Google Play Game Service: show unlocked achievement

Question

This might be a stupid question but I havent found an answer to it on Google so its up to you :)

I am using Google Play Service to provide achievements and leaderboards in my android app. I use

unlockAchievement(getResources().getString(R.string.achievement_id));

While the achivement is unlocked correctly and is shown in the achievements list it is NOT shown to the user immediately when its unlocked, i.e. the ""achievement unlocked" thingy like in the screenshot below is not beeing displayed:

Any ideas why this doesn't pop-up?

Thanks in advance!

Answer 1

I got it. I used to instanciate the GameClient in my main activity and the referenced it in the game activity. So the unlock popup was bound to the main not the game activity. So I changed

MainActivity.gamesClient.unlockAchievement(...);

to

getGamesClient().unlockAchievement(...);.

And thats it!
