組件化架構(gòu)搭建——鋪路Android架構(gòu)師

發(fā)布時(shí)間：2023-07-03 00:06:47 作者：網(wǎng)友整理

組件化定義

組件化是建立在模塊化思想上的一次演進(jìn)，一個(gè)變種。組件化本來就是模塊化的概念。核心是模塊角色的可轉(zhuǎn)化換性，在打包時(shí)，是library；調(diào)試時(shí)，是Application。

組件化的單位是組件，這里跟模塊化的一個(gè)最大的區(qū)別就是組件之間是可以相互進(jìn)行跳轉(zhuǎn)的，其實(shí)現(xiàn)就是通過路由，這個(gè)在之后會(huì)手動(dòng)來實(shí)現(xiàn)這個(gè)路由的功能。它是一個(gè)編譯時(shí)的行為。

組件化優(yōu)點(diǎn)：

可重用
代碼簡潔
易測試

為什么使用組件化

一直使用單工程操作，項(xiàng)目越來越大導(dǎo)致出現(xiàn)了不少的問題：

查找問題慢：定位問題，需要在多個(gè)代碼混合的模塊中尋找和跳轉(zhuǎn)。
開發(fā)維護(hù)成本增加：避免代碼的改動(dòng)影響其它業(yè)務(wù)的功能，導(dǎo)致開發(fā)和維護(hù)成本不斷增加。
編譯時(shí)間長：項(xiàng)目工程越大，編譯完整代碼所花費(fèi)的時(shí)間越長。
開發(fā)效率低：多人協(xié)作開發(fā)時(shí)，開發(fā)風(fēng)格不一，又很難將業(yè)務(wù)完全分割，大家互相影響，導(dǎo)致開發(fā)效率低下。
代碼復(fù)用性差：寫過的代碼很難抽離出來再次利用。
