Show Progress using ProgressBar for WebViewClient


I am using WebViewClient to load web pages and I would like to show progress bar for my code. My code isn't loading the progress gradually. It only shows 100% progress. How do I set the progress based on web page loading time?

For my purpose I have to load just "https://www.google.com" on a WebView only. Please help. Thank you. Code is shown below :

Activity file

public class MainActivity extends Activity {

private WebView webView;
private ProgressBar progressBar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    int vc = Color.parseColor("#feca01");


    progressBar = (ProgressBar) findViewById(R.id.determinateBar);
    progressBar.getProgressDrawable().setColorFilter(
            vc, android.graphics.PorterDuff.Mode.SRC_IN);
    webView = (WebView) findViewById(R.id.webView);
    webView.setWebViewClient(new MyBrowser());
    webView.getSettings().setJavaScriptEnabled(true);
    webView.loadUrl("http://deelay.me/5000/http://www.google.com");

}

private class MyBrowser extends WebViewClient {

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon)
    {
        super.onPageStarted(view, url, favicon);
        progressBar.setVisibility(View.VISIBLE);
        progressBar.incrementProgressBy(10);

    }

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);
        progressBar.setVisibility(View.VISIBLE);
       // progressBar.setProgress(0);
    }
 }

}

XML file

`

<ProgressBar
    android:id="@+id/determinateBar"
    style="@android:style/Widget.ProgressBar.Horizontal"
    android:layout_width="400dp"
    android:padding="0dp"
    android:layout_height="2dp" />

<WebView
    android:layout_height="match_parent"
    android:id="@+id/webView"
    android:layout_weight="0.91"
    android:layout_width="match_parent"
    android:padding="0dp"
    />

            }

            public void onPageFinished(WebView view, String url) {
    
                progressBar.setVisibility(View.GONE);
            }
