Android 组件化

一、gradle配置,组件化第一步需要规范自己项目的gradle写法
1.项目根目录创建config.gradle

//添加自定义属性
ext {
   //生产/开发环境  false组件化环境   true集成化开发环境
   isRelease = false

   url = [
         "release":"http://release",
         "debug":"http://debug"
   ]

   androidId = [
           compileSdkVersion:29,
           buildToolsVersion:"29.0.3",
           minSdkVersion:24,
           targetSdkVersion :29,
           versionCode :10,
           versionName :"1.1.0"
   ]

   appId = [
           "app":"com.hxdl.coco",
           "demo":"com.hxdl.coco.demo",
           "test":"com.hxdl.coco.test"
   ]
   dependencies  = [
            "appcompat": "androidx.appcompat:appcompat:1.1.0",
            "constraint": "androidx.constraintlayout:constraintlayout:1.1.3"
            "recyclerview": "androidx.recyclerview:recyclerview:1.1.0",
            "cardview":"androidx.cardview:cardview:1.0.0",
            "kotlin": "org.jetbrains.kotlin:kotlin-stdlib:1.3.61",
             ...
   ]
}

2.引用config.gradle ，项目根gradle添加

apply from: "config.gradle"

为每个moudle gradle 配置引用config配置参数做统一化修改
主Module

def androidId = rootProject.ext.androidId
def appId = rootProject.ext.appId
def support = rootProject.ext.dependencies
 defaultConfig {
        applicationId appId.app
        minSdkVersion androidId.minSdkVersion
        targetSdkVersion androidId.targetSdkVersion
        versionCode androidId.versionCode
        versionName androidId.versionName
        ...
    }
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

    if(isRelease){
        implementation project(':demo')
        implementation project(':test')
    }
    support.each { k , v -> implementation v}
}

其他moudle

if(isRelease){
   apply plugin: 'com.android.library'
}else {
   apply plugin: 'com.android.application'
}
def androidId = rootProject.ext.androidId
def appId = rootProject.ext.appId
android {
    compileSdkVersion androidId.compileSdkVersion
    buildToolsVersion androidId.buildToolsVersion
    defaultConfig {
        if(!isRelease) {
            applicationId appId.demo
        }
        minSdkVersion androidId.minSdkVersion
        targetSdkVersion androidId.targetSdkVersion
        versionCode androidId.versionCode
        versionName androidId.versionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    ...

以上gradle配置 isRelease 为true 集成化环境 false 为组件化开发环境每个module可以独立运行
isRelase控制gradle的动态配置是否是作依赖库还是作为直接可运行的Moudle
support.each { k , v -> implementation v} 为grdle循环遍历语法依赖config所配置的第三方依赖库
三、Module之间的通信
使用阿里的ARounter进行Mudle之间页面的跳转和通信https://www.jianshu.com/p/6021f3f61fa6
这样组件化的模型就基本搭建完成
