Android: use so files from other project

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I try to use external sdk which include jar file and some *.so files. Also have sample project from eclipse which include same files in it. When I import project into android studio it works fine but when I tried to copy *.so files from imported project to my current project it cause error UnsatisfiedLinkError

Sample project target api 14, mine project target api 27. Should I inlude ndk support to my current project and recompile this *.so files or maybe is any option to use old files from sample?

You try to call a native method from your kotlin code, and expect that the implementation in the external so file will be called? It won't, because the names are different

@AlexCohn nope. I don't use directly methods from native code but library which I used need this files to works fine

1.create a folder named jniLibs under main folder, the structure is like below fig.

 |–app:

    |–|–src:

    |–|–|–main

    |–|–|–|–jniLibs

    |–|–|–|–|–armeabi

    |–|–|–|–|–|–.so Files

    |–|–|–|–|–x86

    |–|–|–|–|–|–.so Files

    ...

    |–|–|–|–|–other abi folder such as armeabi-v7a

    |–|–|–|–|–|–.so Files

place .jar file in project libs folder and add below line in module build.gradle file

dependencies {
implementation files('libs/your_own.jar')
}

All should be ok.

Edited:
some of android devices(emulator) has 64-bit processors, if your jinLibs hasn't arm64 subfolder, you could add this filters(abiFilters) to your app module’s build.gradle files:

defaultConfig {

    ...



    ndk {

        abiFilters "armeabi-v7a", "x86", "armeabi", "mips"

    }



}

this will tell app only use .so files in existing folders.
