Downloading pdf through web browser and webview

Question

I am accessing a website which has .pdf documents. If I open that document through a web browser, it starts downloading it. If I open it through webview, nothing happens. What setting should I need to apply to webview to make it start downloading?

I already have this.

wvA.setDownloadListener(new DownloadListener()
{
    public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimeType,
                    long size)
    {
        Intent viewIntent = new Intent(Intent.ACTION_VIEW);
        viewIntent.setDataAndType(Uri.parse(url), mimeType);

        try
        {
            startActivity(viewIntent);
        }
        catch (ActivityNotFoundException ex)
        {
        }
    }
});

Thanks for replying. where should add "view.getContext().startActivity( new Intent(Intent.ACTION_VIEW, Uri.parse(url)));" ? — user200658, Jan 07 '13 at 17:53

Implement a download listener to handle any kind of download:

webView.loadUrl(uriPath);

webView.setDownloadListener(new DownloadListener() {
    @Override
    public void onDownloadStart(String url, String userAgent,
            String contentDisposition, String mimetype,
            long contentLength) {

        startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
    }
});

This is the a great answer. It's simple - this way you can let browser handle the downloading. But if you want to do it inside webview, you can also - you have the URL passed. – dorsz Mar 24 '16 at 08:43
You may find this example useful for downloading inside the app without starting a new activity and stay inside the application. https://www.mytrendin.com/downloading-file-android-webview/ – Alex Oct 22 '18 at 19:52

You should create WebViewClient and set it to your webview. Every time you click a link WebViewClient's shouldOverrideUrlLoading method will be called. Check that url points to pdf file and do what you want. For example, you can view pdf.

webView.setWebViewClient(new WebViewClient() {
    public boolean shouldOverrideUrlLoading (WebView view, String url) {
        if (url.endsWith(".pdf")) {
            startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
            // if want to download pdf manually create AsyncTask here
            // and download file
            return true;
        }
        return false;
    }
});
