You need to set both compileSdkVersion and targetSdkVersion to 31 in your build.gradle(app) file.

android {
    compileSdkVersion 31 // <-- This
    defaultConfig {
        applicationId "com.example.app"
        targetSdkVersion 31 // <-- and this too
        // ...
    }
}

The build.gradle (app) is in the /app/build.gradle of the project.
