Android WebView download not working

Question

I have created one web view having page containing html form and on submitting form (with post method) it should download the file.

I have implemented webview download listener so i can handle downloads.

@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.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
    request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "DownloadFile.pdf");
    DownloadManager dm = (DownloadManager) getContext().getSystemService(Activity.DOWNLOAD_SERVICE);
    dm.enqueue(request);
}

Now problem is, If i use post method in HTML FORM in page, download not working(it is working if i use GET method)

in chrome mobile app it's works with post method, but it is not working in android web view.

Answer 1

Unfortunately DownloadManager doesn't support POST method. Please find the corresponding issues 3949 and 1780.

You will have to use alternative means to download the file in your application.
