Unable to connect websocket with wss in android

I am trying to connect with secure websocket connection wss:// in android using org.java_websocket.client.WebSocketClient API, but unable to connect with https. However it is working fine with ws://.. Here is my code.

private void connect(String websocketEndPointUrl) throws Exception {
    URI uri;
    try {

        websocketEndPointUrl="wss://echo.websocket.org:443";
        Log.i(TAG, " WSURL: " + websocketEndPointUrl);

        uri = new URI(websocketEndPointUrl);
    } catch (URISyntaxException e) {
        Log.e(TAG, e.getMessage());
        return;
    }

    mWebSocketClient = new WebSocketClient(uri,new Draft_17()) {
        @Override
        public void onOpen(ServerHandshake serverHandshake) {
            Log.i("Websocket", "Opened");
         }

        @Override
        public void onMessage(String s) {
            //final String message =s;

         }

        @Override
        public void onClose(int i, String s, boolean b) {
            Log.i("Websocket", "Closed " + s);
         }

        @Override
        public void onError(Exception e) {
            Log.i("Websocket", "Error " + e.getMessage());
         }
    };
    mWebSocketClient.connect();
}

i am using online test websocket url: ws://echo.websocket.org (port 80) // working with that wss://echo.websocket.org (port 443) As per my observation there is no need of certificate required in my code. Can anyone suggest me what is a reason and how i can fix this.

Find a solution. I don't know why this is not a part of the documentation. You just need to set setWebSocketFactory after WebSocketClient initialization and before the .connect() method

mWebSocketClient = new WebSocketClient(uri,new Draft_17()) 
{
    @Override
    public void onOpen(ServerHandshake serverHandshake) {
        Log.i("Websocket", "Opened");
    }

    @Override
    public void onMessage(String s) {
        //final String message =s;

    }

    @Override
    public void onClose(int i, String s, boolean b) {
        Log.i("Websocket", "Closed " + s);
    }

    @Override
    public void onError(Exception e) {
        Log.i("Websocket", "Error " + e.getMessage());
    }
};

if (websocketEndPointUrl.indexOf("wss") == 0) 
{
    try {
        SSLContext sslContext = SSLContext.getDefault();
        mWebSocketClient.setWebSocketFactory(new DefaultSSLWebSocketClientFactory(sslContext));
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
} 

mWebSocketClient.connect();
