将 firebase 依赖项添加到 android 应用程序时，应用脚本 build.gradle 错误

Question

I am adding firebase to my android application. After adding dependecies classpath 'com.google.gms:google-services:4.3.0' and implementation 'com.google.firebase:firebase-database:18.0.1' and plugins that is apply plugin: 'com.google.gms.google-services' and trying to sync it brings an "Apply script build.gradle" error

I have updated my google repositories and have a good internet connection

apply plugin: 'com.google.gms.google-services' 

dependencies {
        classpath 'com.android.tools.build:gradle:4.2.1'
        classpath 'com.google.gms:google-services:4.3.0'}`
dependencies{implementation 'com.google.firebase:firebase-database:18.0.1'}

I expected a successful sync after adding the dependencies and applying plugins but an error occured

Answer 1

Check the doc:

To setup firebase you have to configure the top-level build.gradle file with:

buildscript {

  repositories {
    // Check that you have the following line (if not, add it):
    google()  // Google's Maven repository
  }

  dependencies {
    // ...

    // Add the following line:
    classpath 'com.google.gms:google-services:4.3.0'  // Google Services plugin
  }
}

allprojects {
  // ...

  repositories {
    // Check that you have the following line (if not, add it):
    google()  // Google's Maven repository
    // ...
  }
}

Then in your app/build.gradle :

apply plugin: 'com.android.application'

android {
  // ...
}

dependencies {
  // ...
  implementation 'com.google.firebase:firebase-database:18.0.1'

}

// Add the following line to the bottom of the file:
apply plugin: 'com.google.gms.google-services'  // Google Play services Gradle plugin

To complete the setup of the google play services plugin you have to

• add the google-services.json file.

For Latest android studio, you can add library like below

plugins {
    id 'com.android.application' version '7.2.0' apply false
    id 'com.android.library' version '7.2.0' apply false
    id 'org.jetbrains.kotlin.android' version '1.6.21' apply false
    id 'com.google.dagger.hilt.android' version '2.43.2' apply false
    id 'androidx.navigation.safeargs.kotlin' version '2.4.1' apply false

    
    id 'com.google.gms.google-services' version '4.3.10' apply false 
    id 'com.google.firebase.crashlytics' version '2.8.1' apply false
}

settings.gradle

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
        jcenter()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        jcenter()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}
rootProject.name = "GameShow"
