Android Question I need Tutorial for Create a Library of Custom Control

Hello to all,
it would be useful to have a tutorial to create a wrapper of a standard or custom control to be transformed into library for B4A.

For example, a custom edit control to be extended in Java and transform the bookstore to B4A.

I saw that there is a tutorial to create a generic library, but do not know the steps to make the control wrapper.

What do you recommend to use: Eclipse, Android Studio or Library Compiler?

Thank you
