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。
