android - 在模块classes.jar中找到重复的类android.support.v4.app.NotificationCompat$Action$Extender (com.android.support :support

Question

我收到多行错误，指出它有重复的类

Duplicate class

android.support.v4.accessibilityservice.AccessibilityServiceInfoCompat found in modules classes.jar (com.android.support:support-compat:28.0.0) and classes.jar (com.android.support:support-v4:24.0.0) Duplicate class android.support.v4.app.ActionBarDrawerToggle found in modules classes.jar (com.android.support:support-core-ui:28.0.0) and classes.jar (com.android.support:support-v4:24.0.0) Duplicate class Go to the documentation to learn how to Fix dependency resolution errors.

我的 gradle.app 具有如下依赖项:

dependencies {

    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.google.android.gms:play-services:10.2.4'
    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'

}

您需要升级版本，可以通过使用序列 Alt+Enter 来完成此操作:

现在您不需要使用所有 Google Play 服务，只需使用模块、示例即可:

implementation 'com.google.android.gms:play-services-ads:VERSION'
implementation 'com.google.android.gms:play-services-auth:VERSION'
implementation 'com.google.android.gms:play-services-gcm:VERSION'

但如果您确实需要使用 'com.google.android.gms:play-services:VERSION'，为了避免重复的类，请在 app/build.gradle 中使用此配置 文件:

implementation ('com.google.android.gms:play-services:10.2.4') {
    exclude group: "com.android.support", module: "support-v4"
}
