Android Question Does the B4x package have tools to automatically translate B4j code to B4a code?

[oleg_]

If I understand correctly, in the B4j language you can create programs for Windows, and in the B4a language you can create programs for Android. Moreover, these languages are very similar to each other.
I'm wondering if there is any tool in the B4x package to automatically translate B4j code into B4a code or will I have to do it manually?

I'm an amateur, not a professional. I write all programs only for myself. Is the following tactic possible for me?
I create all the programs in B4j so that they run on a desktop Windows computer, and I translate some of these programs (automatically?) into B4a code and use these programs on the Android tablet? Or is it easier to create programs for an Android tablet right away in the B4a language?

You just have to create a b4x project. Make sure you use b4xviews or b4x custom views. Write one code and copy your layout to different platforms.

I suggest you to directly begin with a B4XPages project.
You may have a look at the B4X Getting started booklet.
The first project 'MyFirstProgram' is a B4XPages project.
The advantage is that almost all code is common to all three platforms.

jahswant, thanks for the answer.
I can’t say that I understood everything from this, since I’m just starting to get acquainted with all these products. But I've still understood the main thing: there is a way to translate B4J to B4a automatically or almost automatically, and it is very good.

klaus, thank you very much for the advice!
At the beginning of the journey, I really want to choose the right direction to move and you help me just with this.

Welcome to the B4X community @oleg_

Once you have studied the B4X getting started booklet that has been expertly written by @klaus, I would recommend that you quickly looking at this cross platform example(s) (a simple Simon Says game) in the links below. This cross platform example is basically one set of code that is running the same game example on Android, iOS, Windows and MacOS operating systems. This is a relatively simple one code fits all example for beginners. As long as you use B4XPages with XUI, you should be able to accomplish most (if not all) of the cross platform projects you would probably like to create.

The two links below are for B4A (Android) and also B4J (Desktops), they download the exact same zip file and share the same simple to follow source code. You can open the project twice (one in B4A and the other in B4J) and for example when you change the source code in B4A, you will see the source code changes happen in B4J just a few seconds later.

Hello to you all, I decided to recreate this simple but effective game example, the game is based on the B4XPages library. The game is designed for hand, eye and memory coordination, so I called it 'Erel Says' ;) I've tried to make the code as simple as possible to follow for new to B4X...

Peter Simpson, thank you very much for the explanation.

Peter, maybe you should remove the n't from the sentence here? It seems confusing.

Dam typo autocorrection can be a pain at times. Cheers for the feedback as I typed post #4 out on my phone whilst watching the movie LIFT.
