You can pair the camera with your Android phone and use that to do whatever.
But also, manufacturers could do apps and support APIs without adding a whole Android OS with all the downsides that it entails.
But maybe we're talking about different kind of cameras.
I have never seen camera that actually did anything useful with the pairing mode. It's inevitably buggy and useless, also requiring a manufacturer's app on the phone.
That's why it's _still_ easier to just pop the SD-card and copy files. So even Apple had to add the SD slot back to Mac Books.
