使用JavaMail发邮件
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
