本文实例讲解了基于基于jmail实现android邮件发送功能,分享给大家供大家参考,具体内容如下
在android上发送邮件方式:
第一种:借助gmail app客户端,缺点是必须使用gmail帐号,有一点是比较方便,不需要写很多代码,但是不是很灵活。
第二种:基于jmail实现,可以很灵活的自己设置各种属性,不需要gmail帐号
在第二种方式的实现之前,看一下jmail对email结构的划分:
基于smtp协议发送email,所以客户端必须要知道smtp的主机。
腾讯邮件的smtp主机为:stmp.qq.com端口为465基于ssl协议。
最后我做了一个简单的封装,把发送文本加图像附件的功能做出了。
一个单独的class,只要调用一下即可完成:

特别注意:
在android上发送邮件必须自己导入三个相关的java文件
以上就是本文的全部内容,希望对大家的学习android软件编程有所帮助。
