第一个很逗比的类

包名：android.util

类名：Config

This class was deprecated in API level 14. This class is not useful, it just returns
the same value for all constants, and has always done this. Do not use it.

这个类在API 14被弃用。这个类不是很有用,它只是返回相同的值常量,并一直这样做。^_^不要使用它。

包名：android.service.dreams

类名：梦服务DreamService

Extend this class to implement a custom dream (available to the user as a "Daydream").

Dreams
are interactive screensavers launched when a charging device is idle, or docked in a desk dock. Dreams provide another modality for apps to express themselves, tailored for an exhibition/lean-back experience.

继承这个类来实现一个自定义的梦想(用户可用“白日梦”)。

梦是交互式屏幕保护程序，启动充电设备闲置时,或在扩展坞闲置时。梦想为应用程序提供另一个形态来表达自己,专为展览/怀旧感。

说白了，就是类似pc机的屏保，安迪鲁宾逗你呢^_
