使用Cxense Android版SDK” ,我收到重复类的消息:

Duplicate class android.support.v4.app.INotificationSideChannel found in modules classes.jar (**com.android.support:support-compat:27.1.1**) and classes.jar (**com.android.support:support-v4:22.2.0**)
Duplicate class android.support.v4.app.INotificationSideChannel$Stub found in modules classes.jar (com.android.support:support-compat:27.1.1) and classes.jar (com.android.support:support-v4:22.2.0) 
Duplicate class android.support.v4.app.INotificationSideChannel$Stub$Proxy found in modules classes.jar (com.android.support:support-compat:27.1.1) and classes.jar (com.android.support:support-v4:22.2.0) 
Duplicate class android.support.v4.app.ListFragment found in modules classes.jar (com.android.support:support-fragment:27.1.1) and classes.jar (com.android.support:support-v4:22.2.0) 
Duplicate class android.support.v4.app.ListFragment$1 found in modules classes.jar (com.android.support:support-fragment:27.1.1) and classes.jar (com.android.support:support-v4:22.2.0) 
Duplicate class android.support.v4.app.ListFragment$2 found in modules classes.jar (com.android.support:support-fragment:27.1.1) and classes.jar (com.android.support:support-v4:22.2.0) 
Duplicate class android.support.v4.app.LoaderManager found in modules classes.jar (com.android.support:support-fragment:27.1.1) and classes.jar (com.android.support:support-v4:22.2.0) 

这是我的应用程序级别 build.gradle 配置:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.tototita.cxensetestapp"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

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


    packagingOptions {
        exclude 'META-INF/LICENSE'
    }
    compileOptions {
        sourceCompatibility = '1.8'
        targetCompatibility = '1.8'
    }


}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.1' 
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

     //**CXsense
     implementation 'com.cxpublic:cxense-android:1.0.1'
}

如何避免Cxense SDK中肯定包含这些重复的类?

答案 0 :(得分:2)

如果有重复项,请使用exclude

implementation ('com.cxpublic:cxense-android:1.0.1') {
    exclude group: "com.android.support", module: "support-v4"
}

或以implementation 'com.android.support:appcompat-v7:27.1.1'的名义删除support-v4

答案 1 :(得分:1)

有两种方法可以解决您的问题。

  1. 排除重复的依赖项,而implementation 分别

  2. 通用方式从每个implementation中排除重复的依赖项

让我们首先了解这个问题:

在这种情况下,工件 com.android.support 是重复的,因为您的 app模块使用的版本是 27.1.1 工件 com.cxpublic:cxense-android:1.0.1 的内部依赖性为 com.android.support 使用版本: 22.2.0

因此,您应该手动删除其中之一(建议删除旧版本或较低版本)。让我们尝试将其删除!


第一种方法:

implementation ('com.cxpublic:cxense-android:1.0.1') {
    exclude group: "com.android.support", module: "support-v4"
}
在我们的工件com.android.support中为 com.cxpublic:cxense-android:1.0.1

放入排除不会为 { {1}} 库,当我们在此工件上使用实现时。

因此,可以通过手动将此块放置到每个有此冲突的工件来解决问题。

通过第二种方式:

我们可以删除包含的依赖项,并用具有最新编号的软件包替换它们。在我们的情况下,它是 support-v4 ,具有不同的版本。因此,转到应用程序级别 build.gradle 的android块,并将其放在该块的下面,以从所有工件中删除重复的 support-v4 ,以便我们可以将依赖性。
