Android - Detect URL mime type?

Question

In my Android app, I have various URLs that I access from a database and then open a WebView to display that URL. Typically the url looks something like this:

Answer 1

You can find out what mime type of content in such way:

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

        //here you getting the String mimetype
        //and you can do with it whatever you want
    }
});

In this method you can check if mimetype is pdf and show it through Google Docs in WebView using modified url like this:

String pdfPrefixUrl = "https://docs.google.com/gview?embedded=true&url="

if ("application/pdf".equals(mimetype)) {
     String newUrl = pdfPrefixUrl + url;
     webView.loadUrl(newUrl);
}    

Hope it will help!
