Where to put "custom conversions" with @BindingConversion in Android Data Binding and why?

Question

The official documentation on custom conversions in Android Data Binding is pretty scant. It says to create a static converter with the method signature to match the conversion, and annotate it with @BindingConversion, but it doesn't say where it will look for those methods. Does it just scan every static method in the whole app for BindingConversion annotations? Should I create a specific class for these conversions? Should it be in a specific package? Obviously it should be public. Please elaborate.

Answer 1

Yes, it can be any class in any package. It uses the java annotation processor, so it only picks up the annotated methods.
