导入 Httpclient、httpcore 和 httpmime 时出错

Question

我在 Android Studio 中遇到了这个问题。

Answer 1

将此添加到您应用的 build.gradle 文件中

    packagingOptions {
    exclude 'META-INF/DEPENDENCIES.txt'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/dependencies.txt'

}

Answer 2

正如错误消息所暗示的那样，您没有排除存在于多个依赖项中的 META-INF/NOTICE 文件

com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/NOTICE

packagingOptions {
    exclude 'META-INF/LICENSE' // will not include NOTICE file 
    exclude 'META-INF/NOTICE' // will not include NOTICE file       
}
