Android - WebView OnPageStarted, OnPageFinished & shouldOverrideUrlLoading not getting called

Question

I am developing an app in that when a user navigates from one link to another link I want to change the content of the edittext and want to show current url in the edittext.

But these 3 methods are not working, not even printing the logs. Here is the code.

    wv.setWebViewClient(new WebViewClient()
    {
        public boolean shouldOverrideUrlLoading(WebView view, String url)
        {               

            String url_new = view.getUrl();

            Log.v("","Webview URL: "+url);

            addressbar.setText(url_new);

            return false;                            
        }

        @Override
        public void onPageFinished(WebView view, String url)
        {
            // TODO Auto-generated method stub
            super.onPageFinished(view, url);

            String url_new = view.getUrl();                

            Log.v("","Webview Function URL: "+url_new);

            addressbar.setText(url_new);
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon)
        {
            // TODO Auto-generated method stub
            super.onPageStarted(view, url, favicon);

            String url_new = view.getUrl();             

            Log.v("","Webview Function URL: "+url_new);

            addressbar.setText(url_new);
        }
    }); 

wv is the WebView and addressbar is the EditText in above code.

What I am missing??

Please help..!!

You're overwriting your WebViewClient in your AsyncTask object:

 wv.setWebViewClient(new WebViewClient()); 

This overwrites your custom WebViewClient you set in Activity.onCreate().

You can probably get rid of the whole AsyncTask implementation, too. You can call loadUrl in a WebView in the UI thread with no problems. This might simplify things for you greatly.
