Android Question Creating reusable artifacts with B4A

[Haris Hafeez]

Is there a 'best practices' approach to building some functionality in B4A (such as a custom panel view) and using it outside B4A like in another app written in Java?

For example, if I have my own custom list view implementation in B4A, how to use it in an android app that will be written in Java?

I would say that, once compiled as a library, it becomes converted to java ( a jar and XML file is generated), so it should be possible to use them in a Java written app

Thanks. I'll admit I've never used the 'Compile to Library' feature before so bear with me on this.

When we do compile a project to library, are activities and classes and methods all exported such that their names are the same as in B4A? From what I can recall, the generated code follows a certain pattern (such as lower case, underscore character used for members and methods etc).

You can explore the ProjectName/Objects/src directory to see the generated .java files after a compilation.

It will be difficult to make it work properly. The compiled library makes all kinds of assumptions that will not be valid outside of B4A.

It is much easier to integrate the java code / libraries into your B4A project.

That's what I wanted to figure out.

I understand there's good support for using java libraries and code in B4A but I have a potential use case where my B4A project has large parts that a third party wants to use in their java android app. They're not B4A converts yet(I'm trying
