在将vivo eclipse sdk 迁移 android studio 时候报错
Error:Execution failed for task ':vivosdk:transformResourcesWithMergeJavaResForRelease'.
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/NOTICE
File1: /Users/dsh/mobile/sdks/androidStudio/fvsdk-vivo/vivosdk/libs/httpmime-4.0.jar
File2: /Users/dsh/mobile/sdks/androidStudio/fvsdk-vivo/vivosdk/libs/apache-mime4j-0.6.jar
看起来是因为多个 jar 包里包含了同样的文件（NOTICE），导致打包时因为担心相互覆盖问题而提示出错。
解决：
android{
packagingOptions {
exclude 'META-INF/NOTICE.txt'
exclude 'META-INF/NOTICE'
}
}
