I receive an error warning in android studio when using a kotlin constructor in a java class.

Timber.plant(new DatadogTree(logger));

"Cannot resolve method 'plant(com.datadog.android.timber.DatadogTree)'"

Compiles fine

I wonder if this is a bug with AS?

Did you get an error or a warning?
What is the baseclass of DatadogTree?

This is not just a Java question. This is clearly around java-kotlin interop

Well its a red squiggly line which indicates error. I'm wondering if this is IDE error or maybe DatadogTree is missing some annotation that expose the constructor to my java class.

Yeah, looks like an IDE issue. Compiling is just fine but has the same issue with i.e. DebugTree. seems AS cannot infer the base class even with this:

final Timber.Tree tree = new Timber.DebugTree();
