我在youtube上做了很多教程，但大多数都过时了，大多数语法都有变化，但即使我找到更新的教程，情况也总是如此。我按照在firebase网站中添加android的步骤操作
这是我的android\build.gradle

buildscript {
    ext.kotlin_version = '1.9.10'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.3.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.4.0'
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

这是我的应用\build.gradle
