Someone can tell me if with the new libraries B4Xlibs or other method it's possible create complete modules (Activity, graphic resources) that can be inserted in more projects.
For example, I need create customer master data, complete with various activities and resources, to be included in many projects.
Yes, you can...
You are talking about a custom view, that in yory case would be a panel/pane to be the width and height of the parent Activity/form.
You can also implement all the logic you need in this custom view regarding automatic procedures and events
