Android Firebase连接-渐变错误

我试图为firebase连接设置Android Studio。我按照指示行事，现在我就在这里：

所以我所做的是->添加

应用插件：“com.google.gms.google服务”

和

将'com.google.firebase:firebase core:16.0.0'

编译到模块文件中，并在项目文件中编译

classpath'com.google.gms:google services:4.0.0

。现在我看到了红色下划线，我该如何修复它

以下是build.gradle（模块：App）中的代码：

build.gradle（项目：FireBaseTest2）：

我找到了解决办法。只需更改编译和实现，它将工作

我建议您使用基于的google服务的最新版本（4.0.1）。这有助于避免进一步的错误

build.grandle：

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

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath 'com.google.gms:google-services:4.0.1'


        // 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
}

我认为这可能会帮助您复制请不要链接到代码的图像。最好将代码和错误信息复制到问题中，以便更容易阅读和搜索。我包含了代码。我理解正确吗。。。我必须手动将示例包含在错误消息中，版本与实现'com.android.support:appcompat-v7:27.1.1'相同？
