我在Android上阅读了很多关于电子邮件的博客和论坛......我现在的目标是从 POP3邮件服务器下载传入的电子邮件... 一个巨大的信息列表，如何发送电子邮件，但同时有关于 HOWTO RECEIVE 的电子邮件，其中包含附件的 NO 信息，并以编程方式保存附件在 SD卡 ...
上请，任何帮助表示赞赏!!!
最接近的意思是例如...... Android: Correctly downloading/saving an email attachement
此代码适用于java中的PC！
package com.tsysv.mail;
import java.io.IOException;
import java.util.Properties;
import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.NoSuchProviderException;
import javax.mail.Session;
import com.sun.mail.pop3.POP3Store;
public class EmailReceiveTest {
public static void main(String[] args) {
String mailPop3Host = "pop3.***.**";
String mailStoreType = "pop3";
String mailUser = "*****";
String mailPassword = "******";
receiveEmail(mailPop3Host, mailStoreType, mailUser, mailPassword);
}
public static void receiveEmail(String pop3Host, String storeType, String user, String password) {
try {
Properties properties = new Properties();
properties.put("mail.pop3.host", pop3Host);
Session emailSession = Session.getDefaultInstance(properties);
POP3Store emailStore = (POP3Store) emailSession.getStore(storeType);
emailStore.connect(user, password);
Folder emailFolder = emailStore.getFolder("INBOX");
emailFolder.open(Folder.READ_ONLY);
Message[] messages = emailFolder.getMessages();
for (int i = 0; i < messages.length; i++) {
Message message = messages[i];
System.out.println("==============================");
System.out.println("Email #" + (i + 1));
System.out.println("Subject: " + message.getSubject());
System.out.println("From: " + message.getFrom()[0]);
System.out.println("Text: " + message.getContent().toString());
}
emailFolder.close(false);
emailStore.close();
} catch (NoSuchProviderException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
但是在Android上实现它会在StackTrace中出现这样的错误......
