Question

我正在开发一个android的电子邮件客户端应用程序。对于这些我使用 Java-Mail API实施 IMAP 客户端。我还添加了folder.addMessageCountListener，但无法收听新电子邮件＆＃39 ; S。我也试过 folder.idle（），但没有成功。以下是我使用的代码：

new Thread(new Runnable() {
   @Override
   public void run() {
      MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap();
      mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
      mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");
      mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain");
      mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed");
      mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822");
      CommandMap.setDefaultCommandMap(mc);

      Properties properties = getServerProperties("imap", "mail.xyz.com", "143");

      try {
         Session session = Session.getDefaultInstance(properties);
         Store store = session.getStore("imap");

         store.connect(txt_name.getText().toString().trim(), txt_pwd.getText().toString().trim());
         Folder[] f = store.getDefaultFolder().list();

         // opens the inbox folder
         folderInbox = store.getFolder("INBOX");
         folderInbox.open(Folder.READ_WRITE);

         //how many emails in the inbox
         int count = folderInbox.getMessageCount();

         folderInbox.addMessageCountListener(new MessageCountListener() {
         @Override
         public void messagesAdded(MessageCountEvent messageCountEvent) {
            System.out.println("New Mails event fired.");
            }

         @Override
         public void messagesRemoved(MessageCountEvent messageCountEvent) {

            }
         });
         if (folderInbox instanceof IMAPFolder) {
            IMAPFolder fol = (IMAPFolder)folderInbox;
            fol.idle();
         }              
      } catch (NoSuchProviderException e) {
                        e.printStackTrace();
      } catch (MessagingException e) {
                        e.printStackTrace();
      }
   }
}).start();

这是我的 Java Mail Debug 输出。完成调试报告。

无法收听新邮件。 folder.addMessageCountListener（）不起作用
