java - 错误多个 dex 文件定义了 Lcom/google/android/gms/location/places/zza；

Question

我已经遇到这个问题两天了，仍然没有找到任何解决方案。我尝试更改库的版本、清理和构建项目以及使缓存无效等。

下面是我的 build.gradle 文件:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.root.ambulancetracking"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }

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


dependencies {
    //noinspection GradleCompatible
    implementation 'com.google.android.gms:play-services-maps:15.0.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:27.1.1'
    compile 'com.mcxiaoke.volley:library-aar:1.0.0'
    compile 'com.android.support:support-v4:27.1.1'
    compile 'com.android.support:design:27.1.1'
    compile 'com.android.support:recyclerview-v7:27.1.1'
    compile 'com.android.support:cardview-v7:27.1.1'
    compile 'com.google.firebase:firebase-messaging:17.0.0'
    compile 'com.google.firebase:firebase-core:16.0.0'
    compile 'com.google.android.gms:play-services-location:15.0.1'
    compile 'com.google.code.gson:gson:2.8.0'
    compile 'com.github.ar-android:DrawRouteMaps:1.0.0'
}
apply plugin: 'com.google.gms.google-services'
configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '25.3.1'
            }
        }
    }
}

下面是 build.gradle(项目):

// 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:3.0.1'
        classpath 'com.google.gms:google-services:3.2.0'

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

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

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

这是我在消息窗口中收到的内容。

我已经尽力了

请提供任何帮助，我们将不胜感激。
非常感谢您在此事上花费的时间和提供的帮助。

请添加此库来解决此问题

implementation 'com.android.support:multidex:1.0.3'

另外，在您的应用程序类中启用 multidex

    @Override
    public void onCreate() {
        super.onCreate();
        MultiDex.install(this);
  }
