Vuforia Runtime Error on Android 9+

When I run my app on an older phone (Android 7) using the previous version Vuforia 7, there is no error, but when running on Android 9+ I get the following runtime error:

No implementation found for void com.qualcomm.vuforia.VuforiaJNI.swig_module_init()

Not sure if this is due to the older versions of Vuforia not being compatible with newer versions of Android.

Any tips on migrating to the newer Vuforia Engine 9.8/10.5 or if there is another workaround? I've tried downloading the new Vuforia package and copying the jar file over to my old project, but that hasn't worked.

Thanks!
