Alternative for deprecated HttpClient, HttpPost, NameValuePair

Question

I've been searching a lot, however haven't find any solution. I want to use URL, HttpsUrlConnection instead of deprecated ones (HttpClient, HttpPost, DefaultHttpClient). I have this code below so far:

Note "MyUrl" takes some parameters. See question 2.

 URL url = new URL("MyUrl");
    HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
    connection.setDoInput(true);
    connection.setDoOutput(true);
    connection.setRequestMethod("POST");

    /*Here exception occurs!*/
    connection.connect();

So, I have 2 problems to solve: (Maybe the 2nd one should be solved 1stly. I have no idea...)

1. When I use connection.someMethod(); SSLException occurs. (i.e connection.getResponseCode();)

The Error is :

javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x635cb550: Failure in SSL library, usually a protocol error

2. What is alternative way of List<NameValuePair> & BasicNameValuePair ? Those are deprecated as well.

Answer 1

You can use following library for HTTP requests-response

• http://loopj.com/android-async-http/
• http://square.github.io/okhttp/
• http://developer.android.com/training/volley/index.html

You can use Google-Gson for parsing JSON data

• https://github.com/google/gson

Answer 2

You don't need to use connect. Simply doing this:

 conn.setRequestMethod("POST");
 InputStream in = new BufferedInputStream(conn.getInputStream());
 response = org.apache.commons.io.IOUtils.toString(in, "UTF-8"); 

You will get your response.

Also, you can use ContentValues as a replacement for NameValuePair:

ContentValues initialValues = new ContentValues();
initialValues.put("parameter", value);
