Android Question Service.StartForeground(1, Notif1) under Android 13

[peacemaker]

HI, All

How to use a foreground service under Android13, if notifications are not required ?
Locally working app with timers and screen.

Sub Service_Create
Notif1.Initialize2(Notif1.IMPORTANCE_LOW)
Service.StartForeground(1, Notif1)

Notif1 is required for StartForeground, but

java.lang.ClassCastException: anywheresoftware.b4a.objects.NotificationWrapper$NotificationData cannot be cast to android.app.Notification

I have the same problem, did you find a solution?

no yet

I've updated this project: https://www.b4x.com/android/forum/threads/background-location-tracking.99873/#content
Please check it.

Thanks, Erel. So, for notifications the .SetInfo method is the must for usage, and requesting PERMISSION_POST_NOTIFICATIONS also.

 

[peacemaker]

But if it needs a foreground service, but without notifications - it is not possible, as i can understand, as at least one notification must be made for service creation.

Yes. It was always needed.

But if it needs a foreground service, but without notifications - it is not possible,

This was always the case.

Only the post notification permission is new.
