In 2018 I wrote a label printing program, the code still runs smoothly, no problem; though, I did not developed any app running B4A since then. I am asked to make some small changes on the app. To run the app, I downloaded the latest version of B4A, and did the necessary configurations ( Javac.exe-library file path-android jar.)
Yet, the program does not run at all, there is no warning or error code. It does not work, when I start as a new project either.
When I run it in debug mode, this screen appears.
I use B4A- bridge for debug.
What changed in the last two years? What did I miss guys?? I am waiting for your comments and your help. Thank you
