我正在使用JavaMail在我的Android应用程序中阅读邮件。我试图涵盖所有组合，即在自定义服务器/Gmail ID/Live ID上发送/接收的邮件。

从GMail with Attachment发送的一些邮件出现了问题。我可以接收附件，但内容返回javax.mail.internet.MimeMultipart@44f2e698

以下是用于接收和读取消息的代码：

    Properties props = System.getProperties();
    props.setProperty("mail.store.protocol", "imap");

    try {
     /* Create the session and get the store for read the mail. */
     Session session = Session.getInstance(props, null);
     Store store = session.getStore("imaps");
     store.connect("imap.gmail.com", Username, Password);

     /* Mention the folder name which you want to read. */
     Folder inbox = store.getFolder("INBOX");
     System.out.println("No of Unread Messages : " + inbox.getUnreadMessageCount());         

     /* Open the inbox using store. */
     inbox.open(Folder.READ_ONLY);

     Message messages[] = inbox.getMessages();       
     Log.d("Inbox", "Message Count: "+inbox.getMessageCount());

     for (int i = messages.length - 1 ; i > 0; --i) {
         Log.i("ContentType", "ContentType: "+messages[i].getContentType());

         Object msgContent = messages[i].getContent();

         String content = "";

         /* Check if content is pure text/html or in parts */            
         if (msgContent instanceof Multipart) {

             Multipart multipart = (Multipart) msgContent;

             Log.e("BodyPart", "MultiPartCount: "+multipart.getCount());

             for (int j = 0; j < multipart.getCount(); j++) {

              BodyPart bodyPart = multipart.getBodyPart(j);

              String disposition = bodyPart.getDisposition();

              if (disposition != null && (disposition.equalsIgnoreCase("ATTACHMENT"))) { // BodyPart.ATTACHMENT doesn't work for gmail
                  System.out.println("Mail have some attachment");

                  DataHandler handler = bodyPart.getDataHandler();
                  System.out.println("file name : " + handler.getName());                                 
                }
              else { 
                  System.out.println("Content: "+bodyPart.getContent());
                  content= bodyPart.getContent().toString();
                }
            }
         }
         else                
             content= messages[i].getContent().toString();

我对问题邮件的了解：

> < li>

getFrom也返回姓名，即它采用以下格式:名字姓氏

多部分包含两个身体部分:
