Error : duplicate files during packaging of APK

Question

I try to run an android eclipse on Android Studio.

I try many solutions on the internet.

But something wrong still happens

Error:duplicate files during packaging of APK /home/sam/pst-adnew/panstage/build/outputs/apk/panstage-debug-unaligned.apk
	Path in archive: lib/armeabi-v7a/libmp3lame.so
	Origin 1: /home/sam/pst-adnew/panstage/build/intermediates/exploded-aar/pst-adnew/panstage_local_library/unspecified/jni/armeabi-v7a/libmp3lame.so
	Origin 2: /home/sam/pst-adnew/panstage/build/intermediates/ndk/debug/lib/armeabi-v7a/libmp3lame.so
You can ignore those files in your build.gradle:
	android {
	  packagingOptions {
	    exclude 'lib/armeabi-v7a/libmp3lame.so'
	  }
	}
Error:Execution failed for task ':panstage:packageDebug'.
> Duplicate files copied in APK lib/armeabi-v7a/libmp3lame.so
  	File 1: /home/sam/pst-adnew/panstage/build/intermediates/exploded-aar/pst-adnew/panstage_local_library/unspecified/jni/armeabi-v7a/libmp3lame.so
  	File 2: /home/sam/pst-adnew/panstage/build/intermediates/exploded-aar/pst-adnew/panstage_local_library/unspecified/jni/armeabi-v7a/libmp3lame.so

I am working with NDK android studio..

Please help me.

I also tried the solution

packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/ASL2.0'
    }

But it does not work anymore. Please help me :(

Answer 1

In case of duplicate libraries (*.so) files, exclude option will not help as we cannot completely exclude the native binaries. There is one more option in packagingOptions. It is 'pickFirst'. We can avoid duplicate files error and include the first one the compiler encounters.

packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/ASL2.0'
        pickFirst 'lib/armeabi-v7a/libmp3lame.so'

    }

Answer 2

Include exclude 'lib/armeabi-v7a/libmp3lame.so' as well in the PackagingOption section.

packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/ASL2.0'
        exclude 'lib/armeabi-v7a/libmp3lame.so'

    }
