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

Question

我从 2 天开始就面临这个问题，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，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得到的内容。

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，任何帮助将不胜感激。
非常感谢您在这件事上的时间和帮助。

Answer 1

请添加此库以解决此问题

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

此外，在应用程序类中启用 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'

隐蔽到这句台词：

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

如果您使用的是低于 3.3.0 的 Google Play 服务插件，则需要使用相同版本的 Firebase 和 Google Play 服务。

如果你想使用多个版本的Firebase和Google Play服务(从版本15开始(，你需要使用Google Play服务插件3.3.0。因此，请将项目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，不要忘记始终添加以下行：

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

到您的应用程序构建.gradle的底部。
