Solution 1:

Put external fun stringFromNative(): String outside of the companion object and into the MainActivity.

Solution 2:

Kotlin :

call method from ndk file
 externalfunstringFromJNI(): String


 load c++ file
 companionobject {

            System.loadLibrary("native-lib")
        }
    }
