    }

    @Override
    public void onPageFinished(WebView view, String url) {
        wb.loadUrl("javascript:window.HTMLOUT.processHTML('<head>'+document.getElementsByTagName('html')[0].innerHTML+'</head>');");
    }
};
wb = (WebView) findViewById(R.id.webview);
wb.getSettings().setJavaScriptEnabled(true);
wb.getSettings().setSupportZoom(true);
wb.getSettings().setBuiltInZoomControls(true);
wb.setWebViewClient(yourWebClient);
wb.loadUrl("http://pqrs.abcde.com/facebook");

Create the MyJavaScriptInterface class. And MyJavaScriptInterface for WebView.

    WebViewClient yourWebClient = new WebViewClient() {

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

        @Override
        public void onPageFinished(WebView view, String url) {
            wb.loadUrl("javascript:HtmlViewer.showHTML" +
                    "('<html>'+document.getElementsByTagName('html')[0].innerHTML+'</html>');");
        }
    };
    wb = (WebView) findViewById(R.id.webview);
    wb.getSettings().setJavaScriptEnabled(true);
    wb.getSettings().setSupportZoom(true);
    wb.getSettings().setBuiltInZoomControls(true);
    wb.setWebViewClient(yourWebClient);
    wb.loadUrl("http://pqrs.abcde.com/facebook");
    wb.addJavascriptInterface(new MyJavaScriptInterface(this), "HtmlViewer");

    class MyJavaScriptInterface {

    private Context ctx;
    MyJavaScriptInterface(Context ctx) {
        this.ctx = ctx;      
    }

    @JavascriptInterface
    public void showHTML(String html) {
        System.out.println(html);
    }

}

. wb.loadUrl( "javascript:..." );. @JavascriptInterface "public void showHTML".

showHtml (..) html-.

    webView.setWebViewClient(new myWebClient());
    webView.getSettings().setJavaScriptEnabled(true);
    webView.loadUrl(webdata);
}

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

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        // TODO Auto-generated method stub

        view.loadUrl(url);
        return true;

    }
}
