So… maybe I’m missing something - but there doesn’t appear to be any way to check the list of achievements on android (after connecting with Google+). I can see the achievement notifications, but I have no idea what I earned those for, and what other achievements exist.
I know what you mean. At least Plants vs. Zombies 2 has a little trophy icon on the main screen to view the achievements. Since there’s no way to view them in-game, you will need to install this app from Google: https://play.google.com/store/apps/details?id=com.google.android.play.games
