如何消除"请在构建文件底部应用google-services插件"警告

我的应用运行正常，但需要移除以下警告：
Please apply google-services plugin at the bottom of the build file.
已尝试将Gradle更新至7.5版本，问题仍未解决。

当前配置文件 #

Project级build.gradle #

// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
    id 'com.android.application' version '7.4.1' apply false
    id 'com.android.library' version '7.4.1' apply false
    id "com.google.gms.google-services" version "4.3.14" apply false
}

App级build.gradle #

plugins {
    id 'com.google.gms.google-services'
    id 'com.android.application'
}

android {
    namespace 'com.ahmedapps.walkthrough_app'
    compileSdk 33

    defaultConfig {
        applicationId "com.ahmedapps.walkthrough_app"
        minSdk 21
        targetSdk 33
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_16
        targetCompatibility JavaVersion.VERSION_16
    }
}

dependencies {

    implementation 'androidx.appcompat:appcompat:1.6.1'
    implementation 'com.google.android.material:material:1.8.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'

    androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.1'

    implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.1.0"

    implementation "com.airbnb.android:lottie:$lottieVersion"

    implementation platform('com.google.firebase:firebase-bom:31.2.2')
    implementation 'com.google.firebase:firebase-analytics'

    implementation 'androidx.core:core-splashscreen:1.0.0-alpha01'

    implementation 'com.facebook.android:audience-network-sdk:6.12.0'
    implementation 'com.google.android.gms:play-services-ads:21.5.0'
    implementation 'com.google.ads.mediation:facebook:6.12.0.0'

    implementation 'com.onesignal:OneSignal:[4.0.0, 4.99.99]'
}

解决方案 #

警告的核心原因是Google Services插件需要在Android应用插件之后加载，且必须是plugins块中的最后一个插件。调整App级build.gradle的plugins顺序即可解决：

修改后的App级build.gradle plugins块：

plugins {
    id 'com.android.application'
    id 'com.google.gms.google-services'
}

原理 #

Google Services插件需要读取Android插件配置的applicationId、buildTypes等信息来生成Firebase相关的配置文件，因此必须在Android插件初始化完成后再加载，放在plugins块末尾能确保它是最后执行的插件，避免因依赖未初始化导致的警告。
