Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl. Namespace not specified.

Doesnt works for me. Can someone just add a namespace to the build.gradle?

Same issue here. Any solution?

I got the same issue :(

Downgrading to Gradle wrapper 8.2.1 helped. 8.3 does not seem to work with React Native.

I have the same issue

I had the same problem when I import opencv module.
Then I add some code to the build.gradle(opencv) file, and my problem solved:

android {
namespace 'com.example.mytestapp' // added
compileSdk 34
...

This comes up when upgrading Android Gradle Plugin to >= 8.

Updating the package to try to solve this will add two new peerDependencies from 1.14.0:
"react-native-macos": "^0.73.0",
"react-native-windows": "^0.73.0"

Why do I need to install these two when they are not used? I don't develop for windows.
And this change is breaking too, and there is no mentions/docs for the new version.
