More than one file was found with OS independant path

[Davy Wentzler]

Once in a month or so I get myself together to try and leave Eclipse behind and try Android Studio again. Reading about the recent build performance improvements, I thought I'd try Android Studio 3.

When I build the project with com.android.tools.build:gradle:2.3.3, all is fine.

However, with com.android.tools.build:gradle:3.0.0-alpha5, my build fails with:

FAILURE: Build failed with an exception.

* What went wrong:

Execution failed for task ':AEMobileNative:transformNativeLibsWithMergeJniLibsForDebug'.

> More than one file was found with OS independent path 'lib/armeabi-v7a/libbassmidi.so'

BASS MIDI is a pre-built library with the following directory structure:

bassmidi/

bassmidi/libs/armeabi/libbassmidi.so

bassmidi/libs/armeabi-v7a/libbassmidi.so

bassmidi/libs/x86/libbassmidi.so

bassmidi/Android.mk

Android.mk contains:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := bassmidi

LOCAL_SRC_FILES := libs/$(TARGET_ARCH_ABI)/libbassmidi.so

LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include

include $(PREBUILT_SHARED_LIBRARY)

To add to the mystery, if I then click on 'Run with --stacktrace' to get more info, I get a whole different error:

Normally, I have enough experience to solve things myself, but the whole gradle and Android Studio thing remains a mystery to me, so if anyone has any pointers in the right direction, I'd appreciate it!

[Alex Cohn]

You probably specify bassmidi/libs directory explicitly in one of the build.gradle scripts, therefore armeabi-v7a/libbassmidi.so is packed into the APK twice: from its original prebuilt location and from the project build/intermediates/ndk-build. You can find the cause of duplication and eliminate it, but the easiest fix is to declare to your app/build.gradle

android {
  packagingOptions {
    pickFirst 'lib/armeabi-v7a/libassmidi.so'

pickFirst 'lib/x86/libassmidi.so'

}

}

Hi Alex,

No, I have no knowledge on gradle, so I did not enter this. Note that with gradle 2.3.3 it works fine. Originally, the project has been imported by converting automatically from the Eclipse project(s).

The pickFirst did not work. Note that no path exists in my structures that start with lib/armeabi-v7a. There is a libbassmidi.so in src\main\jni\bassmidi\libs\armeabi-v7a, src\main\jniLibs\armeabi-v7a, build\intermediates\jniLibs\debug\armeabi-v7a and

build\intermediates\ndkBuild\debug\obj\local\armeabi-v7a

[Alex Cohn]

Thanks for clarification. You probably can delete the src\main\jniLibs directory altogether, and gradle will just work.

BR, 

Alex

[Davy Wentzler]

Thanks, that did it!!

Not that it builds now, but that is not related to the NDK at least.

[Ajay Saini]

Thanks it worked!!
