**我正在尝试将Firebase添加到我的android项目中，它需要以下步骤：**要使google-services.json配置值可供Firebase SDK访问，您需要Google服务Gradle插件。android studio海豚2021.3.1

将插件作为buildscript依赖项添加到项目级build.gradle文件：
根级别（项目级别）Gradle文件（/build.gradle）：

buildscript {
  repositories {
    // Make sure that you have the following two repositories
    google()  // Google's Maven repository

    mavenCentral()  // Maven Central repository

  }
  dependencies {
    ...
    // Add the dependency for the Google services Gradle plugin
    classpath 'com.google.gms:google-services:4.3.13'

  }
}

allprojects {
  ...
  repositories {
    // Make sure that you have the following two repositories
    google()  // Google's Maven repository

    mavenCentral()  // Maven Central repository

  }
}

但在我的build.gradle文件中，没有类似的内容。它几乎是空的，只有这两行：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
    id 'com.android.application' version '7.3.1' apply false
    id 'com.android.library' version '7.3.1' apply false

}

我试图回到旧版本，但它导致错误。我寻找代理设置，但我找不到任何东西。我试图禁用防火墙，并重新启动没有发生任何事情。我下载了Android花栗鼠到另一台PC，但它是游戏错误与7. 2. 2
