Hey guy, I just found this raspberry Pi-like computer called the RoseApple Pi. I thought it was just another nock-off, but it actually seems pretty good. And it can run android 5.1.1, so ARC android could be used? The lack of wifi might be a problem, but if you got a compatible wifi adapter it would work.
Here's the video I saw.
And in the end, you could also get that Lemaker chip.
