Online multiplayer game using Google Play Games Services in Cocos2D-X

After 6 months I was back to my project, but…
When installing then starting 6 months old apk - I still could connect to GooglePlay.
But compiling the same apk I get E TokenRequestor: You have wrong OAuth2 related configurations.

Then I’ve found my debug.keystore file was changed/updated; seems it been auto-updated every 365 days.
(after adding new/updated SHA-1 signing-certificate fingerprint in OAuth 2.0 client IDs I can connect again :slight_smile: )

I would say to have a single realtime event listener class that will pass the data in the callbacks to the appropriate controller classes using events or directly, instead of having two separate real time event listeners. My solution uses a NetworkController class to send and receive any data over the wire and it acts as a service layer to my game engine.

Here is the .h file for my NetworkController, hope it helps.

class NetworkController : public GameServiceInterface, public gpg::IRealTimeEventListener {
public:
  NetworkController();
