报如下错误：
Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/DEPENDENCIES
解决方案：
在project下的build.gradle下的android下或者在android下Gradle Scripts 下的 bueld.gradle(Module: app)添加
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'
exclude'META-INF/LGPL2.1'
}
