Android 为了节省开发者撰写应用程式的时间、加速应用程式开发的速度。所以在应用程 式与内部系统环境之间设置了一个让程式更简易沟通的界面，它称之为应用程式框架 (Application framework)。 For saving the time developers spent on writing applications to accelerate applications development, a framework between applications and internal system environment is developed to simplify the communication between programs. It is called application framework. 对於应用程式的开发者来说，他得以透过Java程式呼叫应用程式框架所提供的应用程式界 面(Application Programming Interface, API)，来实作更底层的函式库(Libraries)功 能。 For the applications developer, he implements the more low-level libraries with Java programs by calling application programming interfaces provided by the application framework. 在这个应用程式框架之中，包含了活动管理者(Activity Manager)、视窗管理者(Window Manager)、内容提供者(Content Providers)、外观元件系统(View System)、程式管理者 (Package Manager)、电话功能管理者(Telephony Manager)、资源管理者(Resource Manager)、地理位置管理者(Location Manager)以及讯息管理者(Notification Manager) 等服务或者系统。 The application framework comprises Activity Manager, Window Manager, Content Provider, View System, Package Manager, Telephony Manager, Notification Manager, and other services or systems. 总体来说，开发者通常只需要理解应用程式与应用程式框架之间的运作关系、以及如何透 过Java程式语言实作的方法即可，并不太需要探究更内部的系统环境。 All in all, developers only need to understand the relations between application and the application framework and how to implement the applications by Java language; they don't need to do more research on the internal system environment. 然而，假若是要移植Android至嵌入式系统(例如洗衣机的控制界面)的产品开发者，仍有 必要理解Android系统内部的函式库、Android执行环境与Linux核心的细节。 however, for the developer who transplant Android into the embedded system (like a washing machine's control interface), he still needs to understand the Android system libraries, Android runtime environment, and the details of linux kernel. 看有没有翻得不妥需要修改的地方，thx --
