android - 使用 com.google.gms 时出错：google-services: 4.3.4

问题描述

我正在尝试将 Firebase 项目连接到我的应用程序。但是当我添加 "classpath" com.google.gms: google-services: 4.3.4" AS 时出现此错误：

原因：无法找到请求目标的有效认证路径

我应该怎么办？

构建.gradle：

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

 buildscript {
repositories {
    google()
    jcenter()
}
dependencies {
    classpath "com.android.tools.build:gradle:4.0.1"
    classpath 'com.google.gms:google-services:4.3.3'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}

allprojects {
    repositories {
        google()
        jcenter()
}
}

 task clean(type: Delete) {
 delete rootProject.buildDir
 }

构建.gradle（应用程序）：

 android {
compileSdkVersion 30
buildToolsVersion "29.0.3"

defaultConfig {
    applicationId "com.vogella.findpeople"
    minSdkVersion 14
    targetSdkVersion 30
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

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


 dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.1'
implementation 'androidx.annotation:annotation:1.1.0'
implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'
testImplementation 'junit:junit:4.13'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'


implementation 'com.google.firebase:firebase-auth:19.4.0'
implementation 'com.google.firebase:firebase-database:19.5.0'
}

解决方案

我标记的链接应该适合你。尝试这个

classpath 'com.google.gms:google-services:4.3.3'

用这个替换你的类路径并重新同步。
