Expected Android API level 21+ but was 30

How is it possible that I get this message? It does not make any sense. I'm using com.squareup.retrofit2:retrofit:2.9.0

Just Add the Dependency implementation 'com.squareup.okhttp3:okhttp:4.9.2'

PS - Check the latest version here before you add the dependency https://mvnrepository.com/artifact/com.squareup.okhttp3/okhttp

Add an explicit dependency on OkHttp 4.9.0. Or whatever is newest at the time you read this.

This bug is embarrassing but it's been fixed for so long that you shouldn’t be encountering it in new code.
