使用之前,必须了解的基本概念与核心类:Session是邮件操作的接口;Transport是收发邮件所使用的协议,一般Session会有多个Transport;Message是收发操作的单位;Store是消息的集合,类似邮件客户端。每个Store包含一系列的Folder和Message,每个Folder又包含一系列的Folder和Message。
Session需要使用java,mail.util.Properties来构造,常用的用来构造Sess

今天修改了一个很重要的Bug,这个BUG会不断向服务端请求相同的URL,主要原因是keyRepeated用了keyPressed处理方法,当遇到FIRE事件时,就会处于死循环,解决的办法把keyRepeated和keyPressed相分离,keyRepeated只需处理的是UP,DOWN,LEFT,RIGHT事件,不必处理FIRE事件,平时开发可能会遇到此问题,把事件分开处理就行了。

Back to RTPSourceStream and StreamingDataSource
With the protocol handler in place, let's revisit the RTPSourceStream and StreamingDataSource classes from earlier, where they contained only place-holder methods. The StreamingDataSource is simple to code:

Creating an RTSP Protocol Handler
Recall that RTSP is the actual protocol over which streaming commands are initiated, through which the RTP packets are received. The RTSP protocol is like a command initiator, a bit like HTTP. For a really good explanation of a typical RTSP session, please see these ...

Since my book on Mobile Media API (MMAPI), Pro Java ME MMAPI: Mobile Media API for Java Micro Edition, was published in May, I have been inundated with requests to help readers with streaming content via MMAPI for Java-enabled mobile devices. This topic was an important omission from the book, but on ...

最近在研究J2ME实现RTSP协议,在索爱开发网站中看到一个类,但只能用于支持RTSP协议的手机,大部分手机需利用J2ME MMAPI实现,而对于自己实现的RTSP,虽然做了一些测试,调通了一点,但还没能真正运行,不知播放的效果如何,会不会像HTTP连接那么烂!

之前就知道System.out.println()会耗资源,今天测试了一下,在Canvas中一边画文字一边打印文字,共有5461个文字,平均用时是780ms左右,而把打印全部删除后,性能明显加快,平均用时只有140ms左右,看来在开发时尽可能少用System.out.println()。

今晚看了一点Android,觉得Android和J2ME两个按钮接口(OnClickListener和CommandListener)很相似他们都带有显示界面的类,但他们获取按钮的方式有些不同。onClick(View v) 通过v.getId()获取按钮的ID,以此判断事件。而commandAction(Command c, Displayable d)可获取按钮对象或getCommandType(),判断事件。设置监听的方法则差不多,如:setOnClickListener(this) setCommandListener(this)
