在 Android Studio 等级中，重复条目：com/google/android/gms/ads/AdActivity.class

Question

我正在使用 Android Studio 开发 Android 应用。

我正在使用 google-play-services，但是当我在我的 Android 设备上运行我的应用程序时，我遇到了以下错误。

build.gradle

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "net.myApp"
        minSdkVersion 14
        targetSdkVersion 21

        multiDexEnabled true
    }

    packagingOptions{
        exclude 'com/google/android/gms/ads/AdActivity'
    }

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

dependencies {
    compile project(':facebookSDK')
    compile 'com.jpardogo.materialtabstrip:library:1.1.0'
    compile 'com.android.support:support-v4:23.4.0'
    compile 'joda-time:joda-time:2.1'
    compile files('libs/google-play-services.jar')
    compile files('libs/twitter4j-core-4.0.2.jar')

    android {
        useLibrary 'org.apache.http.legacy'
    }
}

错误

我不知道为什么 com/google/android/gms/ads/AdActivity.class 重复。

你能告诉我如何解决这个问题吗？

Answer 1

出现此错误是因为您的项目中有多个 AdActivity.class。

您可以在 build.gradle 文件中忽略其中一个。

将此添加到您的 build.gradle：

packagingOptions{
    exclude 'com/google/android/gms/ads/AdActivity.class'
}

然后构建 -> 清理，重新构建项目。
