将C ++ AAR库添加到Android Studio中？

Question

A C++ library which was converted to .AAR (Not by me) to use with Android Studio . I was able to add the aar file inside lib folder and was able to sync successfully using gradle .

I am well aware that c++ library can be only accessed threw JNI . Unfortunate, i cant find any of C++ lib functions to include in JNI .

I am new to C++ lib integration . The arr file contains 8 .SO files

project level

      repositories {
    jcenter()
    flatDir{
        dirs 'libs'
    }
}

app level

    compile(name:'oxy', ext:'aar')

Any suggestion or help is appreciated .

While converting the .so files to aar, the author must have also written java code wrappers which actually implement the JNI interfacing. The intent would definitely be to make access to native code easier using the wrapper java classes. You could just extract the aar file using any unzipping tool and see if there is a classes.jar file. If yes, you could either decompile the .class files and see the java code (if code is not obfuscated) or you could talk to the author to get details on how to use the java classes.
