Question Gradle Error: Configure project :launcher. The option 'android.enableR8' is deprecated

Hi,

I am having problems when compiling for Android for Quest (i´m using 2020.3.4f1). I have done a lot of research and I think there might a conflict between SDKs but i am not sure. I tried in another machine and i got the same error, so i tried to make a "Development Build" and for some reason it build fine... really strange! Then i tried again to make a normal Build but i got the same errors.

This is the first time i´ve seen this type of error so i am not sure where the problem is, although it looks like it´s coming from Android.

These are the errors i am getting:

Code (CSharp):

2. > Configure project :launcher
3. WARNING: The option 'android.enableR8' is deprecated and should not be used anymore.
4. It will be removed in a future version of the Android Gradle plugin, and will no longer allow you to disable R8.

I'm so sick of dealing with Unity, can't get anything to work. Everywhere I turn things are broken! got the android app in the tutorial to work once, then it will never work again. gradle errors, java errors, manifest errors, android studio also fails from the exported gradle. I'm uninstalling everything. why is this so bad?

 

Did you try problem 3's solution listed over here?

 

Yes, I agree. The build process for Android is a dumpster fire

Did you ever find a working solution?
