This is really nice, will it also be available for Android and if so what Android versions? Right now you have to install Google's physical web app thingy on Android to get beacons so it's kinda clunky and annoying. I know Eddystone was supposed to change a lot of that but I didn't see any mention of what Android versions it will work on. Is it only 5.1 and beyond or are they going to update 4.4, 5.0, etc?
