Android开发平台是开放的平台,而位于四层框架顶端的应用开发,必然涉及到Android组件。本文将为大家详细介绍Android组件。
组件(Component),在谈及所谓架构和重用的时候,是一个重要的事情。很多时候都会说基于组件的软件架构,指的是期望把程序做乐高似的,有一堆接口标准封装完整的组件放在哪里,想用的时候取上几个一搭配,整个程序就构建完成了。
在开篇的时候就在说,Android是一个为组件化而搭建的平台,它引入所谓Mash-Up的概念,这使得你在应用的最上层,想做的不组件化都是很困难的一件事情(底层逻辑,好吧,管不了...)。具体说来,Android有四大组件四喜丸子:Activity、Service、Broadcast Receiver、Content Provider。

Android development platform is an open platform, and is located in the four story frame at the top of the application development, must involve the Android component. In this paper, we will introduce the Android component.
Component (Component), when they mention the architecture and reusable, is one of the important things. Many will say componentbased software architecture, which is expected to do the Lego like,components have a bunch of interface standard package complete put where, want to use the time take several a match, the whole programwas built.
