Android AGP8.1.0组件化初探

Android AGP8.1.0组件化初探

前言：

前面两篇完成了从AGP4.2到 AGP8.1.0的升级，本文是由于有哥们留言说在AGP8.0中使用ARouter组件化有问题，于是趁休息时间尝试了一下，写了几个demo，发现都没有问题，跳转和传值都是正常的，这里我也是直接从groovy转换成version-catalogs的依赖方式，由于之前升级过，所以这次很顺利，几分钟就完成了，直接上代码：

1.添加统一依赖:

[versions]
agp = "8.1.0"
androidx-espresso-core = "3.4.0"
androidx-junit = "1.1.3"
org-jetbrains-kotlin-android = "1.8.0"
core-ktx = "1.10.1"
junit = "4.13.2"
androidx-test-ext-junit = "1.1.5"
espresso-core = "3.5.1"
appcompat = "1.6.1"
material = "1.9.0"
constraintlayout = "2.1.4"
mmkv = "1.3.1"
utilcodex = "1.31.1"
arouter = "1.5.2"
arouter-compiler = "1.5.2"
org-jetbrains-kotlin-kapt = "1.8.0"[libraries]
androidx-espresso-core-3_4_0 = { module = "androidx.test.espresso:espresso-core", version.ref = "androidx-espresso-core" }
androidx-junit-1_1_3 = { module = "androidx.test.ext:junit", version.ref = "androidx-junit" }
core-ktx = { group = "androidx.core", name = "core-ktx", version.ref = "core-ktx" }
junit = { group = "junit", name = "junit", version.ref = "junit" }
androidx-test-ext-junit = { group = "androidx.test.ext", name = "junit", version.ref = "androidx-test-ext-junit" }
espresso-core = { group = "androidx.test.espresso", name = "espresso-core", version.ref = "espresso-core" }
appcompat = { group = "androidx.appcompat", name = "appcompat", version.ref = "appcompat" }
material = { group = "com.google.android.material", name = "material", version.ref = "material" }
constraintlayout = { group = "androidx.constraintlayout", name = "constraintlayout", version.ref = "constraintlayout" }
mmkv = { group = "com.tencent", name = "mmkv", version.ref = "mmkv" }
utilcodex = {group = "com.blankj",name = "utilcodex",version.ref = "utilcodex"}
arouter = {group = "com.alibaba",name = "arouter-api",version.ref = "arouter"}
arouter-compiler = {group = "com.alibaba",name = "arouter-compiler",version.ref = "arouter-compiler"}[plugins]
com-android-library = { id = "com.android.library", version.ref = "agp" }
com-android-application = { id = "com.android.application", version.ref = "agp" }
org-jetbrains-kotlin-android = { id = "org.jetbrains.kotlin.android", version.ref = "org-jetbrains-kotlin-android" }
org-jetbrains-kotlin-kapt = {id = "org.jetbrains.kotlin.kapt",version.ref = "org-jetbrains-kotlin-kapt"}[bundles]

2.添加lib-common组件配置:

@Suppress("DSL_SCOPE_VIOLATION")
plugins {alias(libs.plugins.com.android.library)alias(libs.plugins.org.jetbrains.kotlin.android)alias(libs.plugins.org.jetbrains.kotlin.kapt)
}
dependencies {implementation(libs.core.ktx)implementation(libs.appcompat)implementation(libs.material)implementation(libs.arouter)kapt(libs.arouter.compiler)testImplementation(libs.junit)androidTestImplementation(libs.androidx.test.ext.junit)androidTestImplementation(libs.espresso.core)
}kapt {arguments {arg("AROUTER_MODULE_NAME", project.name)}
}

完整配置：

@Suppress("DSL_SCOPE_VIOLATION")
plugins {alias(libs.plugins.com.android.library)alias(libs.plugins.org.jetbrains.kotlin.android)alias(libs.plugins.org.jetbrains.kotlin.kapt)
}android {namespace = "com.example.lib_cmmon"compileSdk = 33defaultConfig {//applicationId = "com.example.lib_cmmon"minSdk = 23targetSdk = 33// versionCode = 1// versionName = "1.0"testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"}buildTypes {release {isMinifyEnabled = falseproguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"),"proguard-rules.pro")}}compileOptions {sourceCompatibility = JavaVersion.VERSION_17targetCompatibility = JavaVersion.VERSION_17}kotlinOptions {jvmTarget = "17"}
}dependencies {implementation(libs.core.ktx)implementation(libs.appcompat)implementation(libs.material)implementation(libs.arouter)kapt(libs.arouter.compiler)testImplementation(libs.junit)androidTestImplementation(libs.androidx.test.ext.junit)androidTestImplementation(libs.espresso.core)
}kapt {arguments {arg("AROUTER_MODULE_NAME", project.name)}
}

3.lib-common添加ARouter初始化：

/*** @author: njb* @date: 2023/8/26 22:21* @desc:*/
public class BaseApp extends Application {@Overridepublic void onCreate() {super.onCreate();initARouter();}private void initARouter() {ARouter.openDebug();ARouter.openLog();ARouter.init(this);}
}

4.添加lib-arouter组件配置：

@Suppress("DSL_SCOPE_VIOLATION")
plugins {alias(libs.plugins.com.android.library)alias(libs.plugins.org.jetbrains.kotlin.android)alias(libs.plugins.org.jetbrains.kotlin.kapt)
}android {namespace = "com.example.lib_arouter"compileSdk = 33defaultConfig {// applicationId = "com.example.lib_arouter"minSdk = 23targetSdk = 33//versionCode = 1// versionName = "1.0"testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"}buildTypes {release {isMinifyEnabled = falseproguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"),"proguard-rules.pro")}}compileOptions {sourceCompatibility = JavaVersion.VERSION_17targetCompatibility = JavaVersion.VERSION_17}
}dependencies {implementation(libs.appcompat)implementation(libs.material)implementation(libs.constraintlayout)testImplementation(libs.junit)androidTestImplementation(libs.androidx.test.ext.junit)androidTestImplementation(libs.espresso.core)implementation(libs.arouter)kapt(libs.arouter.compiler)implementation(project(":lib-common"))
}kapt {arguments {arg("AROUTER_MODULE_NAME", project.name)}
}

5.调用ARouter初始化:

/*** @author: njb* @date: 2023/8/26 22:21* @desc:*/
public class ARouterApp  extends BaseApp {@Overridepublic void onCreate() {super.onCreate();}
}

6.主模块依赖配置：

@Suppress("DSL_SCOPE_VIOLATION")
plugins {alias(libs.plugins.com.android.application)alias(libs.plugins.org.jetbrains.kotlin.android)alias(libs.plugins.org.jetbrains.kotlin.kapt)
}android {namespace =  "com.example.writelogdemo"compileSdk = 33defaultConfig {applicationId  = "com.example.writelogdemo"minSdk = 23targetSdk = 33versionCode = 1versionName = "1.0"testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"}buildTypes {release {isMinifyEnabled = falseproguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"),"proguard-rules.pro")}}compileOptions {sourceCompatibility = JavaVersion.VERSION_17targetCompatibility = JavaVersion.VERSION_17}kotlinOptions {jvmTarget = "17"}
}dependencies {implementation(libs.core.ktx)implementation(libs.appcompat)implementation(libs.material)implementation(libs.constraintlayout)testImplementation(libs.junit)androidTestImplementation(libs.androidx.test.ext.junit)androidTestImplementation(libs.espresso.core)implementation(libs.utilcodex)implementation(libs.arouter)kapt(libs.arouter.compiler)implementation(project(":lib-arouter"))implementation(project(":lib-common"))
}

7.添加ARouter组件化配置:

7.1 引入ARouter依赖：

这里我用的是catelog方式，所以使用kapt方式

@Suppress("DSL_SCOPE_VIOLATION")
plugins {alias(libs.plugins.com.android.library)alias(libs.plugins.org.jetbrains.kotlin.android)alias(libs.plugins.org.jetbrains.kotlin.kapt)
}implementation(libs.arouter)
kapt(libs.arouter.compiler)

7.2 添加模块名称配置：

kapt {arguments {arg("AROUTER_MODULE_NAME", project.name)}
}

7.3 主模块ARouter初始化：

/*** @author: njb* @date: 2023/8/25 22:36* @desc:*/
public class LogApp extends BaseApp {private static LogApp mInstance;@Overridepublic void onCreate() {super.onCreate();mInstance = this;}public static LogApp getInstance() {return mInstance;}
}

7.4 在Activity中绑定Arouter：

ARouter.getInstance().inject(this)

7.5 添加Arouter跳转和传值：

userList = arrayListOf("年龄18","John","身高180","体重60kg","性别female")
tvText.setOnClickListener {ARouter.getInstance().build("/test/TestSplashActivity").withString("name","test张三").withSerializable("userList",userList).navigation()

7.6 test模块添加跳转路径和数据接收:

@Route(path = "/test/TestSplashActivity")
class TestSplashActivity : AppCompatActivity() {val TAG = "TestARouter"@Autowired(name = "name")@JvmFieldvar name: String = ""@Autowired(name = "userList")@JvmFieldvar mList:ArrayList<String> ?= nulloverride fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)setContentView(R.layout.activity_test_splash)ARouter.getInstance().inject(this)initView()}private fun initView() {tvName.text = "测试ARouter跳转$name"tvTextView.text = mList.toString()}
}

8.完整使用示例：

package com.example.writelogdemoimport androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.widget.TextView
import com.alibaba.android.arouter.launcher.ARouterclass MainActivity : AppCompatActivity() {private val tvText : TextView by lazy { findViewById(R.id.tvTest) }var userList:ArrayList<String> ?= nulloverride fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)setContentView(R.layout.activity_main)ARouter.getInstance().inject(this)userList = arrayListOf("年龄18","John","身高180","体重60kg","性别female")tvText.setOnClickListener {ARouter.getInstance().build("/test/TestSplashActivity").withString("name","test张三").withSerializable("userList",userList).navigation()}}
}

9.主模块布局：

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".MainActivity"><TextViewandroid:id="@+id/tvTest"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="Hello World!"app:layout_constraintBottom_toBottomOf="parent"app:layout_constraintEnd_toEndOf="parent"app:layout_constraintStart_toStartOf="parent"app:layout_constraintTop_toTopOf="parent" /></androidx.constraintlayout.widget.ConstraintLayout>

10.lib-arouter测试代码：

package com.example.lib_arouterimport android.annotation.SuppressLint
import android.os.Bundle
import android.util.Log
import android.widget.TextView
import androidx.appcompat.app.AppCompatActivity
import com.alibaba.android.arouter.facade.annotation.Autowired
import com.alibaba.android.arouter.facade.annotation.Route
import com.alibaba.android.arouter.launcher.ARouter@SuppressLint("CustomSplashScreen")
@Route(path = "/test/TestSplashActivity")
class TestSplashActivity : AppCompatActivity() {val TAG = "TestARouter"val tvName:TextView by lazy { findViewById(R.id.tv_name) }val tvTextView:TextView by lazy { findViewById(R.id.tv_test) }@Autowired(name = "name")@JvmFieldvar name: String = ""@Autowired(name = "userList")@JvmFieldvar mList:ArrayList<String> ?= nulloverride fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)setContentView(R.layout.activity_test_splash)ARouter.getInstance().inject(this)Log.d(TAG, "测试ARouter数据传递$name$mList")initView()}private fun initView() {tvName.text = nametvTextView.text = mList.toString()}
}

11.lib-arouter布局代码：

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".TestSplashActivity"><TextViewandroid:id="@+id/tv_name"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="这是Arouter测试"app:layout_constraintBottom_toBottomOf="parent"app:layout_constraintEnd_toEndOf="parent"app:layout_constraintStart_toStartOf="parent"app:layout_constraintTop_toTopOf="parent" /><TextViewandroid:id="@+id/tv_test"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginTop="30dp"android:text="这是数组"app:layout_constraintEnd_toEndOf="parent"app:layout_constraintStart_toStartOf="parent"app:layout_constraintTop_toBottomOf="@id/tv_name" /></androidx.constraintlayout.widget.ConstraintLayout>

12.日志打印如下：

13.实现效果如下：

14.遇到问题：

14.1 测试模块配置不对

由于我是直接新建的模块，所以当作完整项目配置的，这里如果只是测试组件化需要修改配置

解决方法修改libs.plugins.com.android.application为libs.plugins.com.android.library

修改完成后可以正常运行：

14.2 跳转时提示path找不到

解决方法：
a.按照上面7中的步骤配置主模块和其他组件模块,一个都不能少。

​b.同时在跳转时保证路径一致即可。

若配置完还有问题，请仔细检查每一步，直到正常跳转和数据传递，本人是亲自尝试了多个项目，基本上都没问题.

14.3 数据传递和接收问题

解决方法：

a.在kotlin中使用ARouter接收数据时需要使用@JvmField关键字

b.@Autowired(name = “name”)，name一定要和传递时一致

c.传递数组时记得序列化，接收也是一样

15.AGP8.1.0小技巧：

15.1 在没有添加统一依赖时配置:

implementation("androidx.appcompat:appcompat:1.6.1")
implementation("com.google.android.material:material:1.9.0")
implementation("androidx.constraintlayout:constraintlayout:2.1.4")
testImplementation("junit:junit:4.13.2")
androidTestImplementation("androidx.test.ext:junit:1.1.5")
androidTestImplementation("androidx.test.espresso:espresso-core:3.5.1")
implementation("com.alibaba:arouter-api:1.5.2")
kapt("com.alibaba:arouter-compiler:1.5.2")
implementation(project(":lib-common"))

15.2 添加统一依赖库配置后：

如果添加了统一的catelog配置方式后导入依赖它会自动提示，不需要开发者手动导入，这点我感觉很爽，一键一直替换，用起来简直不要太安逸了，感兴趣的同学可以自行尝试，这里就简单举例。

16.总结：

以上就是今天博客的内容在AGP8.1.0中使用组件化和遇到问题，其实本文的目的不是在于如何使用，ARouter这个很简单，相信做过组件化的同学都会，只是需要遇到问题时学会分析和调试，要不然盲目猜测是不会有结果的。开发这条路任重而道远，希望大家都能上下求索，享受这个求索的过程，痛并快乐着，也很重要，新技术出来可以尝试，也可以根据自己需要调整，不一样说非得更新用这个新技术，只要能解决问题，咋好用咋来。
