android 邮件开发(javax.mail)

    以前在csdn上发贴求助android邮件开发的开发，后来问题自己解决了。有很多网友遇到了同样的问题，发邮件问我都没及时回复。在这里我把封存装的email源代码贴出来，和大家分享。
    android开发邮件需要添加三个扩展包：mail.jar,additional.jar,和activation.jar。直接用java开发，则只需前面两个包。两种不同的开发方式，包的版本是不同的。
    封装了一个SMailSender 类，类是Runnable的实现，也就是邮件功能可作为一个线程在后台运行。SMailSender类目前只支持gmail、126和163三种邮箱，如果要支持其他邮箱，可根据邮箱的协议类型进行相应的扩展。

SMailSender.java

    上面的类调用比较简单，再给一个使用的实例MailBackground.java:

package com.jia.test;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;

public class MailBackground extends Activity{

	@Override

			}
        });

	}
	
	Runnable r = new Runnable(){

			}
		};
		
	protected void Monitor() {

	}

}

    OK，你可以发送以上三种格式的邮件了。
