I saw that you put
your question more than a year ago.
As there are no other answers in this new thread too, I think that:
a) there is no one interest in this feature (or they didn't see the posts)
b) if is there no one, maybe you can hire someone to made a wrapper of the API to you
c) or you can try check how Java works with B4X and try to use the Java code or created your own wrapper, posting the doubts and the progress of the work here to get help.
