MimeTypeMap fail to return extension for a filename that contains spaces

Question

I am trying to retrieve an extension from a file using MimeTypeMap.class of android.webkit package.

File file = new File(someUrl); 
String ext = MimeTypeMap.getSingleton()
.getFileExtensionFromUrl(file.getAbsolutePath());

ext returns null or empty if the file.getName() contains blank spaces!

How to solve it?

Answer 1

you can try

    public static String getMimeType(File file) {
            String extension = getExtension(file.getName());
            if (extension.length() > 0)
                return MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension.substring(1));

            return "application/octet-stream";
        }

public static String getExtension(String uri) {
        if (uri == null) {
            return null;
        }

        int dot = uri.lastIndexOf(".");
        if (dot >= 0) {
            return uri.substring(dot);
        } else {
            // No extension.
            return "";
        }
    }
