B4J Question Converting B4A to B4J ?

[regwbr]

Is there a listing somewhere of what the differences are? I know using javaFX and some of the differences with it. What about coding difference?

With my B4A code I do a StartActivity() to go to my next code module. What do I replace that with in B4J?

My next question is Android stacks screens on top of each other and B4A needs to back out of the stack for a clean exist. Does Java and B4J respond the same way?

I also downloaded the HowToTip tool and could not find any hits for my questions.

Thanks. I have already been through that and a number of other tutorials. I haven't found any yet that talk about how to change code from a B4A activity to a a B4J "something".

"Something" should be a static code module. B4J (and B4i) are more flexible. A static code module is equivalent to both service and activity.

B4J Form object is not really different than Button or String. You can have any number of forms in a single module. It is up to you.
