The option setting 'android.enableR8=false' is deprecated. Conflict between Admob & Firebase Plugin

Unity Services
, ,
1

I was using Admob and it was building the game fine but when I Imported the firebase plugin it give the following error:
WARNING: The option setting ‘android.enableR8=false’ is deprecated.
It will be removed in version 5.0 of the Android Gradle plugin.
You will no longer be able to disable R8

I also encountered this error when I tried to implement a leaderboard when google admob and firebase was already there, in another project.

I have tried nearly all solutions in this regard, but nothing works for me.
Such as using this solution http://answers.unity.com/answers/1859781/view.htmlhttp://answers.unity.com/answers/1859781/view.html
I need help with this.

It depends on the version of Unity you are using?

  • Check the Unity Console for any additional error messages or warnings that may provide more information about the problem.

  • Check that the correct Android SDK and JDK versions are installed on your system, and that they are correctly set up in the Unity Editor. You can do this by going to Edit > Preferences > External Tools, and checking that the correct paths are set for the Android SDK and JDK.

  • Make sure that you have the correct versions of the Google Mobile Ads and Firebase plugins for your Unity version. Check the documentation for the plugins to ensure that they are compatible with your version of Unity.

  • Try removing both the Google Mobile Ads and Firebase plugins from your project, and then re-importing them in the correct order. The correct order to import them is: Admob > Firebase
    After importing the plugins, rebuild your project and see if the issue is resolved

If the above steps do not work to resolve the issue, there are a few additional things you can try:

  • Check the “Plugins/Android/mainTemplate.gradle” file in your project’s directory. If the line “android.enableR8=false” is present, remove it and save the file.

Let me know if you have any further questions or if there’s anything else I can do to assist you with your Unity project.

Okay, So I was finally able to create my build. I did two things
First I Upgraded my project from Unity 2020 to 2021.
Secondly, I deleted the Cache C:/User/UserName/.gradle/cache folder only…

And Created the build again and it worked.

Glad to hear its working

But its not working for new builds again

6

On which version of Unity?

7

In my case (Unity 2021.3.26) ticking “Use R8” fixed the issue
Player settings > Publishing settings >Minify

I have the same issue on Unity 2021.3.29f1
I think upgrading my LTS version to a newer one was the cause but I’m not sure.

The Minify > Use R8 toggled on or off gives me errors that say it’s deprecated in both cases.

Any suggestions?

Here’s some additional error logs.

In my case (probably not for most people struggling with gradle being gradle), the solution was just to:

  • wipe anything vaguely plugin related
  • kill all gradle/java instances
  • delete c:\users\me.gradle
  • close and reopen the project (unload any .dll’s etc)

You still have to use gradle, but at least it might now work.

I uninstalled the “Mobile Notifications” (a package from Unity in the Package manager)
And set the max Android version to a lower version (Android 11.0)

Now it builds.

16

same issue:
Unity 2020.3.31
Audience Network Sdk 6.4.0

Fix:
I just imported admob sdk 8.3.0, resolved the dependencies, then built and error was gone, then I deleted admob sdk because i’m not using it. Now there are no errors in the build.

17

Don’t forget to remove resolved libraries then resolve again.

I deleted the cache file and it worked

Which cache file has to be deleted? In our .gradle folder there’s a “caches” folder with lots of stuff. Deleting it’s contents does nothing.
Also, toggling the R8 both on and off does nothing on editor version 2021.3.17f1
