gradle - Android app won't build -- The minCompileSdk (31) specified in a dependency's androidx.work:work-runtime:2.7.0-beta01

Question

I'm trying to build a project in my M1,

but I got this error when I run npx react-native run-android

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:checkDebugAarMetadata'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.CheckAarMetadataWorkAction
   > The minCompileSdk (31) specified in a
     dependency's AAR metadata (META-INF/com/android/build/gradle/aar-metadata.properties)

The error is being caused because one of your dependencies is internally using WorkManager 2.7.0-beta01 that was released today (which needs API 31). In my case it was CheckAarMetadata.kt.

You can fix it by forcing Gradle to use an older version of Work Manager for the transitive dependency that works with API 30. In your build.gradle file add:

dependencies {
    def work_version = "2.6.0"
    // Force WorkManager 2.6.0 for transitive dependency
    implementation("androidx.work:work-runtime-ktx:$work_version") {
        force = true
    }
}

This should fix it.
