AttributeError: 'org.kivy.android.PythonService' object has no attribute 'getComponentName'

Description

I have a simple Kivy application that has a foreground service. When I try to send a notification via plyer in this service, I get an error AttributeError: 'org.kivy.android.PythonService' object has no attribute 'getComponentName'
