Hi
I'm so lost, i have for several weeks now tried to make wrapper for a connection to a service that connects to a creditcard terminal.
So far it manage to get a connection, but i wan't to raise a event when that happens in the B4A application.
I have no idea what i'm doing wrong. I'm pretty shitty at programming i Java as you can see.
So I just throw out part of the code here hoping, and to see if anyone can point me in the right direction.
