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

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.

 

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.

 

But its not working for new builds again

 

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.

Code (CSharp):

1. > Configure project :launcher
2. WARNING: The option setting 'android.enableR8=false' is deprecated.
3. It will be removed in version 5.0 of the Android Gradle plugin.
4. You will no longer be able to disable R8

Same problem. Did you find the solution?

 

Unfortunately, I haven't

 

i get the same error and more when i want to add level play ad from IronSource

 

I have been trying to find a solution for two months now, is this a problem in me?

 

i finally did it, for me it was a problem with androidX this video helped me

 

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.

 

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.

 

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

 

I have got the same issue and struggle a lot by changing Android sdk and JDK versions but after some days, just Enabling use R8 toggle solved my issue but i don't know how....??

 

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

 

This issue is still causing a lot of pain on the latest 2021.3.35f. Should definitely be fixed on the Unity side.

 

This works for me:
1, Tick Project Setting/Publish Settings/Custom Gradle properties Template
2, Modify Assets/Plugins/Android/gradleTemplate.properties, comment out android.enableR8 option, like:
# android.enableR8=**MINIFY_WITH_R_EIGHT**
