B4J Question Newbie Question: Creating a cross platform app

[Nathan Wright]

Hi, I am new to B4X and am trying to build a desktop (Windows, Mac and Android), Apple (iPhone and iPad), Android (Phone and Tablet).

I understand that I will need to create the UI in B4I, B4J and B4A but I will have lots of logic that needs to be shared between the different B4? products but this is where I am confused. The UI will be talking to a REST API that I have created and the communication SUBs will be the same and this is what I want to share between all the apps.

Can anyone recommend a tutorial or forum posts or documentation that would help me understand how this should be done.

Thanks

Nathan

Check out Erel's videos:

The videos named "XUI - Cross platform UI" and "XUI Cross Platform Example" show a use case where you share the same code within the B4X platform.
Those can be a good start.

Implement everything that you can in classes. Share the classes between the projects: https://www.b4x.com/android/forum/threads/86587/#content

The games examples pack is a good example of sharing code between the three platforms: https://www.b4x.com/android/forum/threads/xui2d-example-pack.96454/ (95%+ of the code is shared).
