Is it alright if I use 'org.apache.http.legacy' and continue using deprecated stuffs like NameValuePair and others?

Question

I am trying to integrate CCAvenue payment gateway onto my android application. For that, I downloaded their integration kit and used it. But, the kit that is available currently imports org.apache.http and uses its functionalities like httppost, namevaluepair, etc. So, my question is, as mentioned here, is it alright to make below mentioned changes in the gradle and continue using deprecated libraries?

android {
    useLibrary 'org.apache.http.legacy'
}

Put this code snippet in ServiceHandler class , you don''t need to use legacy. You can change their code as per your requirement those are just samples.

/**
 *
 * @param postUrl
 * @param postParams
 * @return response in string
 */
public static String makeServiceCall(final String postUrl, final Map<String, String> postParams) {
    Log.e("URL#",postUrl);
    StringBuilder responseBuilder  = new StringBuilder();
    HttpURLConnection conn = null;
    try {
        final URL mUrl = new URL(postUrl);
        conn = (HttpURLConnection) mUrl.openConnection();
        conn.setDoInput(true);
        conn.setDoOutput(true);
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        conn.setRequestProperty("charset", "utf-8");
        conn.setRequestProperty("User-Agent", "Mozilla/5.0 (Linux; U; Android-4.0.3; en-us; Galaxy Nexus Build/IML74K) AppleWebKit/535.7 (KHTML, like Gecko) CrMo/16.0.912.75 Mobile Safari/535.7");
        conn.connect();
        conn.setReadTimeout(180000);
        conn.setConnectTimeout(180000);
        final OutputStream os = conn.getOutputStream();
        BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
        writer.write(getQuery(postParams));
        writer.flush();
        writer.close();
        os.close();
        final int responseCode = conn.getResponseCode();
        if (responseCode == HttpsURLConnection.HTTP_OK) {
            String line;
            BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            while ((line = br.readLine()) != null) {
                responseBuilder.append(line);
            }
        } else {
            responseBuilder.append("");
        }
    } catch (MalformedURLException e) {
        e.printStackTrace();
        responseBuilder.append(e.getMessage());
        return responseBuilder.toString();
    } catch (IOException e) {
        e.printStackTrace();
        responseBuilder.append(e.getMessage());
        return responseBuilder.toString();
    } finally {
        if (null != conn) {
            conn.disconnect();
        }
    }
    System.gc();
    return responseBuilder.toString();
}


/**
 * @Param: map , takes in value in key val format
 */
private static String getQuery(final Map<String, String> mPostItems) throws UnsupportedEncodingException {
    final StringBuilder result = new StringBuilder();
    boolean first = true;
    final Set<String> mKeys = mPostItems.keySet();
    for (String key : mKeys) {
        if (first)
            first = false;
        else
            result.append("&");

        result.append(URLEncoder.encode(key, "UTF-8"));
        result.append("=");
        result.append(URLEncoder.encode(mPostItems.get(key), "UTF-8"));
        Log.e("Key#",key+"#"+mPostItems.get(key));
    }
    return result.toString();
}
