Some Android devices allow you to update the game as long as you have it installed (mine does), but if it's still not allowing you to do so you have to re-download the apk.

To get it you can use APK Downloader. However, at times the site runs out of quota so you can't use the download link generator. If that happens follow the instructions on how to install the Google Chrome extension.
