Firebase and Google Play Game Services Won't Merge in Unity

I added the latest Firebase SDK Messaging package to my project with already well functioning GPGS. First it was possible to build the app with seemingly no issues involved but I found out GPGS stopped functioning giving me exception during initialization.

Hence I reinstalled it all. I tried to force resolve using Play Services Resolver and ended up with even more fatal problem.

Resolver gives me this error:

Same issue here. I tried updating the Resolver, removing it and adding the one provided by Firebase, and nothing works. This however seems to be a Google issue and not a Unity issue. I wrote the Firebase support and their response was "not my job" style.

 

I'm having this issue as well. Snippet of my error:

08-01 16:59:05.451 14969 14969 E AndroidRuntime: Caused by: java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/android/gms/common/api/Api$zzf;
08-01 16:59:05.451 14969 14969 E AndroidRuntime: at com.google.android.gms.auth.api.Auth.(Unknown Source)

My project ran flawlessly (running Firebase Authentication and Database, and GPGS). The moment I tried to install Google AdMob last night, everything broke.

 

What worked for me and what was my approach:

I noticed the Play Service Resolver said that there are conflicting dependencies.
I searched for Firebase related dependencies in VS and found them in Firebase > Editor > AppDependencies.xml and AnalyticsDependecies.xml.
I deleted the ones that were both in AppDependencies and in AnalyticsDependencies (deleted them in AnalyticsDependencies only)
I saved the files, Resolver kicked in and did stuff. I still got the warning of conflicting dependencies but when looking the warning to see which were conflicting the ones that I deleted were not there anymore.
I ran the game. No error. and I see Firebase messages logged.

 

thanks, the only thing that seemed to work.

 

i am stuck in strange problem..
i have admob mediation (tapjoy, vungle and adcolny)
first i integrate admob and then adcolony all works fine .. but when i try to integrate tapjoy i got a warning in console

when i build application the apk build successfully but apk crush when i open in a android device

 

@liortal can you kindly give me a little bit hint so i can deploy it on android

 

That i fix this in Unity3D and is work for my project.

Go to the
1) Assets>Editor>AppDependencies.cs and AnalyticsDependencies.cs
2) Assets>GoogleMobileAd>Editor>GoogleMobileAdsDependencies.cs
And open to edit all "com.google.android.gmslay-services" and com.google.firebase:firebase-xxx to same version But do not change the com.google.firebase:firebase-analytics-unity:version , like:
In GoogleMobileAdsDependencies.cd
<androidPackages>
<androidPackage spec="com.google.android.gmslay-services-ads:15.0.1">
<androidSdkPackageIds>
And i all change to com.google.android.gmslay-services remind is all com.google.android.gmslay-xxx :
<androidPackages>
<androidPackage spec="com.google.android.gmslay-services-ads:11.8.0">
<androidSdkPackageIds>
......
And also :
AppDependencies.cs
<androidPackages>
<androidPackage spec="com.google.android.gmslay-services-base:11.8.0">
<androidSdkPackageIds>
& com.google.firebase:firebase-common:11.8.0
But do not change : com.google.firebase:firebase-app-unity:version
.......
&
AnalyticsDependencies.cs
<androidPackage spec="com.google.firebase:firebase-analytics:11.8.0">
<androidSdkPackageIds>
But do not change : com.google.firebase:firebase-analytics-unity:version

And save all files & go to unity Force Resolve.
