Return of results in extension by means of callback based on

How can I implement the return of results in an extension by means of callback generated in the onActivityResult method?

I have implemented the onActivityResult method with two signatures:

- onActivityResult (int requestCode, int resultCode, Intent data)

- onActivityResult (RhodesActivity activity, int requestCode, int resultCode, Intent data)

but neither of them is ever executed.

I am using Rhomobile 7.3 and I have not found anything about this in the documentation, nor any example that uses this method with this extension format.

I attach the source code of the extension.
