Hi,

SDL has a java part which i didn't build/ship, that could be the reason.

Hi,

SDL has a java part which i didn't build/ship, that could be the reason.

Would it be possible to get those working files included please? By the looks of things this project doesn't use an SDLActivity.jar so I assume it's something else going on that I would like to investigate as an alternative to using the SDLActivity route.

Thank you!
