title: NameValuePair, HttpParams, HttpConnection Params deprecated on server request class for login app
body: <p>First time asking a question here, and new to android programming. I'm following an online youtube tutorial to create a login by user "Tonikami TV". Everything is fine with the app except when it comes to the serverRequests class. I get that <code>NameValuePair</code>, <code>HttpParams</code>, etc. are deprecated which I understand to be outdated and unsupported since API 22. I've searched for some fixed or alternatives but can't really make sense of them and how I would apply them to my code. Any help would be greatly appreciated. Thanks :)</p>
  
  <pre><code>    @Override
      protected Void doInBackground(Void... params) {
          ArrayList&lt;NameValuePair&gt; dataToSend = new ArrayList&lt;&gt;();
          dataToSend.add(new BasicNameValuePair("firstname", user.FirstName));
          dataToSend.add(new BasicNameValuePair("lastname", user.LastName));
          dataToSend.add(new BasicNameValuePair("age", user.Age + ""));
          dataToSend.add(new BasicNameValuePair("emailaddress", user.EmailAddress));
          dataToSend.add(new BasicNameValuePair("password", user.Password));
  
          //possible alternative code found on stack overflow don't know exactly what to do from here.
          ContentValues values= new ContentValues();
          values.put("firstname", user.FirstName);
          values.put("lastname", user.LastName);
          values.put("age", user.Age + "");
          values.put("emailaddress",user.EmailAddress);
          values.put("password",user.Password);
          //
  
          HttpParams httpRequestParams = new BasicHttpParams();
          HttpConnectionParams.setConnectionTimeout(httpRequestParams, CONNECTION_TIMEOUT);
          HttpConnectionParams.setSoTimeout(httpRequestParams, CONNECTION_TIMEOUT);
  
          HttpClient client = new DefaultHttpClient(httpRequestParams);
          HttpClient post = new HttpPost(SERVER_ADDRESS + "Register.php");
  
          try{
              post.setEntity(new URLEncoderFormEntity(dataToSend));
              client.execute(post);
          }catch (Exception e){
              e.printStackTrace();
          }

  <p>Here is the entire code in the ServerRequests class. Apologies if its rather long.</p>
