This is the code that doesnt work. I found it online and i try to use it myself but the code of HTTP is always with an strok trough it and it doesnt work. i think its because its out dated but i have searched all over the internet and couldnt found an answer so i thought i might ask it here.
private class BackTask extends AsyncTask<Void,Void,Void> { ArrayList<String> list; protected void onPreExecute(){ super.onPreExecute(); list=new ArrayList<>(); } protected Void doInBackground(Void...params){ InputStream is=null; String result=""; try{ HttpClient httpclient=new DefaultHttpClient(); HttpPost httppost= new HttpPost("http://10.0.2.2:8080/getInterviewees.php"); HttpResponse response=httpclient.execute(httppost); HttpEntity entity = response.getEntity(); // Get our response as a String. is = entity.getContent(); }catch(IOException e){ e.printStackTrace(); } //convert response to string try{ BufferedReader reader = new BufferedReader(new InputStreamReader(is,"utf-8")); String line = null; while ((line = reader.readLine()) != null) { result+=line; } is.close(); //result=sb.toString(); }catch(Exception e){ e.printStackTrace(); } // parse json data try{ JSONArray jArray =new JSONArray(result); for(int i=0;i<jArray.length();i++){ JSONObject jsonObject=jArray.getJSONObject(i); // add interviewee name to arraylist list.add(jsonObject.getString("iname")); } } catch(JSONException e){ e.printStackTrace(); } return null; } protected void onPostExecute(Void result){ listItems.addAll(list); adapter.notifyDataSetChanged(); } }
