Research direction

Start by reproducing the Android foreground-service case with PySide6 and QCoreApplication, then inspect the logcat crash dump described in the issue. Determine whether the service can support QCoreApplication and document the required integration or limitation; the issue names no repository files or tests.

Written by the indexing model from the issue text.

Description

I created a graphical app using PySide6 and QML and deploys it to Android which works fine, I also created foreground services in python-only code and they also work fine, but when I create a foreground service which uses QCoreApplication for some QtCore stuffs like signal and slot and event-loop management, the moment I create the QCoreApplication, the service crashes with a crash dump in log-cat

Can anyone guide me why this is happening and how can i use the Pyside6 and QCoreApplication inside a foreground service?

Thanks
