在android中：Context.getSystemService就使用了享元模式的原理，其实这个具体方法的实现还使用到了 装饰器模式 1.每个应用组件都可以使用系统提供的众多服务管理对象，如WallpaperManager
用户可以通过这知道系统后台发生了什么 WallpaperManagerService -> WallpaperManager 管理桌面背景的服务，深度定制化桌面系统 AppWidgetService -...PowerManager(电源服务) powermanager WindowManager(窗口管理服务) windowmanager LayoutInflater(布局服务) layoutinflater WallpaperManager...(壁纸管理器) wallpapermanager
Launcher3设置完自定义壁纸（系统自带壁纸不会记录）的时候，会在com.android.launcher3.WallpaperCropActivity.xml中记录被设置壁纸的分辨率，并提交分辨率给WallpaperManager...updateWallpaperDimensions()，它被WallpaperCropActivity.java的setWallpaper()调用； Launcher3每次旋转后会重新执行onCreate()，同时会提交当前壁纸的分辨率给WallpaperManager
如很多硬件相关的系统服务管理类和服务：ServiceManager、SensorManager、WindowManagerGlobal、WallpaperManager、AccessibilityManager
· 升级的WallpaperManager. 附加说明, 如果你的应用相提供Live Wallpapers的功能, 你必须记得增加一个 元素到你的应用manifest里面.
6.壁纸相关操作:这个不是成员变量提供的，WallpaperManager是系统Service一种，所以是SystemService提供的。
