Android Studio build problem: Task :app:checkDebugAarMetadata FAILED

Issue

I just created a new Android Studio project, placed two buttons and wanted to run the app. But it didn't work out like the last time and threw these error messages:

´´´ 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 One or more issues found when checking AAR metadata values:

I also uninstalled Android Studio, but it didn't work. Does anyone know what to do? I'm pretty new to Android Studio and Gradle. Thank you!

Solution

The minCompileSdk is 31, but the minSdkVersion is significantly lower. Increasing the compileSdk of your project is enough to fix the issue.

android {
    compileSdk 31
...
}
