I developed a small application that should query data via Remote Procedure Call (using Pyro4) and display it on the mobile phone - only when the user populates a field and clicks a button.
I also developed the service, which I run on my notebook (Windows).
Testing this application directly on the notebook works fine. On the phone, via Kivy Launcher, the screen does not even open - it closes the Kivy Launcher. I put in the code an exception handling for it to insert the log into a json file in the same application folder, but that does not even happen.
The android.txt file is there in the mobile app folder, and other applications that I have created open normally in the Kivy Launcher.
What can it be?
