羊皮书APP(Android版)开发系列(十三)Android 邮件发送的实现

在app开发过程中,邮件发送功能也是一个常见的功能,用于反馈一些app信息,严重错误等。这里使用javamail-android来实现,使用javamail-android需要下载三个jar包,分别是:additionnal.jar、mail.jar、activation.jar,下载地址是:https://code.google.com/archive/p/javamail-android/downloads,如果你的网络不能访问google的话,可以到我的github上下载,地址是:https://github.com/wjie2014/javamail-android.

(1) 下载additionnal.jar、mail.jar、activation.jar,导入到自己的项目中。

(2) 创建email实体类:

package cn.studyou.parchment.mail;


import java.util.Properties;
/**
 * 基本功能:邮件实体
 * 创建:王杰
 * 创建时间:16/3/15
 * 邮箱:w489657152@gmail.com
 */
public class MailSenderInfo {
    private String mailServerHost;
    private String mailServerPort = "25";
    private String fromAddress;
    private String toAddress;
    private String userName;
    private String password;
    private boolean validate = false;
    private String subject;
    private String content;
    private String[] attachFileNames;

    public Properties getProperties() {
        Properties p = new Properties();
        p.put("mail.smtp.host", this.mailServerHost);
        p.put("mail.smtp.port", this.mailServerPort);
        p.put("mail.smtp.auth", validate ? "true" : "false");
        return p;
    }

    public String getMailServerHost() {
        return mailServerHost;
    }

    public void setMailServerHost(String mailServerHost) {
        this.mailServerHost = mailServerHost;
    }

    public String getMailServerPort() {
        return mailServerPort;
    }

    public void setMailServerPort(String mailServerPort) {
        this.mailServerPort = mailServerPort;
    }

    public boolean isValidate() {
        return validate;
    }

    public void setValidate(boolean validate) {
        this.validate = validate;
    }

    public String[] getAttachFileNames() {
        return attachFileNames;
    }

    public void setAttachFileNames(String[] fileNames) {
        this.attachFileNames = fileNames;
    }

    public String getFromAddress() {
        return fromAddress;
    }

    public void setFromAddress(String fromAddress) {
        this.fromAddress = fromAddress;
    }

    public String getPassword() {
        return password;
    }

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

    public String getToAddress() {
        return toAddress;
    }

    public void setToAddress(String toAddress) {
        this.toAddress = toAddress;
    }

    public String getUserName() {
        return userName;
    }

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

    public String getSubject() {
        return subject;
    }

    public void setSubject(String subject) {
        this.subject = subject;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String textContent) {
        this.content = textContent;
    }
} 

(3) 创建邮件认证实体:

package cn.studyou.parchment.mail;

import javax.mail.*;
/**
 * 基本功能:邮件认证
 * 创建:王杰
 * 创建时间:16/3/15
 * 邮箱:w489657152@gmail.com
 */
public class MailAuthenticator extends Authenticator{
    String userName=null;
    String password=null;
     
    public MailAuthenticator(){
    }
    public MailAuthenticator(String username, String password) {
        this.userName = username; 
        this.password = password; 
    } 
    protected PasswordAuthentication getPasswordAuthentication(){
        return new PasswordAuthentication(userName, password);
    }
}
 

(4) 创建简单邮件发送器:

package cn.studyou.parchment.mail;

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

import javax.mail.Address;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
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;

/**
 * 基本功能:简单邮件(不带附件的邮件)发送器
 * 创建:王杰
 * 创建时间:16/3/15
 * 邮箱:w489657152@gmail.com
 */
public class SimpleMailSender {
    /**
     * 以文本格式发送邮件
     *
     * @param mailInfo 待发送的邮件的信息
     */
    public boolean sendTextMail(MailSenderInfo mailInfo) {
        // 判断是否需要身份认证
        MailAuthenticator authenticator = null;
        Properties pro = mailInfo.getProperties();
        if (mailInfo.isValidate()) {
            // 如果需要身份认证,则创建一个密码验证器
            authenticator = new MailAuthenticator(mailInfo.getUserName(), mailInfo.getPassword());
        }
        // 根据邮件会话属性和密码验证器构造一个发送邮件的session
        Session sendMailSession = Session.getDefaultInstance(pro, authenticator);
        try {
            // 根据session创建一个邮件消息
            Message mailMessage = new MimeMessage(sendMailSession);
            // 创建邮件发送者地址
            Address from = new InternetAddress(mailInfo.getFromAddress());
            // 设置邮件消息的发送者
            mailMessage.setFrom(from);
            // 创建邮件的接收者地址,并设置到邮件消息中
            Address to = new InternetAddress(mailInfo.getToAddress());
            mailMessage.setRecipient(Message.RecipientType.TO, to);
            // 设置邮件消息的主题
            mailMessage.setSubject(mailInfo.getSubject());
            // 设置邮件消息发送的时间
            mailMessage.setSentDate(new Date());
            // 设置邮件消息的主要内容
            String mailContent = mailInfo.getContent();
            mailMessage.setText(mailContent);
            // 发送邮件
            Transport.send(mailMessage);
            return true;
        } catch (MessagingException ex) {
            ex.printStackTrace();
        }
        return false;
    }

    /**
     * 以HTML格式发送邮件
     *
     * @param mailInfo 待发送的邮件信息
     */
    public static boolean sendHtmlMail(MailSenderInfo mailInfo) {
        // 判断是否需要身份认证
        MailAuthenticator authenticator = null;
        Properties pro = mailInfo.getProperties();
        //如果需要身份认证,则创建一个密码验证器
        if (mailInfo.isValidate()) {
            authenticator = new MailAuthenticator(mailInfo.getUserName(), mailInfo.getPassword());
        }
        // 根据邮件会话属性和密码验证器构造一个发送邮件的session
        Session sendMailSession = Session.getDefaultInstance(pro, authenticator);
        try {
            // 根据session创建一个邮件消息
            Message mailMessage = new MimeMessage(sendMailSession);
            // 创建邮件发送者地址
            Address from = new InternetAddress(mailInfo.getFromAddress());
            // 设置邮件消息的发送者
            mailMessage.setFrom(from);
            // 创建邮件的接收者地址,并设置到邮件消息中
            Address to = new InternetAddress(mailInfo.getToAddress());
            // Message.RecipientType.TO属性表示接收者的类型为TO
            mailMessage.setRecipient(Message.RecipientType.TO, to);
            // 设置邮件消息的主题
            mailMessage.setSubject(mailInfo.getSubject());
            // 设置邮件消息发送的时间
            mailMessage.setSentDate(new Date());
            // MiniMultipart类是一个容器类,包含MimeBodyPart类型的对象
            Multipart mainPart = new MimeMultipart();
            // 创建一个包含HTML内容的MimeBodyPart
            BodyPart html = new MimeBodyPart();
            // 设置HTML内容
            html.setContent(mailInfo.getContent(), "text/html; charset=utf-8");
            mainPart.addBodyPart(html);
            // 将MiniMultipart对象设置为邮件内容
            mailMessage.setContent(mainPart);
            // 发送邮件
            Transport.send(mailMessage);
            return true;
        } catch (MessagingException ex) {
            ex.printStackTrace();
        }
        return false;
    }
} 


(5) 创建邮件工具类:

package cn.studyou.parchment.utils;

import android.content.Context;

import cn.studyou.baselibrary.log.L;
import cn.studyou.parchment.mail.MailSenderInfo;
import cn.studyou.parchment.mail.SimpleMailSender;

/**
 * 基本功能:发送邮件
 * 创建:王杰
 * 创建时间:16/3/21
 * 邮箱:w489657152@gmail.com
 */
public class EmailUtil {
    public static void autoSendMail(Context context, String msuggestions) {
        MailSenderInfo mailInfo = new MailSenderInfo();
        mailInfo.setMailServerHost("smtp.xxx.com");//smtp地址
        mailInfo.setMailServerPort("25");
        mailInfo.setValidate(true);
        mailInfo.setUserName("username");//邮箱名字
        mailInfo.setPassword("password");// 邮箱密码
        mailInfo.setFromAddress("xxx@sina.com");// 发送方邮件地址
        mailInfo.setToAddress("xxx@qq.com");//接受方邮件地址
        mailInfo.setSubject("subject");
        mailInfo.setContent(msuggestions);
        // 这个类主要来发送邮件
        SimpleMailSender sms = new SimpleMailSender();
        sms.sendTextMail(mailInfo);// 发送文体格式
        L.e(msuggestions);
        // sms.sendHtmlMail(mailInfo);// 发送html格式
    }
}

(6) 在需要发送邮件的地方使用EmailUtil的autoSendMail方法即可,需要开线程开发送。

 new Thread(new Runnable() {
                            @Override
                            public void run() {
                                EmailUtil.autoSendMail(getApplicationContext(), "我发送的邮件,请接收");
                            }
                        }).start();

(7) 程序运行或打包过程中可能会报错,处理办法,在proguard-rules.pro文件中添加如下代码:

-dontwarn javax.activation.**

-keep class javax.activation.** { *;}

-dontwarn javax.mail.**

-keep class javax.mail.** { *;}

到这里,我们就完成了一个邮件发送的工具,以后使用的时候,我们只需要修改EmailUtil.java工具类就可以完成邮件发送功能了。
