If anyone can help with this it would be much appreciated.

This looks like the plugin author modifed engine (FJavaWrapper in AndroidJNI.h) to make the plugin work and you haven’t applied the same changes and rebuilt the engine. The plugin should be redone to remove dependency on modifying the engine.
