Were working with industrial Android HMI Panels.
In our application we need to set the ethernet settings.
I got a Android studio project from the manufacturer.
But i dont know how to use it in B4A. I tried inline java but getting lots of error due my missing java knowledge.
Can someone help me to convert this?
