🐛 Caused by: groovy.lang.MissingPropertyException: Could not get unknown property 'android' for task ':react-native-vision-camera:jitsiAndroidSourcesJar' of type org.gradle.api.tasks.bundling.Jar.

What were you trying to do?

I wanted to show the camera preview on the Android platform and facing some build issue
on iOS it's working fine

Reproduceable Code

Install the Library adding manual installation step

include ':react-native-vision-camera'
project(':react-native-vision-camera').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-vision-camera/android')

in settings.gradle file

What happened instead?

The app is throwing build issues on Android studio Arctic fox

project info

buildToolsVersion = "30.0.3"
compileSdkVersion = 31
minSdkVersion    = 23
targetSdkVersion = 31
supportLibVersion = "28.0.0"

Please share both of your build.gradle files.

Compressed_build_files.zip
@mrousavy Please check ZIP i have shared both of them

[mrousavy]

Hey - I'm not downloading/opening .zip files from an untrusted source. Please share them via code snippets here (```).

Also, make sure to compare your files with the RN Template (https://github.com/facebook/react-native/blob/main/template/android/app/build.gradle) to make sure you didnt remove anything critical. From the error message it looks like something like project.ext.react = [ ... is missing in yours
