Getting 401.2 error in Android webviewclient

I am developing a mobile app to access a intranet site in android. SSL certificate of this website is fine. This I can say because when I open the site in android browser, it doesn't say that the certificate has a issue. Now I am using webviewclient to access the same site within my application, and the app throws a 401.2 error - You are not authorized to view this page. Kindly help me.

    package com.example.kms;

import android.app.Activity;
import android.graphics.Bitmap;
import android.net.http.SslCertificate;
import android.net.http.SslError;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.SslErrorHandler;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.webkit.CookieManager;

/*
 * Demo of creating an application to open any URL inside the application and clicking on any link from that URl
should not open Native browser but  that URL should open in the same screen.
 */
public class MainActivity extends Activity {
    /** Called when the activity is first created. */

    WebView web;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        web = (WebView) findViewById(R.id.webview01);
        web.setWebViewClient(new myWebClient());
        web.getSettings().setJavaScriptEnabled(true);
        web.loadUrl("https://kms.techmahindra.com");
    }

    public class myWebClient extends WebViewClient

Try to override onReceivedHttpAuthRequest() with in your WebViewClient like this:

 import android.webkit.HttpAuthHandler;

HttpAuthHandler

...

 @Override
    public void onReceivedHttpAuthRequest(WebView view,HttpAuthHandler handler, String host, String realm) {

        super.onReceivedHttpAuthRequest(view, handler, host, realm);

        view.setHttpAuthUsernamePassword(host, realm, username, password);

    }

See if this works for you.

If doesn't, you can try this as well :)
