private String getMimeTypeFromPath(String path) { 
    String extension = path; 
    int lastDot = extension.lastIndexOf('.'); 
    if (lastDot != -1) { 
        extension = extension.substring(lastDot + 1); 
    } 
    // Convert the URI string to lower case to ensure compatibility with MimeTypeMap (see CB-2185). 
    extension = extension.toLowerCase(Locale.getDefault()); 
    if (extension.equals("3ga")) { 
        return "audio/3gpp"; 
    } else if (extension.equals("js")) { 
        // Missing from the map :(. 
        return "text/javascript"; 
    } 
    return MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension); 
}
