| # Ubuntu Touch / Lomiri |
| |
| Ubuntu Touch being similar to Ubuntu desktop, most features should be supported |
| out-of-the-box with SDL. |
| |
| ## Developing apps |
| |
| Ubuntu Touch apps are developed using [Clickable](https://clickable-ut.dev/). |
| |
| Clickable provides an SDL template. It is highly recommended to use the template |
| as a starting point for both new and existing apps. |
| |
| ## Considerations |
| |
| Ubuntu Touch is similar to the desktop version of Ubuntu, but presents some |
| differences in behavior. Developers should be wary of the following: |
| |
| ### SDL_GetPrefPath |
| |
| 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. |
| |
| ### Video driver |
| |
| Currently, [a bug](https://github.com/libsdl-org/SDL/issues/12247) forces SDL to |
| use the Wayland driver on Ubuntu Touch. No changes are needed in apps. |
| |
| ### Extra functions |
| |
| SDL provides `SDL_IsUbuntuTouch()` to differentiate between Ubuntu Touch and |
| regular Unix, which can help if certain platform-specific tweaks are needed. |
