android - 将 Firebase 添加到我的 Android 项目时出错

问题描述

我正在将 Firebase 添加到我的应用程序中，以使用 Crashlytics。很好，但是当我按照官方指南安装它时，我从 Gradle 收到错误，即找不到谷歌播放服务。为什么它告诉我找不到？

我的应用程序正在运行最新的 Gradle“v3.4.1”，我搜索了这个问题，得到了这个答案：

因此，作为快速修复，我添加了另一个存储库，其中包含：

repositories {
    maven { url 'https://dl.bintray.com/android/android-tools' }
}

链接：错误：找不到 com.google.gms:google-services:4.2.0

但这对我没有帮助，仍然没有找到错误。

这是我的 Gradle 配置文件：

项目等级：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'
        // Check for v3.1.2 or higher
        classpath 'com.google.gms.google-services:4.2.0'

        // Add dependency
        classpath 'io.fabric.tools:gradle:1.29.0'


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

allprojects {
    repositories {
            google()
            jcenter()
            maven { url "https://jitpack.io" }
    }
}

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

来自 Gradle 的错误：

解决方案

因为 google-services:4.2.0 在 Central Repository 不可用，所以需要从 Android Tools Repository 下载。要将其添加到您的项目中，请将其添加到构建脚本存储库。有关更多信息，请参阅https://mvnrepository.com/artifact/com.google.gms/google-services/4.2.0

buildscript {
    repositories {
        jcenter()
        google()
        maven {
            url 'https://maven.fabric.io/public'
        }
        //  Add this to your project 
        maven { url 'https://dl.bintray.com/android/android-tools' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.2.0'

        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.8.4'
        classpath 'com.github.dcendents:android-maven-gradle-plugin:2.1'
        // These docs use an open ended version so that our plugin
        // can be updated quickly in response to Android tooling updates

        // We recommend changing it to the latest version from our changelog:
        // https://docs.fabric.io/android/changelog.html#fabric-gradle-plugin
        classpath 'io.fabric.tools:gradle:1.27.0'
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
        }
        google()
    }
}

在您的应用级构建文件中，Google-service 插件移至底部。

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