I seem to have remedied it and made the project launch on my S8 - which was the goal all along.
The process was:
- Completely clean Codeworks and Java off the machine, delete left over files, scrub registry.
- Reinstall Codeworks from UE4 - used 4.19.2, and Codeworks 1R6 (not 1R6u1). During installation, ensure to select ALL SDK installations from 19 up. My system popped multiple errors during this, but I kept clicking and eventually it installed them all and I think those errors were specific to my system.
- delete all intermediate stuff, as well as project defaults (so they reset)
- double check all plugins are only the ones being used.
- In project settings/android - set minimum to sdk to 19 - I also set target to 24 since that’s for my device.
- Build.
- Launch on device
Not sure if that really helps anyone else - but my suspicion is that 1R6 is fine for the latest 4.19 BUT, it needs all the SDK versions?
Just my guess, and don’t really know what I’m talking about, just that the above worked for me
