Android 客户端发送邮件（JMail方式）

项目用到了Android 客户端发送邮件，不能够使用Android 的服务，那就用JMail喽，本来以为很简单的事情折腾了好半天才搞定！

必须的jar

• mail.jar
• activation.jar
• additionnal.jar.zip

首先是调用的代码：

		Mail m = new Mail("******@gmail.com", "密码");
		String[] toArr = { "569629066@qq.com"};
		m.set_to(toArr);
		m.set_from("Vesti_Yang");
		m.set_subject("Android 客户端测试邮件");
		m.set_body("Android 客户端测试链接\n\n https://img-my.youkuaiyun.com/uploads/201210/29/1351508410_1812.png");

		try
		{
			//m.addAttachment("/sdcard/filelocation");
			if (m.send())
			{
				Toast.makeText(MainActivity.this, "邮件发送成功", Toast.LENGTH_LONG).show();
			}
			else
			{
				Toast.makeText(MainActivity.this, "邮件发送失败", Toast.LENGTH_LONG).show();
			}
		}
		catch (Exception e)
		{
			e.printStackTrace();
		}

Mail.java的实现：

public class Mail extends javax.mail.Authenticator
{
	private String		_user;
	private String		_pass;

	private String[]	_to;
	private String		_from;

	private String		_port;
	private String		_sport;

	private String		_host;

	private String		_subject;
	private String		_body;

	private boolean		_auth;

	private boolean		_debuggable;

	private Multipart	_multipart;


	public Mail()
	{
		// 邮件服务器，QQ邮箱就用smtp.qq.com，其它类似
		_host = "smtp.gmail.com";
		// smtp 端口
		_port = "465";
		// socketfactory 端口
		_sport = "465";

		_user = "";
		_pass = "";
		_from = "";
		_subject = "";
		_body = "";

		_debuggable = false;
		 // smtp默认验证
		_auth = true;

		_multipart = new MimeMultipart();

		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);
	}

	public Mail(String user, String pass)

	public boolean send() throws Exception
	{

		if (!_user.equals("") && !_pass.equals("") && _to.length > 0 && !_from.equals("") && !_subject.equals("") && !_body.equals(""))
		{
			Session session = Session.getInstance(props, this);
			MimeMessage msg = new MimeMessage(session);
			msg.setFrom(new InternetAddress(_from));
			InternetAddress[] addressTo = new InternetAddress[_to.length];
			for (int i = 0; i < _to.length; i++)
			{
				addressTo[i] = new InternetAddress(_to[i]);
			}
			msg.setRecipients(MimeMessage.RecipientType.TO, addressTo);

	}
