Hello ppl i have created one android application using android webview. In the url that i have loaded in webview has print options in some place.

 

java code

WebSettings webSetting = webView.getSettings();
        webSetting.setBuiltInZoomControls(true);
        webSetting.setJavaScriptEnabled(true);
        
        webView.addJavascriptInterface(new webAppInterface(this), "Android");
        
        
        
        webView.setWebChromeClient(new WebChromeClient());
        
        webView.getSettings().setLoadsImagesAutomatically(true);
        webView.setWebViewClient(new WebViewClient());
        webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    
        webView.setWebViewClient(new WebViewClient() {
            @Override
           public void onPageStarted(WebView view, String url, Bitmap favion){
               super.onPageStarted(view,url,favion);
               setProgressBarVisibility(View.VISIBLE);
           }
           @Override
           public void onPageFinished(final WebView view, String url) {
               //hide loading image
            
               //hide progressbar
               setProgressBarVisibility(View.GONE);
               //show webview
             
              // doWebViewPrint();
            }
       });
        if(cm != null && cm.getActiveNetworkInfo() != null && cm.getActiveNetworkInfo().isConnected()){
            webView.loadUrl("://site/");
            webView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
            webView.setWebViewClient(new MyBrowser(){ public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {  
                  webView.getSettings().setAllowFileAccess(true);
             
               webView.loadUrl("file:///android_asset/first.html");
     
       }  });
           
        }
        else{
           
            webView.getSettings().setAllowFileAccess(true);
            webView.loadUrl("file:///android_asset/first.html");
            webView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
        }
        registerReceiver(broadcastReceiver, new IntentFilter("INTERNET_LOST"));
       
    }

Asp.net Javascript

 <script language="javascript" type="text/javascript">
         function PrintPage3() {
             var printContent = document.getElementById('<%= noder.ClientID %>');
             var printWindow = window.open("All Records", "Print Panel", 'left=50000,top=50000,width=120%,height=0');
             printWindow.document.write(printContent.innerHTML);
             printWindow.document.close();
             printWindow.focus();
             printWindow.print();
         }
         
    </script>

 

when html button is click, the webview display  Server Error 404- File or directory not found.

but when i visited the site from google chrome it works fine.
