Hi, as I said, I love b4A , but I see that b4a is missing of modern function, I made the example of video streaming, not as viewer but as sever, is not possible to make a video call peer to peer application without using a external service like ooVoo VideoConferencing, the nfc library doesn't support the not so new feature 'hce, and always for example the webrtc api are not implemented, and webrtc are been introduced whit lollipop, now are about to marshmallow. I love b4a and never I will change it, but it seems that the core library are not updated so fast as Android do.
