byte[] content = ;
InputStream is = new BufferedInputStream(new ByteArrayInputStream(content));
String mimeType = URLConnection.guessContentTypeFromStream(is);

要从文件中获取文件，您可以使用以下代码:

For fetching from File you can use below code:

MimetypesFileTypeMap mimeTypesMap = new MimetypesFileTypeMap();
String mime = mimeTypesMap.getContentType(file);
