Java Question Compile to library - b4a & b4j

[derez]

I compile to library the same class module in b4a and b4j but the result library compilation in b4a runs only in b4a, not in b4j, and vice versa.
Why ?

 

[giga]

I believe this depends on the library, Could you provide more detail or error messages?

It will not work. You will need to compile the library with B4A and B4J. You can use the new command line builders to automate it.
