库com.google.android.gms：[[15.0.1,15.0.1]]的各种其他图书馆正在请求播放服务地下室，但已解析为16.0.1

Question

同步项目时出现此错误：

com.google.android.gms库：play-services-basement正在[[15.0.1,15.0.1]]的各个其他图书馆请求，但已解析为16.0.1。

禁用插件并使用

./gradlew
  :app:dependencies

检查依赖树。

这是我的build.gradle项目文件：

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

buildscript {

repositories {
    google()
    jcenter()
    maven {
        url 'https://maven.fabric.io/public'
    }
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'
    classpath 'com.google.gms:google-services:4.1.0'
    classpath 'io.fabric.tools:gradle:1.25.4'

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

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

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

这是我的build.gradle应用程序文件：

import com.google.gms.googleservices.GoogleServicesPlugin

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

android {

defaultConfig {
    multiDexEnabled true

    vectorDrawables.useSupportLibrary = true

        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

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

我尝试过的：

• 遵循以下说明：com.google.android.gms:play-services-measurement-base is being requested by various other libraries
• 将各种库更新到最新版本

谢谢您的帮助！

更新：这是我目前在依赖项中的内容：

dependencies {
api "com.android.support:appcompat-v7:28.0.0"
api "com.android.support:customtabs:28.0.0"
api "com.android.support:support-v4:28.0.0"
api "com.android.support:cardview-v7:28.0.0"
api "com.android.support:design:28.0.0"

api ("com.google.firebase:firebase-firestore:17.1.2") {
    exclude group: "com.squareup.okhttp", module: "okhttp"
}
api ("com.firebaseui:firebase-ui-firestore:4.1.0") {
    exclude group: "com.google.code.gson", module: "gson"

    exclude group: "com.google.code.gson", module: "gson"
}
implementation fileTree(dir: 'libs', include: ['*.jar'])
}

这是我得到的错误：

这些dependencies使它建立：

dependencies {
    implementation "com.android.support:appcompat-v7:28.0.0"
    implementation "com.android.support:customtabs:28.0.0"
    implementation "com.android.support:support-v4:28.0.0"
    implementation "com.android.support:cardview-v7:28.0.0"
    implementation "com.android.support:design:28.0.0"
    implementation "com.android.support.constraint:constraint-layout:1.1.3"

    implementation "com.google.android.gms:play-services-base:16.0.1"
    implementation "com.google.android.gms:play-services-auth:16.0.1"

    implementation "com.crashlytics.sdk.android:crashlytics:2.9.5"

    implementation "com.google.firebase:firebase-core:16.0.4"
    implementation "com.google.firebase:firebase-auth:16.0.4"

    implementation ("com.google.firebase:firebase-firestore:18.0.0") {
        exclude group: "com.squareup.okhttp", module: "okhttp"
        exclude group: "com.google.code.gson", module: "gson"
        // exclude group: "com.google.guava", module: "guava"
    }

    implementation ("com.firebaseui:firebase-ui-firestore:4.1.0") {
        exclude group: "com.google.code.gson", module: "gson"
    }

    implementation ("com.firebaseui:firebase-ui-auth:4.1.0") {
        exclude group: "com.google.code.gson", module: "gson"
    }
}

我添加了customtabs:28.0.0以满足所需的版本和play-services-base:16.0.0（应该作为传递依赖获取）。也排除了重复的包，例如。 gson。使用compileSdkVersion和targetSdkVersion 28。
