android 使用javamail收发邮件

1 发送邮件

今天学习了一下JavaMail，javamail发送邮件确实是一个比较麻烦的问题不用第三方邮件程序。为了以后使用方便，自己写了段代码.

Javamail-Android配置步骤：

1. 下载Android版本JavaMail包，additional.jar、mail.jar和activation.jar，下载地址JavaMail-Android

2. 在项目与src同一目录级别下，新建文件夹lib，将下载的3个jar包放入该文件夹

3. 右键->Properties->Java Build Path->Libraries，选择Add External JARs，找到项目下lib目录的3个jar包

我的代码有三个类：  
第一个类：MailSenderInfo.java

01 package com.util.mail;
02 /**
03 * 发送邮件需要使用的基本信息
04 */
05 importjava.util.Properties;
06 public classMailSenderInfo {
07     // 发送邮件的服务器的IP和端口
08     privateString mailServerHost;
09     privateString mailServerPort = "25";
10     // 邮件发送者的地址
11     privateString fromAddress;
12     // 邮件接收者的地址
13     privateString toAddress;
14     // 登陆邮件发送服务器的用户名和密码
15     privateString userName;
16     privateString password;
17     // 是否需要身份验证
18     private booleanvalidate = false;
19     // 邮件主题
20     privateString subject;
21     // 邮件的文本内容
22     privateString content;
23     // 邮件附件的文件名
24     privateString[] attachFileNames;
25     /**

65     publicString getPassword() {

67     }
68     public voidsetPassword(String password) {

70     }
71     publicString getToAddress() {
72       returntoAddress;
73     }
74     public voidsetToAddress(String toAddress) {
75       this.toAddress = toAddress;
76     }
77     publicString getUserName() {
78       returnuserName;
79     }
80     public voidsetUserName(String userName) {

82     }
83     publicString getSubject() {
84       returnsubject;
85     }

87       this.subject = subject;
88     }
89     publicString getContent() {

91     }
92     public voidsetContent(String textContent) {

199             this.receivers = receivers;
200         }
201     }
202 }

第三个类：MyAuthenticator.java

01 package com.util.mail;
02
03 import javax.mail.*;
04
05 public class MyAuthenticator extends Authenticator{
06     String userName=null;
07     String password=null;
08
09     public MyAuthenticator(){
10     }
11     publicMyAuthenticator(String username, String password) {
12         this.userName = username;
13         this.password = password;
14     }
15     protected PasswordAuthentication getPasswordAuthentication(){
16         return new PasswordAuthentication(userName, password);
17     }
18 }

下面给出使用上面三个类的代码：

01 public static void main(String[] args){
02          //这个类主要是设置邮件
03       MultiMailSenderInfo mailInfo = newMultiMailSenderInfo();
04       mailInfo.setMailServerHost("smtp.163.com");
05       mailInfo.setMailServerPort("25");
06       mailInfo.setValidate(true);
07       mailInfo.setUserName("[e-mail]");
08       mailInfo.setPassword("**********");//您的邮箱密码
09       mailInfo.setFromAddress("[e-mail]");
10       mailInfo.setToAddress("[e-mail]");
11       mailInfo.setSubject("设置邮箱标题");
12       mailInfo.setContent("设置邮箱内容");
13       String[] receivers = newString[]{"***@163.com", "***@tom.com"};
14       String[] ccs = receivers; mailInfo.setReceivers(receivers);
15       mailInfo.setCcs(ccs);
16       //这个类主要来发送邮件
17       MultiMailsender sms = newMultiMailsender();
18       sms.sendTextMail(mailInfo);//发送文体格式
19       MultiMailsender.sendHtmlMail(mailInfo);//发送html格式
20       MultiMailsender.sendMailtoMultiCC(mailInfo);//发送抄送

最后，给出朋友们几个注意的地方：  
1、使用此代码你可以完成你的javamail的邮件发送功能、发多个邮箱。三个类缺一不可。  
2、这三个类我打包是用的com.util.mail包，如果不喜欢，你可以自己改，但三个类文件必须在同一个包中  
3、不要使用你刚刚注册过的邮箱在程序中发邮件，如果你的163邮箱是刚注册不久，那你就不要使用“smtp.163.com”。因为你发不出去。刚注册的邮箱是不会给你这种权限的，也就是你不能通过验证。要使用你经常用的邮箱，而且时间比较长的。  
4、另一个问题就是mailInfo.setMailServerHost("smtp.163.com");与mailInfo.setFromAddress("[e-mail]");这两句话。即如果你使用163smtp服务器，那么发送邮件地址就必须用163的邮箱，如果不的话，是不会发送成功的。  
5、关于javamail验证错误的问题，网上的解释有很多，但我看见的只有一个。就是我的第三个类。你只要复制全了代码，我想是不会有问题的。

6、 然后在Android项目中添加网络访问权限

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