Google Play Game Services not working in Unity

Question

I created a game using Unity and now I want to add Play Services in my game. I have uploaded the game on the Google Play Store from the Console, downloaded the play services plugin from GitHub, added it in my Unity project, installed Google Play Services tools from the SDK Manager, created the achievements and the leaderboard and copied the resources to Unity. I even copied the SHA-1 from the Upload Certificate to the Google API credentials. In short, I did every solution I could find on Google. The problem is...

 private void SignIn()
     {
         Social.localUser.Authenticate((bool success) =>
         {
             if (success)
             {
                 Destroy(testObject);
             }
             else
             {
                 Destroy(testObject2);
             }
         });
     }

None of these objects are destroyed. Thanks in advance.

I found the solution. Go to your Publishing Settings tab in the Player Settings. and set the options like this.....

alt text

Then open the proguard-user.txt file and type in this....

 -keep class com.google.games.** { _; } 
 -keep interface com.google.games._* { *; }

Save it and it will surely work.

Hey, are those lines supposed to be exactly like that? with the - at the line start? I'm facing the same issue, ticking the proguard option generated two proguard-user.txt files, I pasted both lines in both of the files and saved, but now I'm stuck with build errors:

 No type signature, but name is not <fields> or *

Thanks a lot! You are really a genius! The big problem is that in the official Google Play Services documentation there is no solution to this problem. Can you please explain how this works?

Hello. This works but after showing "Connecting to Google play games", it disconnects and doesn't sign in. What can I do please?

This is the right approach, but it didn't work for me (Unity 2020.1.3f1). Adding the following to the proguard-user.txt file solved the issue for me:

  -keep class com.google.games.** { *; }
  -keep interface com.google.games.** { *; }
  -keep class com.google.unity.** { *; }
 
 -keep class com.google.android.gms.games.multiplayer.** { *; }
 -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.** { *; }

For Google Play Games to work on Android, you have to first configurate and activate PlayGames. Here's how you do it:

 PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder()
             .Build();
 PlayGamesPlatform.InitializeInstance(config);
 PlayGamesPlatform.Activate();
 PlayGamesPlatform.DebugLogEnabled = true;

And then you sign in.

How it would look in the start method:

 void Start() {
     #if UNITY_ANDROID // Only run on android, because it's not needed for iOS
     PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder()
         .Build();
     PlayGamesPlatform.InitializeInstance(config);
     PlayGamesPlatform.Activate();
     PlayGamesPlatform.DebugLogEnabled = true;
     #endif
     SignIn();
 }
 
 private void SignIn()
 {   
     Social.localUser.Authenticate((bool success) =>
     {
         if (success)
         {
             Destroy(testObject);
         }
         else
         {
             Destroy(testObject2);
         }
     });
 }

I have done all of this, but it doesn't work.

I have the same problem and I found what I did wrong. If you use the plugin, you need to use PlayGamesPlatform.Instance namespace code other than the Social. namespace code. Or the Play Games login won't even pop, yet it does pop if you check Development Build which would be confusing. Hope this would save time for those who come after me

If you use the plugin on github, change this line

 Social.localUser.Authenticate((bool success) =>

to

 PlayGamesPlatform.Instance.localUser.Authenticate((bool success) =>
