Question

我从2天开始面临此问题，但仍未找到任何解决方案。我尝试更改库的版本，清理和构建项目，并使缓存无效等。

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看到的内容。

Information:Gradle tasks [:app:assembleDebug]
Error:java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex
Error:java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

我尽力了

请帮忙。
非常感谢您的时间和协助。

Answer 1

请添加此库以解决此问题

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

还要在您的应用程序类中启用multidex

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

Answer 2

您的版本有冲突

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'

隐瞒这行：

compile 'com.google.firebase:firebase-messaging:17.0.0'
compile 'com.google.firebase:firebase-core:17.0.0'
compile 'com.google.android.gms:play-services-location:17.0.0'

Answer 3

如果您正在使用3.3.0以下的Google Play服务插件，则需要使用相同版本的Firebase和Google Play服务。

如果您要使用Firebase和Google Play服务的多个版本（从版本15开始），则需要use google play service plugin 3.3.0。因此，将您的项目build.gradle更改为：

// 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:3.3.0'

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

...

最后，不要忘记总是添加以下行：

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

到应用 build.gradle的底部。

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