Building an Android OS based on a multiplayer game with libGDX

I am trying to create a turn based multiplayer card game and I used libGDX to create my game environment. I know this framework does not use google-activities, however I am now having problems with the google-play API for turn-based play.

It seems you MUST have actions as the API returns intent values ​​(for fetching games, inviting players, and handling invitations).

• Has anyone managed to create turn based games using libGDX and google-play?
• Is there a better way I could use besides google-play? My game is not very difficult and just involves players picking one card from a deck that damages another player. I like the idea that users can have multiple games and be "offline" before their turn.
