I am waiting for SFML 2.2 to come out so that it is more stable. Part of the cmake code and the android toolchain will just get copied to tgui, so there is no use of doing that now if they are still making regular changes.

I may be able to test on an android myself eventually, but I can't test for iOS so someone else will have to help with that.

And I don't have time until July anyway, so you will have to at least wait until then.

Thank you :)

To maintain attention.

TGUI now has experimental android support.

The tutorial can be found here: https://tgui.eu/tutorials/v07/android/

TGUI now also has experimental iOS support.

I'm currently waiting for official sfml tutorials before I go ahead and finish my own tutorials though.

But since there is at least minimum support for android and ios now, I will be closing this issue.
