The Android answer to Apple's Game Center
app on iOS will be Google Play Games, according to information obtained by Android Police
from a Play Services APK teardown. The service will bring lobbies and invites for matchmaking, in-game chat, cloud game saves, achievements and leaderboards to the platform for developers to make use of.
The APK Android Police pulled apart is a file package primarily used to update Android apps, so this update was riddled with code that indicated what features would be coming to the platform down the road, but aren't accessible just yet. There is certainly a good chance Google Play Games will be fully unveiled at Google's I/O event next week in San Francisco.
