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

11 |
public MyAuthenticator(String username, String password) {
|
12 |
this .userName = username;
|
13 |
this .password = password;
|
15 |
protected PasswordAuthentication getPasswordAuthentication(){
|
16 |
return new PasswordAuthentication(userName, password);
|
下面给出使用上面三个类的代码:
01 |
public static void main(String[] args){
|
03 |
MultiMailSenderInfo mailInfo = new MultiMailSenderInfo();
|
04 |
mailInfo.setMailServerHost( "smtp.163.com" );
|
05 |
mailInfo.setMailServerPort( "25" );
|
06 |
mailInfo.setValidate( true );
|
07 |
mailInfo.setUserName( "xxx@163.com" );
|
08 |
mailInfo.setPassword( "**********" );
|
09 |
mailInfo.setFromAddress( "xxx@163.com" );
|
10 |
mailInfo.setToAddress( "xxx@163.com" );
|
11 |
mailInfo.setSubject( "设置邮箱标题" );
|
12 |
mailInfo.setContent( "设置邮箱内容" );
|
13 |
String[] receivers = new String[]{ "***@163.com" , "***@tom.com" };
|
14 |
String[] ccs = receivers; mailInfo.setReceivers(receivers);
|
17 |
MultiMailsender sms = new MultiMailsender();
|
18 |
sms.sendTextMail(mailInfo);
|
19 |
MultiMailsender.sendHtmlMail(mailInfo);
|
20 |
MultiMailsender.sendMailtoMultiCC(mailInfo);
|
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("xxx@163.com");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>
