Second Web Service response still has the value of the first

The first thing I do in my application is to send a message to the server, just to test if the connection is up and running. When I receive "ok" from the server I continue the application.

On the next screen I have to show a list of names, so I make the list request. But it shows nothing the first time I start the screen, so that something appears I need to reload the screen, like when I turn the cell phone from portrait to landscape. It also appears if I put a button that forces the screen to be recreated.

After some tests I identified that the list was not showing up first because the content it was receiving was the "okay", which I get when doing the connection check. I also identified that the Log responsible for showing what is coming from the requests made (in the function attached below) was correct, showing that I received the list of names, but I also noticed that it is being shown after the Log that I put in the function that takes the function information below. How is this possible? I've called a function and put an object to get the return, however the object has a value set before the return of my function. And this set value is the value of my last request.

I'm using this library: compile org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2

  

Example: the initial request takes the right answer, hers. Because the > is the first, the list request that is the 2nd picks up the response of the 1st > requisition. If I reload the page this means that a new > request is made, right? That would be the requisition of the list. Now the list appears, > but it appears because it picked up the response from the 2nd requisition, which is also > a list. The response from the 3rd requisition was not used, and if I do a & quot; 4th requisition this will pick up information from the 3rd and so on.

Below is the code used to make the requisitions.

public class HttpConnection {
    public static String getSetDataWeb(String url, String method, String data) throws URISyntaxException {
        HttpClient httpClient = new DefaultHttpClient();
        HttpGet httpGet = new HttpGet(url);
        String answer = "";

        try{
            HttpClient httpclient = new DefaultHttpClient();
            HttpGet request = new HttpGet();
            // Setamos nossa URI
            request.setURI(new URI(url));
            // Executamos nossa transação HTTP
            HttpResponse response = httpclient.execute(request);
            // Pegamos o conteúdo advindo como resposta e inserimos em um InputStream
            answer = EntityUtils.toString(response.getEntity());
            Log.d("RESPOSTAhttp", answer);    
        }
        catch(NullPointerException e){ e.printStackTrace(); }
        catch(ClientProtocolException e){ e.printStackTrace(); }
        catch(IOException e){ e.printStackTrace(); }
        return(answer);
    }
}

Function that sends the requested URL to httpConnection

public static String comandaDetalhes(final String numCartao) throws SQLException {
        new Thread(){
            public void run(){
                try{
                    n = HttpConnection.getSetDataWeb("http://192.168.1.20:7070/comanda/detalhes/"+numCartao, "", "");
                } catch(Exception e) {

                }
            }
        }.start();

        return n;
    }

Function that requests the list of names for the function using httpConnection

public List<Conteudo> getComandaDetalhes(){
        conteudosL = new ArrayList<>();
        //--------INICIO PEGAR ComandaS---------
        if(chamadas == 0){
            try {
                String teste = ComandaDAO.comandaDetalhes(getIntent().getStringExtra("NumeroCartao"));
                Log.d("DETALHESCOMANDA", teste);
                if(teste != "Comanda inexistente!"){
                    JSONObject jo = new JSONObject(teste);
                    chamadas =0;
                    JSONArray jaBebidas = new JSONArray(jo.getString("bebidas"));
                    Log.d("RESPOSTADetalhesBebidas", String.valueOf(jaBebidas));
                    JSONArray jaPratos = new JSONArray(jo.getString("pratos"));
                    Log.d("RESPOSTADetalhesPratos", String.valueOf(jaPratos));
                    JSONArray jaComanda = new JSONArray(jo.getString("comanda"));
                    Log.d("RESPOSTADetalhesComanda", String.valueOf(jaComanda));

                    for(int i = 0; i<jaBebidas.length(); i++){
                        jo = jaBebidas.getJSONObject(i);
                        Conteudo conteudos = new Conteudo();
                        conteudos.setNome("x" + jo.getInt("quantidade_bebidas_comanda")
                                + "  " + jo.getString("nome_bebida") + "  R$ "
                                + jo.getDouble("preco_bebida"));
                        conteudosL.add(conteudos);
                    }
                    for(int i = 0; i<jaPratos.length(); i++){
                        jo = jaPratos.getJSONObject(i);
                        Conteudo conteudos = new Conteudo();
                        conteudos.setNome("x" + jo.getInt("quantidade_pratos_comanda")
                                + "  " + jo.getString("nome_prato") + "  R$ "
                                + jo.getDouble("preco_prato"));
                        Log.d("PratoAdicionado", conteudos.getNome());
                        conteudosL.add(conteudos);
                    }
                }
            } catch (SQLException e) {
                e.printStackTrace();
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
        return conteudosL;
    }
