概要

最近在和解决用户反馈的问题,但是出现了不方便的事情.就是获取用户操作日志的问题.想来想去还是用比较隐晦的方法---发送邮件.(需要告知用户,不然会当成流氓的!)

发送邮件分为两种:

调用系统的发邮件功能发送邮件
使用特定的邮箱密码发送邮件

第一种需要用户登陆邮箱,有的用户可能还没有邮箱,不是很方便.所以采用第二种方法:

在APP内部埋好邮箱,密码给特定的邮箱发送邮件附件添加日志.

发送说明

发送基础

这里要使用JavaMail的三个jar包:

activation.jar
additionnal.jar
mail.jar

发送流程

设置发送服务器
设置发送账户和密码
设置发送显示的名称,主题,内容和附件
设置接收者地址
发送邮件给接收者

发送实现

权限

发送带有附件的邮件,需要联网权限和读写SD卡权限,需要在Android Manifest.xml文件添加已下权限:

<uses-permission android:name="android.permission.INTERNET"/>

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

设置发送信息

以下以163邮箱为例,需要提前在163邮箱设置里面开启smtp.

设置需要的常量

//发送账户private static final String SENDER_NAME = "xxxxx@163.com";//发送账户的密码private static final String SENDER_PASS = "xxxxx";//邮箱服务器private static final String VALUE_MAIL_HOST = "smtp.163.com";//邮箱服务器主机private static final String KEY_MAIL_HOST = "mail.smtp.host";//邮箱是否需要鉴权private static final String KEY_MAIL_AUTH = "mail.smtp.auth";//需要鉴权private static final String VALUE_MAIL_AUTH = "true";

设置发送的属性

Properties properties = System.getProperties();
properties.put(KEY_MAIL_HOST, VALUE_MAIL_HOST);
properties.put(KEY_MAIL_AUTH, VALUE_MAIL_AUTH);

获取Session

Session session = Session.getInstance(properties, getAuthenticator());
private Authenticator getAuthenticator() {    return new Authenticator(){        @Override
       protected PasswordAuthentication getPasswordAuthentication() {            return new PasswordAuthentication(SENDER_NAME, SENDER_PASS);
       }
   };
}

构建邮件消息

//创建消息MimeMessage mimeMessage = new MimeMessage(session);
try {    //设置发送者
   mimeMessage.setFrom(new InternetAddress(SENDER_NAME));    //设置接收者
   InternetAddress[] addresses = new InternetAddress[]{new InternetAddress(SENDER_NAME)};
   mimeMessage.setRecipients(Message.RecipientType.TO, addresses);    //设置邮件的主题
   mimeMessage.setSubject(title);    //设置邮件的内容
   MimeBodyPart textPart = new MimeBodyPart();
   textPart.setContent(content, "text/html");
   Multipart multipart = new MimeMultipart();
   multipart.addBodyPart(textPart);
   mimeMessage.setContent(multipart);    //设置发送时间
   mimeMessage.setSentDate(new Date());
} catch (MessagingException e) {
   e.printStackTrace();
}

添加文件附件

private void appendFile(MimeMessage message, String filePath) {    
try {
       Multipart multipart = (Multipart) message.getContent();
       MimeBodyPart filePart = new MimeBodyPart();
       filePart.attachFile(filePath);
       multipart.addBodyPart(filePart);
   } catch (IOException e) {
       e.printStackTrace();
   } catch (MessagingException e) {
       e.printStackTrace();
   }
}

添加多个文件附件

private void appendMultiFile(MimeMessage message, List<String> pathList) {    
try {
   Multipart multipart = (Multipart) message.getContent();       
           for (String path : pathList) {
           MimeBodyPart filePart = new MimeBodyPart();
           filePart.attachFile(path);
           multipart.addBodyPart(filePart);
       }
   } catch (IOException e) {
       e.printStackTrace();
   } catch (MessagingException e) {
       e.printStackTrace();
   }
}

发送邮件

Transport.send(mimeMessage);

发送结果

1.不带附件的邮件:

// 此处省略

2.带附件的邮件

// 此处省略

完整的发送代码

为了方便使用,就写了个发送邮件的单例,代码如下:
