وب سرویس HttpUrlConnection (حل شده و مورد استفاده)

الان اینجوری درست شد با راهنمایی شما نصرتی جان : 

هر کسی دوست داره از این وب سرویس استفاده کنه برای API بالا تر از 22 !

 public class Webservice{

    public static String readUrl(String url,Map<String,String> params) {
        HttpURLConnection connect = null;
        try {

            //Create connection
            URL myLink = new URL(url);
            connect = (HttpURLConnection) myLink.openConnection();
            connect.setRequestMethod("GET");
            connect.setRequestMethod("POST");
            connect.setReadTimeout(10000);
            connect.setConnectTimeout(15000);
            connect.setDoInput(true);
            connect.setDoOutput(true);

            //Send request
            if (params != null) {

                String paramsString = getEncodedData(params);

                OutputStream os = connect.getOutputStream();
                BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
                writer.write(paramsString);
                writer.flush();
                writer.close();
                os.close();
            }

            //Get Response
            BufferedReader reader = new BufferedReader(new InputStreamReader(connect.getInputStream(), "UTF-8"));
            StringBuilder builder = new StringBuilder();
            String line = null;

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

            Log.i("LOG", " Data Line: " + builder.toString());

            reader.close();
            return builder.toString();

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

        } finally {
            if (connect != null) {
                connect.disconnect();
            }
        }
        return null;
    }

    // Get Encode Data
    private static String getEncodedData(Map<String,String> data) {
        StringBuilder sb = new StringBuilder();
        for (String key : data.keySet()) {
            String value = null;
            try {
                value = URLEncoder.encode(data.get(key), "UTF-8");
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            }

            if (sb.length() > 0)
                sb.append("&");

            sb.append(key + "=" + value);
        }
        return sb.toString();
    }
}


    این هم برای صدا زدن 

    String url = "http://192.168.1.1/login.php";
        
        Map<String,String> params = new HashMap<>();
        params.put("email", usertext.getText().toString());
        params.put("password", passtext.getText().toString());

        String result = Webservice.readUrl(url,params);
