So having taken a look at the ketai library I found that the core.jar file which it uses is a modified one to the original, which makes sense considering that it has to have android components.
One problem though is that this still does not allow me to mix the classes together. In one jar PApplet has missing variables and therefore I cannot compile using just one or the other I would need both, with only some classes making use of certain jars.
Is this something that is doable ?
