Hmm...I'm not as familiar with Android, since I don't own any Android products. Does it not download, or can it not open? Did you already have a previous update of the game?
That's strange. I know for sure that many people downloaded the Android version and could play it. If anyone sees this comment, maybe they can give instructions on how to reinstall it properly.
The only other explanation I can think of is not having enough storage on your Android device. Sorry to hear about the issue!
