has someone an example on how to use the alertdialog builder with setMultiChoiceItems in an own library?
-How to implement the required an OnMultiChoiceClickListener?
-How to return the selected booleans? Expect a list, but how to fill the list and return to B4A?
that is of course an option BUT I would like to learn more on how to develop B4A libraries, esp. handling events, retrieving results etc. Did look at your tutorial, but need to learn more.
