b4a library

I want to use a third party API in my project. but there is only an jar file I notice that b4a library includes one jar file and one xml file Is there a tool that can create the xml file or how can I convert it to b4a library ? Thanks.

Hello all, what's the best and updated tutorial to create a B4A LIbrary from an Android library (.jar and .aar)? I found this : https://www.b4x.com/android/forum/threads/create-a-wrapper-library-with-android-studio.82831/#content , but it's from 2.017... does still work?
