Is there a way to don't include .so file if I use created ndk lib?

问题

I created Android lib that use NDK ArCore

https://developers.google.com/ar/develop/c/enable-arcore

Then I built a lib and got .aar file. Then I created new sample project and included this .aar file like a module (import .JAR/.AAR package) and linked it like dependency, so all works fine.

Issue is - when I try to call method that use ArCore I am getting such error

E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.example.ar, PID: 7822

In order to fix it: After I build my lib there are some autogenerated files under build dir, there I found arcore-native dir and there four dirs

I just moved this source to my sample project under the main dir and now it is completely works

Question is - is there is a way to don't include this dirs with .so files in project when implementing the lib? Maybe I need to include them directly to lib somehow?

P.S. Because it is a little bit hard everytime ask user that want to implement my lib also include a few dirs with .so files...

回答1:

You can put the .so files from arcore-native in your .aar file and they will be delivered with your lib.
