I’m trying to create a connection using localhost but is giving refused Connection

Question

public static String getJsonSystem(String urlString){

    HttpURLConnection urlConnection = null;
    BufferedReader reader = null;
    String retorno = "";

    try{
        URL url = new URL(urlString);
        urlConnection = (HttpURLConnection) url.openConnection();
        urlConnection.connect();

        InputStream in = new BufferedInputStream(urlConnection.getInputStream());

        reader = new BufferedReader(new InputStreamReader(in));
        String line = "";
        StringBuffer buffer = new StringBuffer();

        while ((line = reader.readLine()) != null){
            buffer.append(line);
        }

        retorno = buffer.toString();


    } catch (Exception e){
        e.printStackTrace();
    }


    return retorno;
}

Here as I call the connection:

String caminho = "http://192.168.0.11/system/pages/login";
HttpConnection conexão = new HttpConnection();
String resp = conexão.getJsonSystem(caminho);

AlertDialog.Builder alerta = new AlertDialog.Builder(this);
alerta.setMessage(resp);
alerta.show();

Answer 1

If you are using the emulator AVD you must use 10.0.2.2 to gain access to your computer’s localhost. As described in official documentation.

To the emulator Genymotion you must use 10.0.3.2.

--Edit

Remember to keep protocol http in the link, in your case:

"http://10.0.2.2/system/pages/login"
