I want to build a simple Android app, like PushOver app, that has a TCP server and receive text messages which it logs and then send them as push notifications. This part is already done and working fine. But I want to receive messages even if the GUI app is closed. I know that this is possible because PushOver app does it ! I gues, I may need a service… but I don’t know how to make one, because this is my firs Andoroid app. As a development environment I use BeeWare(Toga/Briefcase) and Python on a Kubuntu machine. I activated the USB Debuging on the phone and I run the code directly on Android.
