Error: Program type already present: com.google.android.gms.common.api.internal.zzb

[董維誠]

Hi

My Unity project had already imported firebase SDK, and after I imported Admob SDK and click Android Resolver at Unity then I can't build apk successfully.

the error is 

"Program type already present: com.google.android.gms.common.api.internal.zza Learn how to resolve the issue at https://developer.android.com/studio/build/dependencies#duplicate_classes."

After tested, it seems these two package have same reference with "com.google.android.gms.common.api.internal" maybe.

Because after I deleted one of them, the apk can build successfully.

But the app would crash at launch.

I read the document at "https://developer.android.com/studio/build/dependencies#duplicate_classes" and do some test, still can't solve this problem.

Hope some help.

Best Regards,
Jason

Hi

I enabled custom gradle build config to build the apk.

This is the dependencies which auto generated by Unity

And get another error description as below

D8: Type com.google.android.gms.common.internal.zzj is referenced as an interface from `com.google.android.gms.common.api.internal.zzbu`.

D8: Type com.google.android.gms.common.internal.zzj is referenced as an interface from `com.google.android.gms.common.api.internal.zzaq`.

com.android.builder.dexing.DexArchiveBuilderException: com.android.builder.dexing.DexArchiveBuilderException: Failed to process

Would you figure out something wrong?

Hi,

I discussed this to with the rest of the team and It seems that your concern is no longer related to the Mobile Ads SDK implementation.

On the other hand, we checked your plugins in Unity and found out that the plugins were using mismatch version of the prerequisite Android packages. 
To resolve this, please follow the steps below

1. In Unity, search each plugins' dependency xml (eg. GoogleMobileAdsDependencies.xml and OneSignalDependencies.xml)
2. For each <androidPackage>, Change them to the highest version if possible. More importantly, the play store packages must have matching versions
3. Force Resolve using the Play Services Resolver
4. Export the project
5. In Android Studio, check the resulting build gradle. Kindly follow the version re-matching (or updating) that Android Studio suggests for each 'implementation' / 'compile' line.

If you still encounter any issues, I would suggest to raise this to Stackoverflow to get their insights regarding your concern.
