Autostart Kodi on Boot feature?

Just asking, or requesting, or wishing…take your pick.

In SPMC there is an option to launch SPMC when the Android box is started. Here is the website…

https://github.com/koying/SPMC/wiki/How-…MC-on-boot

and the code…

To do so, create a file name xbmc_env.properties (if not existing) in the root of your external storage (normally, “/sdcard”). Add:

xbmc.autostart=yes

Now this doesn’t work for Kodi 17, but seems like it should be simple to do, or am I missing something? Or is this a possible feature in Kodi 18?
