是否可以在 Android 中使用 Javamail 接收邮件

Question

这几天我在学习 Javamail，关注这个网站： http://www.tutorialspoint.com/javamail_api/

我测试了发送并添加了一些额外的东西，因为它是在 Android 上运行的！

但是当我尝试按照接收电子邮件教程进行操作时，情况已经完全改变了，这让我感到奇怪..

是否可以制作此代码： https://www.tutorialspoint.com/javamail_api/javamail_api_fetching_emails.htm

适用于android但使用XML接口？！

您可以使用以下代码：

public static void receiveEmail(String pop3Host, String storeType, user, String password) {
        try {
            //1) get the session object  
            Properties properties = new Properties();
            properties.put("mail.pop3.host", pop3Host);
            Session emailSession = Session.getDefaultInstance(properties);

            //2) create the POP3 store object and connect with the pop server  
            POP3Store emailStore = (POP3Store) emailSession.getStore(storeType);
            emailStore.connect(user, password);

            //3) create the folder object and open it  
            Folder emailFolder = emailStore.getFolder("INBOX");
            emailFolder.open(Folder.READ_ONLY);

            //4) retrieve the messages from the folder in an array and print it  
            Message[] messages = emailFolder.getMessages();
            for (int i = 0; i < messages.length; i++) {
                Message message = messages[i];
                System.out.println("---------------------------------");
                System.out.println("Email Number " + (i + 1));
                System.out.println("Subject: " + message.getSubject());
                System.out.println("From: " + message.getFrom()[0]);
                System.out.println("Text: " + message.getContent().toString());
            }

            //5) close the store and folder objects  
            emailFolder.close(false);
            emailStore.close();

        } catch (NoSuchProviderException e) {
            e.printStackTrace();
        } catch (MessagingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

调用你的方法传递一些参数：

String host = "pop.gmail.com";//change accordingly  
String mailStoreType = "pop3";  
String username= "example@gmail.com";  
String password= "xxxxx";//change accordingly  

receiveEmail(host, mailStoreType, username, password);
