONparse(String result) {
        //parse JSON data
        try {
            JSONObject reader = new JSONObject(result);
            JSONObject head = reader.getJSONObject("feed").getJSONObject("entry").getJSONObject(result);
            JSONArray jArray = new JSONArray(head);
            for(int i=0; i < jArray.length(); i++) {
                JSONObject jObject = jArray.getJSONObject(i);
                String name = jObject.getString("name");
                String location = jObject.getString("location");
                String contact = jObject.getString("contact");
                Toast toast = Toast.makeText(this, name+" "+location+" "+contact, Toast.LENGTH_SHORT);
                toast.show();
    
            } // End Loop
    
        } catch (JSONException e) {
            Log.e("JSONException", "Error: " + e.toString());
        } // catch (JSONException e)
    
    }
