achievements

I have an Android game and I'd like to play a sound whenever a players unlocks an achievement, but I can't seem to find a way to know when the user unlocks the achievement, since most of my achievements are incremental I have no way to code it on the client side, the only way would be some callback called when the Google API shows the achievement box, but I can't find any of those on the documentation... Only thing i found was this: Integrating Google Play services achievements and android notifications @Override public void onAchievementUnlocked(final String id) { // } but I have no idea how

Many games that are created these days come with their own achievement system that rewards players/users for accomplishing certain tasks. The badges system here on stackoverflow is exactly the same.

Ideally if there is a modern tool out there that can help abstract a lot of the work in some DSL, that would be fantastic. I'm interested in seeing how others solved this issue using Ruby or Ruby on Rails. Building this from scratch

We implemented the Google Play achievements for our Android game according to the official google development documentation, but there seems to be something off, as we notice the following strange behavior in the Google Play Games app: The achievements do not show up in the Google Play Games app In the Google Play games app in the detail view of our game, the achievements tab does not show up at all: The achievements show up as an unlocked popup in game like expected when they gained via gameplay interaction, but still they do not show up in the Google Play Games app. We read that there might

Is there a way to get a user's achievements list from Xbox without dealing with screen scraping etc.? How do sites like http://www.trueachievements.com do it? (they're definitely not screen scraping as they do not have my Live ID credentials...) I know there's the Xbox LIVE Community Developer Program (XCDP) that provides some API but they do not provide achievements information as far as I can tell (links below) http://duncanmackenzie.net/Blog/put-up-a-rest-api-for-xbox-gamertag-data http://file-pasta.com/file/XML_Feeds.pdf If you want this information you can check out my new site https:/
