Webview download file

Question

I am opening a webpage inside android webview. After filling the information on the webpage there is a button to download file. But the file is not downloading. I have a confusion regarding which url to pass to the download task . Clinking on the button should download a pdf file. But it does not do anything

mWebView.setDownloadListener(new DownloadListener() {
            @Override
            public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength) {
                DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
                request.allowScanningByMediaScanner();
                request.setMimeType(mimetype);
                //------------------------COOKIE!!------------------------
                String cookies = CookieManager.getInstance().getCookie(url);
                request.addRequestHeader("cookie", cookies);
                request.addRequestHeader("User-Agent", userAgent);
                request.setDescription("Downloading file...");

                request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS,URLUtil.guessFileName(url, contentDisposition, mimetype));
                request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
                DownloadManager dm = (DownloadManager)getSystemService(DOWNLOAD_SERVICE);
                dm.enqueue(request);


            }
        });

have you set correct permissions? Share your manifest file and put logger inside your code and share logs — Amod Gokhale, May 04 '17 at 10:36

does it give any error in log? refer to this link http://stackoverflow.com/questions/10069050/download-file-inside-webview — Amod Gokhale, May 04 '17 at 10:42
Please explain the url that we pass to the download listener, because when we click on a download button inside the opened page that is a different url — Paras Watts, May 04 '17 at 10:48
it does not give any error, the download button goes into inactive state after clicking on download — Paras Watts, May 04 '17 at 10:49

Have you tried this ?

mWebView.setDownloadListener(new DownloadListener() {
public void onDownloadStart(String url, String userAgent,
            String contentDisposition, String mimetype,
            long contentLength) {
    Intent i = new Intent(Intent.ACTION_VIEW);
    i.setData(Uri.parse(url));
    startActivity(i);
}

});
