Android上發送帶附件的郵件

在android上發送郵件方式：

第一種：借助GMail APP客戶端，缺點是必須使用GMail帳號，有點是比較方便

不需要寫很多代碼，但是不是很靈活。

第二種：基於JMail實現，可以很靈活的自己設置各種屬性，不需要GMail帳號

在第二種方式的實現之前，看一下JMail對EMail結構的劃分：

基於SMTP協議發送EMail，所以客戶端必須要知道SMTP的主機

騰訊郵件的SMTP主機為：stmp.qq.com端口為465基於SSL協議

最後我做了一個簡單的封裝，把發送文本加圖像附件的功能做出了

一個單獨的Class，只要調用一下即可完成：

package com.gloomyfish.jmail.demo;

import java.util.Date;
import java.util.Properties;

import javax.activation.DataHandler;
import javax.activation.DataSource;
import javax.activation.FileDataSource;
import javax.mail.Address;
import javax.mail.Message;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

public class EMailSender {

	private String host;
	private String port;
	private String userName;
	private String password;
	private String[] images;

	public String[] getImagePath() {
		return images;
	}

	public void setImagePath(String[] imagePath) {
		this.images = imagePath;
	}

	public EMailSender(String host, String port, String userName, String password) 
	{
		this.host = host;
		this.port = port;
		this.userName = userName;
		this.password = password;
	}

	public void sendEmail(String subject, String recepits, String sender, String content) 
	{
		Properties props = new Properties();
		props.put(mail.smtp.host, host);  //設置smtp的服務器地址
		// props.put(mail.smtp.starttls.enable, true);
		// props.put(mail.smtp.port, port); // 設置端口
		// props.put(mail.smtp.auth, true); //設置smtp服務器要身份驗證。
		
		props.put(mail.smtp.socketFactory.port, port);
		props.put(mail.smtp.socketFactory.class, javax.net.ssl.SSLSocketFactory);
		props.put(mail.smtp.auth, true);
		props.put(mail.smtp.port, port);
		
		// 返回授權Base64編碼
		PopupAuthenticator auth = new PopupAuthenticator(userName, password);
		// 獲取會話對象
		Session session = Session.getInstance(props, auth);	
		// 設置為DEBUG模式
		session.setDebug(true);
		
		// 郵件內容對象組裝
		MimeMessage message = new MimeMessage(session);
		try
		{
			Address addressFrom = new InternetAddress(sender, Jia Zhi Gang);
			Address addressTo = new InternetAddress(recepits, My QQ E-Mail);
			message.setSubject(subject);
			message.setSentDate(new Date());
			message.setFrom(addressFrom);
			message.addRecipient(Message.RecipientType.TO,addressTo);
			 
			// 郵件文本/HTML內容
			Multipart multipart = new MimeMultipart();
			MimeBodyPart messageBodyPart = new MimeBodyPart();
	        messageBodyPart.setContent(content, text/html);
	        multipart.addBodyPart(messageBodyPart);
	        
	        // 添加郵件附件
	        if (images != null && images.length > 0) {
	            for (String filePath : images) {
	                MimeBodyPart attachPart = new MimeBodyPart();	 
	                DataSource source = new FileDataSource(filePath);
	                attachPart.setDataHandler(new DataHandler(source));
	                attachPart.setFileName(filePath);
	                multipart.addBodyPart(attachPart);
	            }
	        }

	        // 保存郵件內容
	        message.setContent(multipart);
			
			// 獲取SMTP協議客戶端對象，連接到指定SMPT服務器
			Transport transport = session.getTransport(smtp);
			transport.connect(host, Integer.parseInt(port), userName, password);
			System.out.println(connet it success!!!!);
			
			// 發送郵件到SMTP服務器
			Thread.currentThread().setContextClassLoader( getClass().getClassLoader() );
			Transport.send(message);
			System.out.println(send it success!!!!);
			
			// 關閉連接
			transport.close();
		}
		catch(Exception e)
		{
			e.printStackTrace();
		}
	}

	public String getHost() {
		return host;
	}

	public void setHost(String host) {
		this.host = host;
	}

	public String getPort() {
		return port;
	}

	public void setPort(String port) {
		this.port = port;
	}

	public String getUserName() {
		return userName;
	}

	public void setUserName(String userName) {
		this.userName = userName;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

}

用戶授權類：

package com.gloomyfish.jmail.demo;


import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;


class PopupAuthenticator extends Authenticator {
	private String userName;
	private String password;
	public PopupAuthenticator(String userName, String password)
	{
		this.userName = userName;
		this.password = password;
	}
    public PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(userName, password);
    }
}

1.在android上發送郵件必須自己導入三個相關的JAVA文件
