Play-games-plugin-for-unity: Could not register one or more required Java classes.

Created on 18 Sep 2016 · 6Comments · Source: playgameservices/play-games-plugin-for-unity

Hi! When Ive updated Unity to 5.4 (last update 5.4.0p4) and Play Games Plugin to 0.9.34, my app cant connect to Google Play Games. GamesNativeSDK logs:

E/GamesNativeSDK(26739): Can't register class com/google/android/gms/games/multiplayer/ParticipantResult: an exception occurred.

E/GamesNativeSDK(26739): Can't register class com/google/android/gms/nearby/connection/AppIdentifier: an exception occurred.

E/GamesNativeSDK(26739): Can't register class com/google/android/gms/nearby/connection/AppMetadata: an exception occurred.

E/GamesNativeSDK(26739): Could not register one or more required Java classes.

Thats it. Ive tried everything - removed plugin, updated all libs in Android SDK Manager, removed Android/libs from project, imported plugin to the clean project. But nothing good for me!

All the time console logs this errors, which are above.

Could somebody help me?

Absolutely the same problem. Occures just after PlayGamesPlatform.Instance.Authenticate invokation.
Any solutions?

I found it strange that only play-services-games & play-services-nearby libs were upgraded to 9+ version but not play-services-base & play-services-basement (they are 8.4). I tried to force their upgrade via manual replacement in Plugin/Android folder. It helped a little and authorization stage was passed but crashed somewhere later. Probably the crash was just specific for my project

All the .aar files need to be the same version. The new version of the plugin 0.9.35, contains an updated resolver which will work much better.

Disable minification in player settings. It worked for me. It is probably a proguard issue. I think some proguard keep rules are needed for this plugin.
