How to remove android.enableR8' from the project

Question

The option 'android.enableR8' is deprecated and should not be used anymore. It will be removed in a future version of the Android Gradle plugin, and will no longer allow you to disable R8.

Hi, I am not sure whether you have same issue as mine, this is the error I get in Console:

'> Configure project :launcher

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'

But I am able to resolve it and build my apk by follow this link (the website is in Chinese), here is the rough translate:

Tick "Custom Base Gradle Template" in [Project Setting] -> [Player]
Find “baseProjectTemplate.gradle” in your [Project File] -> Assets/Plugins/Android
change: 'com.android.tools.build:gradle:3.6.0' to 'com.android.tools.build:gradle:3.4.0'

There is picture reference at link provided.

Hope this help anyone :)

It worked for me, I'm using unity 2020.3.23f1. I did the same change, but from ¨com.android.tools.build:gradle:4.0.1¨ to ¨com.android.tools.build:gradle:3.6.0¨

This fixed every error about gradlebuild that I was having.

Thanks a lot!

Massive thank you everyone, especially ramonemmanuelalvarezsantana2! I was stuck on the same issues for days and have been trawling the internet for answers with no luck. Your suggestion fixed it.

I'm using unity 2020.3.27f1 and changed from ¨com.android.tools.build:gradle:4.0.1¨ to ¨com.android.tools.build:gradle:3.6.0¨

This fixed every error I was having too.

Thanks for making my Unity life that bit easier!

I honestly had to login just to say THANK YOU This was driving me crazy and I couldn't find ANYTHING on how to fix it!

How did you manage to run across this fix on a Chinese site?

I was getting the "'android.enableR8' is deprecated" error when targeting API level 31.

Resolved by setting "Target API Level" to "Android 11.0 (API level 30)":

Target API level

Step 02 : Set Target API Level 30 in Player Setting.

 }
 dependencies {
 // Must be Android Gradle Plugin 3.6.0 or later. For a list of
 // compatible Gradle versions refer to:
 // https://developer.android.com/studio/releases/gradle-plugin
 classpath 'com.android.tools.build:gradle:3.6.0'
 }

In my case, building for the Oculus Quest 2, it helped to switch from il2cpp to mono, build and than swtich again and it was working perfectly. Unity 2020.3.18f1.

This was the easiest solution , Thanks so much.

I was using Vuforia and was running on mono it worked, but after adding Google sign-in and adding keystore it started to show this message.

Then i read this comment after trying several tricks and i changed to IL2CPP and it worked without any errors.

I had the same problem, I tried some solutions above and did not work for me. I gave up and I turned off my computer. Next day I tried to build and it worked like nothing was wrong.
