Had you seen this question? I suppose that you should use DownloadListener for file downloading:

WebView.setDownloadListener:

Registers the interface to be used when content can not be handled by the rendering engine, and should be downloaded instead. This will replace the current handler.

So, your code should look like this:

webview.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);
    }
});
