我加了下面一组代码，这对我很有用。

这帮助我发送了附件。

private Message createMessage(String email, String subject, String messageBody, Session session) throws MessagingException, UnsupportedEncodingException { 
     Message message = new MimeMessage(session); 
     message.setFrom(new InternetAddress("tutorials@tiemenschut.com", "AutoScreenShot Application")); 
     message.addRecipient(Message.RecipientType.TO, new InternetAddress(email, email)); 
     message.setSubject(subject); 
     message.setText(messageBody); 
     MimeBodyPart messageBodyPart = new MimeBodyPart(); 

     Multipart multipart = new MimeMultipart(); 

     messageBodyPart = new MimeBodyPart(); 
     String file = "/sdcard/Pictures/screenshot.png"; 
     String fileName = "screenshot.png"; 
     DataSource source = new FileDataSource(file); 
     messageBodyPart.setDataHandler(new DataHandler(source)); 
     messageBodyPart.setFileName(fileName); 
     multipart.addBodyPart(messageBodyPart); 

     message.setContent(multipart); 

     return message; 
    }
