TokenFragment class not found error

[neurofluid]

I see that this issue continues to rear its ugly head.

What I did:

Follow directions to create and run SmokeTest. When running the compiled app on a Nexus 5X API 27 simulator and pressing 'Authenticate' I get:

Unity 5.6.4p4 64 bit running on OS X 10.13.2

Same behaviour is exhibited in my own game, but I thought I'd eliminate the obvious by trying one of the sample projects first.

Any help would be greatly appreciated.

Same error 0.9.42 Unity 2017.2.0f3, gradlebuild, use proguard

[creutzfeldt0]

I solved it!!!

If you are using 'Unity 2017','gradle build', add " -keep class com.google.games.* { ; } -keep interface com.google.games.* { ; } " to 'proguard-user.txt' file.

Thanks for the comment, @creutzfeldt0 but it didn't work for me.

I'm using 5.6.4p4 and migrating to 2017 isn't an option right now due to time constraints and refactoring that would have to be done. 5.6 doesn't have any option to manipulate the proguard file.

Right now my build process is to export to a gradle project, make some minor changes to the build.gradle file and then create the build.

Adding those changes to the proguard file (that's created in the export process) makes no difference.

The irony is that this whole exercise started due to hitting the 65K DEX limit caused when adding google play games (there are other libraries that contribute to it, but they're much more necessary than Google leaderboards to me). If I remove it, then I can just use Unity's regular build process.

Same problem, but in my case proguard is disabled. How can this be possible? log: https://gist.github.com/Deepscorn/7a471d30656024a01092ff8b3d43a463 build.gradle:

buildTypes {
    debug {
        minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-unity.txt', '../../../AndroidSources/proguard.cfg'
    }
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-unity.txt', '../../../AndroidSources/proguard.cfg'
    }
}

Resolved our issue - we've lost play-games-plugin-support.aar during git merge

Struggling with this problem for weeks now... Any advice on what to try ?
