Can you upload the project (with the class source code)?

2 files. bcn is the stripped down class, bcl is the stripped ui that uses it. If compiled to a lib, the timer in the class never ticks. If you include the module in bcl directly, it does.

bcn project should be a ui project.

You cannot use a library created from a non-ui project in a ui project.

That's easy to fix, thank you. Actually, is the opposite true as well? If I build it in a UI can I use it in a non-ui app?

No.

If you need to use the libraries from both a UI and non-Ui applications then you can put the library modules in the shared modules folder and create two projects (UI and non-UI) that use these modules. Now you can create a library for each version.

This is how OkHttpUtils2 is compiled.

But a clarifying question, why do libs like jserver, json, etc work in ui or non-ui aaps?

I don't recommend using jServer in a UI application. It is designed to work in non-ui applications.

There are differences between libraries written in Java and libraries written in B4J. When you write the library with B4J the classes expect a "context" of a specific type.
