Proguard rules

[ReGaSLZR]

Hi there!

Here's a screenshot from a crash scenario with a project with Google SignIn plugin on it. (The build is release-type and therefore needs Proguard rules.)

[EDIT: The crash happens when a user successfully logs in (via Google plugin, of course)]

So far, these are the entries on my Proguard.

-keep class com.android.* {*;}

-keep class com.unity3d.player.* { *; }
-keep class com.unity3d.plugin.* { *; }
-keep class com.unity3d.ads.** { *; }
-keep class com.unity3d.services.** { *; }

-dontwarn com.google.ar.core.**
-dontwarn com.unity3d.services.**
-dontwarn com.ironsource.adapters.unityads.**

-keep class android.* {*;}
-keep class com.android.* {*;}

-keep class com.google.* {*;}
-keep class com.google.firebase.* {*;}
-keep class com.google.googlesignin.* {*;}
-keep class com.google.android.* {*;}
-keep class com.google.android.gms.auth.* {*;}

-keep class com.google.nativelib.googlesignin.* {*;}

-keep class com.facebook.internal.* {*;}
-keep class com.facebook.unity.* {*;}

-keep class com.yasirkula.unity.* {*;}

But I feel like I'm still missing something since the logs say there's a missing method. So I come to ask, what are the exact Proguard entries for this plugin anyway? (I just guessed a bunch of them).

I just tried

-keep class com.google.android.* {*;}

instead of

-keep class com.google.android.gms.auth.* {*;}

and yet, it still is crashing.

Any updates on this, guys? I just want your input on the Proguard rules for Google SignIn (Unity SDK). 😢

I guess Google devs are busy.

I found a solution for this. Here are all the Google-related proguard rules in my project and am posting this for everyone's verification or reference:

-keep class com.google.* {*;}
-keep class com.google.impl.* {*;}
-keep class com.google.firebase.* {*;}
-keep class com.google.googlesignin.** { *; }
-keepnames class com.google.googlesignin.* { *; }
-keep class com.google.gms.** {*;}
-keep class com.google.android.gms.auth.** { *; }
-keep class com.google.android.* {*;}
-keep class com.google.unity.* {*;}

It now works on my end without crashing (on production build, proguard is turned on). In case I missed out some other important bits or there are some corrections, let me know. I just experimented on this myself.

Thanks man! you saved a life.

No problem, man! Glad to have helped. You have no idea how much pressure I got from my team when this issue was around and the Google devs were not responding at all. Still are.

can we use short template for all google classes like this?

-keep class com.unity3d.plugin.* { *; }
-keep class com.google.* { *; }

My proguard rules:-

-keep class com.unity.** { *;}
-keep class com.unity3d.plugin.* { *; }
-keep class com.google.** { *;}
