Hello Erel, or anyone else who has more experience with B4J, i'm playing around with B4J and the capabilities of it, I was trying to make my Graphview Library work with it, but i came a cross an error message, from what i understand is that there's a required class not found and it makes sense since B4J is not android based, but i was wondering if there's a way to make it work, obviously i have no idea where to start, so i'm asking for some help, my graphview library can be found here
http://www.b4x.com/android/forum/threads/graphview-library.34995/#content and below is the error i get when i try to launch the project, any help with this will be greatly appreciated.
