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):
1. Starting a Gradle Daemon, 1 incompatible Daemon could not be reused, use --status for details
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.
5. Exception while marshalling C:\Program Files\Unity\Hub\Editor\2020.3.4f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\build-tools\28.0.3\package.xml. Probably the SDK is read-only
