                + "'    }); try{                        player.on(PreziPlayer.EVENT_STATUS, function(event) {           if (event.value == PreziPlayer.STATUS_CONTENT_READY) {                          var no_of_slides=player.getStepCount();             var user_sec="
                + 10
                + ";                var  new_sec=   user_sec/no_of_slides;                      setInterval('player.flyToNextStep();', (new_sec * 1000));           }       });     }catch(e){} </script></script>";

String mimeType = "text/html";
String encoding = "utf-8";
mainWebView.loadDataWithBaseURL("null",html, mimeType, encoding, "");   

private void initializeWebView()    
    {
        String newUA= "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.4) Gecko/20100101 Firefox/4.0";
        mainWebView = (WebView)findViewById(R.id.Wv);
        mainWebView.getSettings().setJavaScriptEnabled(true);
        mainWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
        mainWebView.getSettings().setDefaultZoom(ZoomDensity.FAR);
        mainWebView.getSettings().setAppCachePath( getApplicationContext().getCacheDir().getAbsolutePath() );
        mainWebView.getSettings().setAllowFileAccess( true );
        mainWebView.getSettings().setAppCacheEnabled( true );
        mainWebView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT );
