essayer ici le code ci-dessous

@Override 
      public boolean shouldOverrideUrlLoading(WebView view, String url) { 
        // handle different requests for different type of files 
        // this example handles downloads requests for .apk and .mp3 files 
        // everything else the webview can handle normally 
        if (url.endsWith(".apk")) { //change .apk to any format you want to download 
         Uri source = Uri.parse(url); 
         // Make a new request pointing to the .apk url 
         DownloadManager.Request request = new DownloadManager.Request(source); 
         // appears the same in Notification bar while downloading 
         request.setDescription("Description for the DownloadManager Bar"); 
         request.setTitle("YourApp.apk"); 
         if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) { 
          request.allowScanningByMediaScanner(); 
          request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED); 
         } 
         // save the file in the "Downloads" folder of SDCARD 
         request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "SmartPigs.apk"); 
         // get download service and enqueue file 
         DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE); 
         manager.enqueue(request); 
        } 
        else if(url.endsWith(".mp3")) { 
         // if the link points to an .mp3 resource do something else 
        } 
        // if there is a link to anything else than .apk or .mp3 load the URL in the webview 
        else view.loadUrl(url); 
        return true;     
      } 

Hope this helps
