Hi @ceceomer. I have exact same problem. Did you ever find a solution?

Hi @ceceomer. I have exact same problem. Did you ever find a solution?

Hi, No i didn't. I'm still waiting new version :/

I was having the same issue... i solved it by manually deleting gradle cache.

Delete the folder: _C:\Users\YOURUSER.gradle

Rebuild, and hopely enjoy!

[Nathisgreen]

Hi @macagu. I tried your suggestion (first just deleting the cache folder and then the entire .gradle folder, and running the resolver after each try) and it seems to have made no difference. Are you sure you didn't do anything else when you fixed the problem for yourself?

[macagu]

I'm sorry... i'm having the same issue again... i can't figure out what happened... maye its related to the Resolver magic?

[macagu]

Mmm... i got it working again. I'm not sure what is causing or solving this issue.

Here are the bunch of steps i've made:

• File > Build Settings > Android > Build System : Internal

• Build and Run...

• Running app, everything works fine.

• File > Build Settings > Android > Build System : Gradle

• Build and Run...

• "Resolving Dependencies..." apperared WHILE building. (maybe this is causing issues?)

• Running app, logcat errors: Unable to find gpg, DllNotFoundException: gpg, at (wrapper managed-to-native) GooglePlayGames.Native.Cwrapper.Builder:GameServices_Builder_Construct ()

• Build and Run...

• "Resolving Dependencies..." appeared while building

• Running app on device. Logcat erros: FATAL EXCEPTION: main Process: com.blabla.blabla, PID: 2250 java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/firebase/iid/internal/FirebaseInstanceIdInternal;

• Assets > Play Services Resolver > Android Resolver > Force Resolve

• Build and run...

• Running app on device. Same errors.

Trying with Android Studio...

• File > Build Settings > Android > Export Project TRUE. Export.
• Open exported project with Android Studio.
• Android Studio converted project Gradle version...
• Play from Android Studio.
• Same errors...

Back to Unity...

• Assets > Play Services Resolver > Android Resolver > Settings > Reset to Defaults

• Assets > Play Services Resolver > Version Handler > Settings > Reset to Defaults

• Assets > Play Services Resolver > Android Resolver > Force Resolve

• Console warning: Some conflicting dependencies were found. The following dependency versions were modified: com.google.android.gms:play-services-base:15.0.1 --> com.google.android.gms:play-services-base:+ com.google.firebase:firebase-analytics:16.0.1 --> com.google.firebase:firebase-analytics:+ com.google.firebase:firebase-common:16.0.1 --> com.google.firebase:firebase-common:+ com.google.firebase:firebase-core:16.0.1 --> com.google.firebase:firebase-core:+ com.google.games:gpgs-plugin-support:0.9.50 --> com.google.games:gpgs-plugin-support:+

• File > Build Settings > Android > Export Project: FALSE

• "Resolving Dependencies…" appeared.

• Console warning: Some conflicting dependencies were found.

• Build and Run.

• Running on device. Everything works fine... (for now)

I'm guessing its related to Play Services Resolver WHILE building with Gradle. Maybe files gets deleted while gradle is building? ... therefore they are not copied/included in the apk? Maybe (under some circumstances) its related to Use Gradle Daemon on Play Services Resolver > Android Resolver > Settings?

Here is my config:

• Unity 2018.2.6f1 Personal (64-bit) - Windows.
• Play Services Resolver: v1.2.84.0
• GooglePlayGamesPlugin-0.9.50
• firebase_unity_sdk_5.2.1

Hi @macagu. I appreciate the thorough reply. I have tried a bunch of the things you did and still haven't had any luck. One thing to note is the internal build wont compile for me, and tracking down what exactly the error is has proven difficult. Are you definitely getting this exact error (with the first one being Playerlevel). As there seems to be a few threads on 'GamesNativeSDK: Can't register class' but with different classes. Not sure if they are different to resolve but the other threads haven't helped me either.

[macagu]

The error i originally stumbled with was: GamesNativeSDK: Can't register class com/google/android/gms/games/Games

At first, i googled it and found many results related to GamesNativeSDK registering clases (not specially "Games"). Maybe not all these exceptions are caused by the same issue (i don't know).

So yes, maybe we are facing different issues that requires different resolutions.
