我们在安卓开发中,可能需要安卓发送邮件的功能。往往,我们必须手动输入账号和密码后发生邮件。这种方式费时费力,因此在这里介绍使用一种方法实现自动发送邮件的功能,我们可以用其收集bug发送邮箱等功能的实现。
一 下载jar包
Android实现发送邮件,首先需要依赖additional.jar、mail.jar和activation.jar这3个jar包。
首先前往百度网盘 密码: 8s5b下载所需要的jar包,然后将其放入app/libs文件加下
二 创建发送邮件所需要的EmailSender 类

import javax.activation.DataHandler;

public class EmailSender {
private Properties properties;
private Session session;
private Message message;
private MimeMultipart multipart;
public EmailSender() {
this.properties = new Properties();
}
public void setProperties(String host,String post){
//地址
this.properties.put("mail.smtp.host",host);
//端口号
this.properties.put("mail.smtp.post",post);
//是否验证
this.properties.put("mail.smtp.auth",true);
this.session=Session.getInstance(properties);
this.message = new MimeMessage(session);
this.multipart = new MimeMultipart("mixed");
}
/**
* 设置收件人
* @param receiver 收件人
* @throws MessagingException
*/
public void setReceiver(String[] receiver) throws MessagingException{
Address[] address = new InternetAddress[receiver.length];
for(int i=0;i<receiver.length;i++){
address[i] = new InternetAddress(receiver[i]);
}
this.message.setRecipients(Message.RecipientType.TO, address);
}
/**
* 设置邮件
* @param from 来源
* @param title 标题
* @param content 内容
* @throws AddressException
* @throws MessagingException
*/
public void setMessage(String from,String title,String content) throws AddressException, MessagingException{
this.message.setFrom(new InternetAddress(from));
this.message.setSubject(title);
//纯文本的话用setText()就行,不过有附件就显示不出来内容了
MimeBodyPart textBody = new MimeBodyPart();
textBody.setContent(content,"text/html;charset=gbk");
this.multipart.addBodyPart(textBody);
}
/**

* @param filePath 文件路径

*/
public void addAttachment(String filePath) throws MessagingException{
FileDataSource fileDataSource = new FileDataSource(new File(filePath));
DataHandler dataHandler = new DataHandler(fileDataSource);
MimeBodyPart mimeBodyPart = new MimeBodyPart();
mimeBodyPart.setDataHandler(dataHandler);
mimeBodyPart.setFileName(fileDataSource.getName());
this.multipart.addBodyPart(mimeBodyPart);
}
/**
* 发送邮件
* @param host 地址
* @param account 账户名
* @param pwd 密码
* @throws MessagingException
*/
public void sendEmail(String host,String account,String pwd) throws MessagingException{
//发送时间
this.message.setSentDate(new Date());
//发送的内容,文本和附件
this.message.setContent(this.multipart);
this.message.saveChanges();
//创建邮件发送对象,并指定其使用SMTP协议发送邮件
Transport transport=session.getTransport("smtp");
//登录邮箱
transport.connect(host,account,pwd);
//发送邮件
transport.sendMessage(message, message.getAllRecipients());
//关闭连接
transport.close();
}
}
三 发送邮件
//耗时操作要起子线程
new Thread(new Runnable() {
@Override
public void run() {
try {
EmailSender sender = new EmailSender();
//设置服务器地址和端口,可以查询网络
sender.setProperties("smtp.163.com", "25");
//分别设置发件人,邮件标题和文本内容
sender.setMessage("×××××××××@163.com", "title" + "-" +
"content");
//设置收件人
sender.setReceiver(new String[]{"×××××××@163.com"});
//添加附件换成你手机里正确的路径
// sender.addAttachment("/sdcard/emil/emil.txt");
//发送邮件
//sender.setMessage("你的163邮箱账号", "EmailS//ender", "Java Mail !");这里面两个邮箱账号要一致
sender.sendEmail("smtp.163.com", "*****@163.com", "password");
} catch (AddressException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
}
}
}).start();
