Sorry i have tried this wrapper story for last three weeks, It is very week and not success in B4A, for a basic library it will work not a complex, I tries the SLC tool and exposed the Library as explain in the Erel's Posts. Does not work, For your information i made the library and used it in the eclipse it self without any hassle. One my friend used it with a different IDE NetBeans works fine. I think things have to be straight forward since, all the explanations take you all around the world makes it complicated, I think i use the B4A as a RAPID application development toll for android in which i don't expect this to happen. I am sorry if i point it wrong. May be my knowledge
