在模块jetified-play-services-vision-20.0.0-runtime中发现重复的类com.go

Question

当我使用Android Studio时，会发生此错误。悲哀的我尝试了很多方法，但都不起作用。

这是错误代码。

Duplicate class com.google.android.gms.internal.vision.zze found in modules jetified-play-services-vision-20.0.0-runtime (com.google.android.gms:play-services-vision:20.0.0) and jetified-play-services-vision-common-19.1.0-runtime (com.google.android.gms:play-services-vision-common:19.1.0)
Duplicate class com.google.android.gms.internal.vision.zzf found in modules jetified-play-services-vision-20.0.0-runtime (com.google.android.gms:play-services-vision:20.0.0) and jetified-play-services-vision-common-19.1.0-runtime (com.google.android.gms:play-services-vision-common:19.1.0)
Duplicate class com.google.android.gms.internal.vision.zzg found in modules jetified-play-services-vision-20.0.0-runtime (com.google.android.gms:play-services-vision:20.0.0) and jetified-play-services-vision-common-19.1.0-runtime (com.google.android.gms:play-services-vision-common:19.1.0)
Duplicate class com.google.android.gms.internal.vision.zzh found in modules jetified-play-services-vision-20.0.0-runtime (com.google.android.gms:play-services-vision:20.0.0) and jetified-play-services-vision-common-19.1.0-runtime (com.google.android.gms:play-services-vision-common:19.1.0)
Duplicate class com.google.android.gms.internal.vision.zzi found in modules jetified-play-services-vision-20.0.0-runtime (com.google.android.gms:play-services-vision:20.0.0) and jetified-play-services-vision-common-19.1.0-runtime (com.google.android.gms:play-services-vision-common:19.1.0) 

这是build.gradle(模块：应用程序(

plugins {
id 'com.android.application'
}
apply plugin: 'com.google.gms.google-services'

android {
compileSdkVersion rootProject.ext.compileSdkVersion
buildToolsVersion "30.0.2"
defaultConfig {
applicationId "com.example.landmarkclass"
minSdkVersion 21
targetSdkVersion 30
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'com.google.android.material:material:1.2.1'
implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
testImplementation 'junit:junit:4.+'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
implementation platform('com.google.firebase:firebase-bom:26.1.0')
implementation 'com.google.firebase:firebase-analytics'
implementation 'com.google.android.gms:play-services-vision'
implementation 'com.google.firebase:firebase-ml-vision'
}

这是build.gradle项目

buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:4.1.1"
classpath 'com.google.gms:google-services:4.3.3'
}
}
allprojects {
repositories {
google()
jcenter()
}
}
ext {
compileSdkVersion = 28
supportLibVersion = "28.0.0"
}

谢谢！

(我想关注这个网站，(https://firebase.google.com/docs/ml/android/recognize-landmarks(，但会出现此错误。)

Answer 1

这是因为您同时使用播放服务ml服务和firebase ml库。如果您的要求仅此一项：https://firebase.google.com/docs/ml/android/recognize-landmarks

删除此依赖项

implementation 'com.google.android.gms:play-services-vision'

然后同步并运行。希望这能奏效。
