Version Conflicts between Firebase Analytics Unity Package and the Google Mobile Ads Unity Package.

[Jamie Corkhill]

Hello. I posted this on the Google Mobile Ads SDK Google Group, but I wanted to post it here as well for it also concerns Firebase Analytics, and may be helpful for someone in the future.

I have been attempting to implement the latest version of Google Analytics for Firebase, version 5.4.0, as well as the Google Mobile Ads SDK, version 3.15.1, in my Unity Project, with an Android Build Target.

Even after updating the Android Play Services Resolver plugin to its latest version, 1.2.95.0, I still receive the following warning in the Unity Console:

Some conflicting dependencies were found.

The following dependency versions were modified:

com.google.android.gms:play-services-ads:15.0.1 --> com.google.android.gms:play-services-ads:+

com.google.firebase:firebase-analytics:16.0.4 --> com.google.firebase:firebase-analytics:+

com.google.firebase:firebase-common:16.0.3 --> com.google.firebase:firebase-common:+

com.google.firebase:firebase-core:16.0.4 --> com.google.firebase:firebase-core:+

Additionally, when trying to build the APK for Android, I receive the following error:

CommandInvokationFailure: Gradle build failed. 

C:/Program Files/Java/jdk1.8.0_161\bin\java.exe -classpath "C:\Program Files\Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-4.2.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx2048m" "assembleRelease"

The main problem is:

Any help would be much appreciated.

Thank you,

Hi Jamie,

Sorry for the delay in getting back to you.  A real fix for this issue is in the works, but as a workaround for the time being, you can edit Assets/Firebase/Editor/AnalyticsDependencies.xml, adding in:

    <androidPackage spec="com.google.android.gms:play-services-measurement-sdk-api:16.0.3">
    </androidPackage>  

along side the other androidPackages listed in there.  You'll still see that warning, but you should be able to build with that.

We'll update this when a proper fix is made available.

Hi Umair,

It seems like there is some issue with the interaction between Firebase Analytics and the Google Mobiles Ads SDK.  We are still trying to get a proper fix for it, but from https://github.com/firebase/quickstart-unity/issues/241, some other users have found that using release 5.3.1 has worked for them, which you can get via https://dl.google.com/firebase/sdk/unity/firebase_unity_sdk_5.3.1.zip

We are working on an update that will have the proper fix, but in the meantime that might work for you.
