I'm developing an Android game using Unity3d 5.6.0f3. I have Google Play Services working fine on my Galaxy S6 Edge (Android 7.0). I integrated Google Play Services using the CloudOnce plugin.
Today I bought a Galaxy Tab A 8.0 (Android 6.0.1), and it can't connect to Google Play Services in my game. logcat yields the following errors:
07-20 14:49:46.616 7622 7962 W GamesServiceBroker: Client connected with SDK 11020000, Services 11055430, and Games 37240032
07-20 14:49:46.616 7622 7962 W GamesServiceBroker: Rejecting connection - api version 6 is too high
07-20 14:49:46.616 19423 19423 V GamesNativeSDK: Play Games callback indicates connection failure.
07-20 14:49:46.616 19423 19626 I GamesNativeSDK: UI interaction required to connect to Google Play.
I downloaded Color Switch on the tablet and it was able to connect to Google Play Games, so it's an issue with my app or its configuration.
I'm not sure if "api version 6" refers to my device being on Android 6.0.1 or if that's just a coincidence. Has anybody else encountered this?
I'm happy to provide any other relevant information.
