are you just making a website for a browser or any hybrid app ?

since it is a hybrid app add a listner to your webview

webView.setDownloadListener(new DownloadListener()
  {
   public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength)
   {
    //for downloading directly through download manager
    Request request = new Request(Uri.parse(url));
    request.allowScanningByMediaScanner();
    request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
    request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "download");
    DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
    dm.enqueue(request);
   }
  });

hybrid app ... install via google play store ... its not a website like m.mysite.com ... its an app that users download via google app store ... but i was build it with an online free app build service .. and in this you just need to use html and JavaScript .. – deva Apr 15 '16 at 10:44
for this you need to add a listner to a webview in android level. webview is a view where you are opening or rendering your html page in android. – Lucky Sharma Apr 15 '16 at 10:48
dear , thanks again , but as i describe that i dont know android coding and the site i use is providing me web interface where a app builder help me to build app . just like drag and drop and also i can insert html or javascript code .. but i dont have any option to add android code .. also i dont know how i can put android code in html file .. – deva Apr 15 '16 at 11:09
Dear but if you need to open or render any html page in your android view.. you need to open it in a webview, change reqired on html side is the same you have written , code needs to be added on android end – Lucky Sharma Apr 15 '16 at 11:16
