Abstract
Another one in my 'I don't like doing repetitive stuff' repertoire. The rationale for this one is to avoid having to code the 'boring stuff', i.e. CRUD for data tables (usually slightly or completely different than others from other programs) in a new program, again and again.
The idea...
Yes. It is within the reach of b4x, and now with b4j whether as a native code or by java code. What matters is that it runs within the realm of b4x.
However, it was not that easy to implement.
Here is the result.

Hi all, I would like to read from any success stories using ABMaterial framework, has anyone actually either for personal business purposes or for a client built a successful web app that is still currently being used by more than 1000 users on a daily basis.

AI image and video generation is getting more popular. Most of the ai image generation sites are paid, some with free plans.
I tried my luck with one of them. First I signed-up them I got my API key, finally I summoned the powers of B4X to generate an ai image.

Hello Friends!
I'm starting a new project on B4J, that will run on Windows and Linux desktops. The app needs to use a 3rd party external library (.DLL and .SO).
What is the best way for writing this app? Create a wrapper of DLL and .SO and use it depending on target OS?
There is any tutorial...
This application showcases the use of B4X views and the multi platform programming with the #If B4A and #If B4J directives.
This is how it looks like (first on my laptop then on my smartphone):
A short description is available in the attachment: color_selector.pdf
You can find the source codes...
Is there such a view in B4J that allows the user to manually re-order the cells in the list? I am looking for something rather like xCustomListView that responds to drag events?
I have a mobile app that is used for configuring our company's wireless sensors over a BLE connection.
The source code has been through many revisions since the early days of B4A and needs updating to B4X as a step towards an iOS release for the Apple Store.
The app contains a large number of...
