Java Question Share a B4A library with java programs

[rbirago]

I've seen a lot of questions about java libs wrap to B4A...but I have the opposite question: I've created a lot of custom functions in a B4A lib and now I'd like to use these functions in java programs. Is it possible? If so, what about types compatibility (Lists, Maps, etc.)?

thank you

The java code b4a creates is designed to work in a B4X Process.
Most probably you are not able to use it in Java.

I understand...so, if I want to share these functions perhaps I have to rewrite them in java and then wrap them to B4A?
...and what about the compatibilities of types between java and B4A? where can I find a table of something similar to match the various types?

 

[DonManfred]

I don´t know there is one. You need to find out by yourself.

.and what about the compatibilities of types between java and B4A?

Going from Java to B4A should be simple in most cases. You can see all the hundreds of libraries available.
The other direction is more complicated and not recommended.

So if I want to create a library shared between Java and B4A I have to create it in Java and then build a wrapper to use it also in B4A? is this the way?

 

[DonManfred]

yes

ok, thank you.
