Android pop3与imap方式接收邮件(javamail)
需要下载3个jar包:mail.jar/ activation.jar/ additionnal.jar
1.pop3
/**
* 以pop3方式读取邮件,此方法不能读取邮件是否为已读,已经通过测试

"邮箱名(没有@163.com)", "密码");
// 邮件协议为pop3,邮件服务器是pop3.163.com,端口为110,用户名/密码为abcw111222/123456w
Store store = session.getStore(urln);
store.connect();
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_WRITE);
Message message[] = folder.getMessages();
if (message.length > ) {
Map<String, Object> map;

// 得到收件箱文件夹信息,获取邮件列表
List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
System.out.println("未读邮件数:" + folder.getUnreadMessageCount());
Message[] messages = folder.getMessages();
if (messages.length > ) {

ReciveOneMail pmm = null;

try {

String read;
Flags flags = messages[i].getFlags();
if (flags.contains(Flags.Flag.SEEN)) {
System.out.println("这是一封已读邮件");
isRead = true;

} else {

下面为用到的一个类,用来读取除了判断是否已读的信息之外的内容
