mobile – Where does a native *.so library and its headers go in an android project? – Stack Overflow

Questions:

I have looked at Use prebuilt JNI library in Android Studio 3.1 and How to use .so in a second project in Android?. The first is trying to get a library file without headers working and the other seems to be focusing on a specific issue with his build (although there’s some useful information there). I’m relatively new to app development and especially to native development on android. I’ve gotten a build with the JNI library and some c++ code working, but that seems to be just for building from source.

It’s probably a simple answer, but I haven’t been able to find documentation on this specifically in the android developers documentation. I’m interested in understanding the correct (or most conventional) place to put and way to use a precompiled library (module/lib/*.so and module/include/*.h) in an android project. Would I even need to use JNI or the NDK if the library is built with another build tool?

For some context, I’m trying to work with the essentia library. I have followed the guide on compiling for Android and have a build with the general hierarchy mentioned above (essentia/lib and essentia/include) that seems to be working.
