Android实现电子邮箱客户端

本文主要讲述了安卓平台上利用QQ邮箱SMTP协议，POP3协议发送与接收消息的实现

发送邮件核心代码

 import java.security.Security;    import java.util.Date;    import java.util.Properties;    import javax.mail.Authenticator;    import javax.mail.Message;    import javax.mail.MessagingException;    import javax.mail.PasswordAuthentication;    import javax.mail.Session;    import javax.mail.Transport;    import javax.mail.internet.AddressException;    import javax.mail.internet.InternetAddress;    import javax.mail.internet.MimeMessage;    /**    * 使用Gmail发送邮件    * @author Winter Lau    */    public class GmailSender {    public static void main(String[] args) throws AddressException, MessagingException {    Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());    final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";    // Get a Properties object    Properties props = System.getProperties();    props.setProperty("mail.smtp.host", "smtp.qq.com");    props.setProperty("mail.smtp.socketFactory.class", SSL_FACTORY);    props.setProperty("mail.smtp.socketFactory.fallback", "false");    props.setProperty("mail.smtp.port", "465");    props.setProperty("mail.smtp.socketFactory.port", "465");    props.put("mail.smtp.auth", "true");    final String username = "yourusername";    final String password = "yourpassword";    Session session = Session.getDefaultInstance(props, new Authenticator(){    protected PasswordAuthentication getPasswordAuthentication() {    return new PasswordAuthentication(username, password);    }});    // -- Create a new message --    Message msg = new MimeMessage(session);    // -- Set the FROM and TO fields --    msg.setFrom(new InternetAddress(username + "@qq.com"));    msg.setRecipients(Message.RecipientType.TO,    InternetAddress.parse("yourusername@qq.com",false));    msg.setSubject("Hello");    msg.setText("How are you");    msg.setSentDate(new Date());    Transport.send(msg);    System.out.println("Message sent.");    }    }

接收邮件核心代码

 import java.io.UnsupportedEncodingException;    import java.security.*;    import java.util.Properties;    import javax.mail.*;    import javax.mail.internet.InternetAddress;    import javax.mail.internet.MimeUtility;    /**    * 用于收取Gmail邮件    * @author Winter Lau    */    public class GmailFetch {    public static void main(String argv[]) throws Exception {    Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());    final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";    // Get a Properties object    Properties props = System.getProperties();    props.setProperty("mail.pop3.socketFactory.class", SSL_FACTORY);    props.setProperty("mail.pop3.socketFactory.fallback", "false");    props.setProperty("mail.pop3.port", "995");    props.setProperty("mail.pop3.socketFactory.port", "995");    //以下步骤跟一般的JavaMail操作相同    Session session = Session.getDefaultInstance(props,null);    //请将红色部分对应替换成你的邮箱帐号和密码    URLName urln = new URLName("pop3","pop.qq.com",995,null,    "yourusername@qq.com", "yourpassword");    Store store = session.getStore(urln);    Folder inbox = null;    try {    store.connect();    inbox = store.getFolder("INBOX");    inbox.open(Folder.READ_ONLY);    FetchProfile profile = new FetchProfile();    profile.add(FetchProfile.Item.ENVELOPE);    Message[] messages = inbox.getMessages();    inbox.fetch(messages, profile);    System.out.println("收件箱的邮件数：" + messages.length);    for (int i = 0; i < messages.length; i++) {    //邮件发送者    String from = decodeText(messages[i].getFrom()[0].toString());    InternetAddress ia = new InternetAddress(from);    System.out.println("FROM:" + ia.getPersonal()+'('+ia.getAddress()+')');    //邮件标题    System.out.println("TITLE:" + messages[i].getSubject());    //邮件大小    System.out.println("SIZE:" + messages[i].getSize());    //邮件发送时间    System.out.println("DATE:" + messages[i].getSentDate());    }    } finally {    try {    inbox.close(false);    } catch (Exception e) {}    try {    store.close();    } catch (Exception e) {}    }    }    protected static String decodeText(String text)    throws UnsupportedEncodingException {    if (text == null)    return null;    if (text.startsWith("=?GB") || text.startsWith("=?gb"))    text = MimeUtility.decodeText(text);    else    text = new String(text.getBytes("ISO8859_1"));    return text;    }    }

注意，接收邮件使用java客户端时可以正常得到数据，在使用安卓的时候，就会卡在store.connect(),原因不详，无法解决

问题已解决，安卓似乎强行并不允许连接网络的操作在主线程中，将store.connnect()放到子线程中即可，不然会卡住

注意，发邮件时，要导入activation.jar,不然的话会报java.lang.noClassDefFoundError:javax.activation.DataHandler

点击登陆会跳转到此处，HttpUtils如下，主要包括验证是否成功登陆与发送消息的方法，

其中创建了一个密码验证器，并且根据邮件会话属性和密码验证器构造一个发送邮件的session

HttpUtils中用到了MailInfo中一些属性，MailInfo是邮件基本信息javabean,其中配置了邮件会话属性，和其他一些属性，内容如下

由于现在是SSL方法验证，似乎都要加上

p.put("mail.smtp.starttls.enable", "true");//需要加上p.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");p.put("mail.smtp.socketFactory.port", "465");

刚开始没加就出错了

package com.email.bean;import java.io.Serializable;
import java.util.List;
import java.util.Properties;/*** 邮件的基本信息* @author Administrator**/

}

session是Application中声明的静态全局变量，info也是

package com.email.app;
import java.io.InputStream;
import java.util.ArrayList;import javax.mail.Session;
import javax.mail.Store;import com.email.bean.MailInfo;import android.app.Application;public class MyApplication extends Application {public static Session session = null;public static Store getStore() {return store;}public static void setStore(Store store) {MyApplication.store = store;}public static MailInfo info=new MailInfo();private static Store store;private ArrayList<InputStream> attachmentsInputStreams;public ArrayList<InputStream> getAttachmentsInputStreams() {return attachmentsInputStreams;}public void setAttachmentsInputStreams(ArrayList<InputStream> attachmentsInputStreams) {this.attachmentsInputStreams = attachmentsInputStreams;}}
