Play Games doesn't work with Admob

So I try to add Play games plugin to my project but when I try to sign in the user with;

Code (CSharp):

1. Social.localUser.Authenticate(success => {  });

This error appears on Android:

AndroidJavaException: java.lang.ClassNotFoundException: com.google.android.gms.games.Games

I tried removing and re-importing play games package, installing different play games versions and force resolving but none of them worked. I tried to install Play Games into a blank project and it worked there properly. I already have admob plugin in my project so probably something wrong with it.

Any ideas?

 

I had the similar issue because I was using proguard.
If you are using proguard then don't forget to add this in proguard.txt. (location: Assets/Plugin/Android/proguard.txt)
https://github.com/playgameservices/play-games-plugin-for-unity/blob/master/scripts/proguard.txt

 

Yes, that was the problem! Thank you

 

Thanks!! you just saved me!

 

Hi, I am using these versions of unity and the plugin and I am getting the same error.
I dont use Admob though just the play services plugin.

The solution with the custom proguard does not work anymore. How I can resolve this?

• Unity version: 2021.3.2 LTS
• Google Play Games Plugin: 0.11.01

 

It looks like leaving only the Debug checkbox (On) for the minification solves the problem.

 

Im having the same issue and leaving the debug check on no longer works.
any updates for this?

 

Even I have the same problem @Steviebops

 

I found a solution, you need to have a custom proguard file, and do NOT use Force Resolve.
Use Resolve only, and the text file is this:


-keep class com.google.unity.**{*;}
-keep public class com.google.android.gms.ads.**{public *;}
-keep public class com.google.ads.**{public *;}
-keep class com.google.android.gms.games.leaderboard.** { ; }
-keep class com.google.android.gms.games.snapshot.* { ; }
-keep class com.google.android.gms.games.achievement.* { ; }
-keep class com.google.android.gms.games.event.* { ; }
-keep class com.google.android.gms.games.stats.* { ; }
-keep class com.google.android.gms.games.video.* { ; }
-keep class com.google.android.gms.games. { ; }
-keep class com.google.android.gms.common.api.ResultCallback { ; }
-keep class com.google.android.gms.signin. { ; }
-keep class com.google.android.gms.dynamic.* { ; }
-keep class com.google.android.gms.dynamite.* { ; }
-keep class com.google.android.gms.tasks.* { ; }
-keep class com.google.android.gms.security.* { ; }
-keep class com.google.android.gms.base.* { ; }
-keep class com.google.android.gms.actions.* { ; }
-keep class com.google.games.bridge.* { ; }
-keep class com.google.android.gms.common.ConnectionResult { ; }
-keep class com.google.android.gms.common.GooglePlayServicesUtil { ; }
-keep class com.google.android.gms.common.api. { ; }
-keep class com.google.android.gms.common.data.DataBufferUtils { ; }
-keep class com.google.android.gms.games.quest. { ; }
-keep class com.google.android.gms.nearby. { *; }
-keepattributes *Annotation*
-dontobfuscate

 

In my case I removed -dontobfuscate.

 

and used (2020.3.36f1):

-keep class com.google.android.gms.games.leaderboard.** { *; }
-keep class com.google.android.gms.games.snapshot.** { *; }
-keep class com.google.android.gms.games.achievement.** { *; }
-keep class com.google.android.gms.games.event.** { *; }
-keep class com.google.android.gms.games.stats.** { *; }
-keep class com.google.android.gms.games.* { *; }
-keep class com.google.android.gms.common.api.ResultCallback { *; }
-keep class com.google.android.gms.signin.** { *; }
-keep class com.google.android.gms.dynamic.** { *; }
-keep class com.google.android.gms.dynamite.** { *; }
-keep class com.google.android.gms.tasks.** { *; }
-keep class com.google.android.gms.security.** { *; }
-keep class com.google.android.gms.base.** { *; }
-keep class com.google.android.gms.actions.** { *; }
-keep class com.google.games.bridge.** { *; }
-keep class com.google.android.gms.common.ConnectionResult { *; }
-keep class com.google.android.gms.common.GooglePlayServicesUtil { *; }
-keep class com.google.android.gms.common.api.** { *; }
-keep class com.google.android.gms.common.data.DataBufferUtils { *; }
-keep class com.google.android.gms.nearby.** { *; }
-keep class com.google.unity.**{*;}
-keep public class com.google.android.gms.ads.**{public *;}
-keep public class com.google.ads.**{public *;}
-keepattributes *Annotation*

 

Is it working for you?

 

For me?

It was one of a few issues, I have it working now. FYI, I am using unity mediation, which was using admob.

 

It helped me!

Unity 2021.3.15f1 + Admob 7.3.0

Thanks
