Android Question [solved] Local background notification / android 16

[voxel]

Hello,
I'm trying to set up a local notification to be triggered in the background every 30 seconds. It works when the app is in the foreground, but when it's in the background, I get this error.
Thanks for your help.
Is there a link to some sample code? (I couldn't find it on the forum.)

Hint:

MissingForegroundServiceTypeException

Did you set the foreground service type for your service in the manifest?

 

[Erel]

1. targetSdkVersion should be 35 for now.

2. The OS will not let you start a service every 30 seconds. You should instead start the service when the app is in the foreground and keep it running "forever".

3. If you want to start a service while in the background then you should set the foreground type.
For example:

SetServiceAttribute(Service2, android:foregroundServiceType, shortService)

And make sure to add:

Private Sub Service_Timeout(Params As Map)
    Service.StopForeground(NotificationId)
End Sub

Hello,

I add this line in Manifest :

SetServiceAttribute(ServiceNotification, android:foregroundServiceType, shortService)

It works

Thank
