Ubuntu Touch being similar to Ubuntu desktop, most features should be supported out-of-the-box with SDL.
Ubuntu Touch apps are developed using Clickable.
Clickable provides an SDL template. It is highly recommended to use the template as a starting point for both new and existing apps.
Ubuntu Touch is similar to the desktop version of Ubuntu, but presents some differences in behavior. Developers should be wary of the following:
The only allowed writable folder is ~/.local/share/<appname>/. SDL_GetPrefPath ignores its arguments and will always return that path on Ubuntu Touch. No changes are needed in apps.
Currently, a bug forces SDL to use the Wayland driver on Ubuntu Touch. No changes are needed in apps.
SDL provides SDL_IsUbuntuTouch() to differentiate between Ubuntu Touch and regular Unix, which can help if certain platform-specific tweaks are needed.
