I was wondering if it is possible to write one library that works both for B4A and B4J?

For the moment I always create two versions:

B4A:
Referenced libraries:
- B4AShared.jar
- Core.jar
Compile:
- Java 1.7

B4J:
Referenced libraries:
- jCore.jar
Compile:
- Java 1.8

Yes. Any library that doesn't reference an exclusive API can be shared. Use Java 7 to compile it.

And in that case it doesn't matter if I pick Core or jCore or do I include both while developing?

It doesn't matter. The relevant BA methods signatures are exactly the same.
