Answer 1

Http client is deprecated in api level 22. So you must use open OpenUrlConnection. You can use this code

public class FetchUrl {

    private URL url;

    public String fetchUrl(String urlString, HashMap<String, String> values) {
        String response = "";
        try {
            url = new URL(urlString);
            Log.d("url string", urlString);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setReadTimeout(15000);
            conn.setConnectTimeout(15000);
            conn.setRequestMethod("POST");
            conn.setDoInput(true);
            conn.setDoOutput(true);

            OutputStream os = conn.getOutputStream();
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(
                    os, "UTF-8"));
            writer.write(getPostDataString(values));

            writer.flush();
            writer.close();
            os.close();
            int responseCode = conn.getResponseCode();

            if (responseCode == HttpsURLConnection.HTTP_OK) {
                String line;
                BufferedReader br = new BufferedReader(new InputStreamReader(
                        conn.getInputStream()));
                while ((line = br.readLine()) != null) {
                    response += line;
                }
            } else {
                response = "";

                throw new Exception(responseCode + "");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        return response;
    }

    private String getPostDataString(HashMap<String, String> params)
            throws UnsupportedEncodingException {
        StringBuilder result = new StringBuilder();
        boolean first = true;
        for (Map.Entry<String, String> entry : params.entrySet()) {
            if (first)
                first = false;
            else
                result.append("&");

            result.append(URLEncoder.encode(entry.getKey(), "UTF-8"));
            result.append("=");
            result.append(URLEncoder.encode(entry.getValue(), "UTF-8"));
        }
        Log.d("query string", result.toString());
        return result.toString();
    }

}

try below code

      HttpEntity httpEntity = httpResponse.getEntity();
  if (resEntity != null) {

  String response_From_Server = EntityUtils.toString(resEntity);
  Log.e("","response from server is : "+response_From_Server);
 }
