Absolutely, they could if they wanted to and they do have Android devs on staff for the Xbox app. I just get the impression there isn’t a lot of focus put on those efforts (given the state and featureset of said Android app). But, they could focus on it if they really cared about it. Problem is, it’s an unknown to the C level execs so it’s probably too risky to spend money on. Gotta keep those shareholder profits up or risk their positions.
