Service to work with players shared data?


Is there an easy way to let users to exchange/share some data?
(—In my case users are Google-Play-Games players—)
For example - players of some Game may create some mods of the Game; for example - new maps. Then players may test other players maps and to rate them, making the Game more interesting.
May be there exist some GPG or SDKBOX service? Pleeease…


  1. May be the solution is Firebase Realtime Database for Android?
  2. Is it free and code-able in Cocos (C++)?
  3. In other hand - what is the best cloud service for Cocos+Android+C++ ?


I think Firebase Realtime Database is a choose for you. It works on iOS/Android.
