Originally posted by pimpim There are some open source projects that use the fact that it's Android to deploy custom feature packages for some Sony cameras, eg the a5000, nex 6 etc. Probably also early a7 models. This is different than Samsung's android cameras, updates or access to a store are supposed to be hidden to the user.
If you like doing funky stuff with cameras try a sony a5000 or nex-5r, they're cheap and you can log in via telnet over wifi and mess around, enable clean hdmi etc. Look for ma1co openmemories on github.
I wonder about magiclantern for canon. It seems to not replace the OS but it's sort of a layer on top of it.
At one time I programmed digital radios. We used a “middle ware” that came between the ap and the o/s, so we could install the ap on any o/s, as long as there was “middle ware” for that o/s. Write the middle ware once, then install as many aps as you wanted.
