Android Question SOLVED Oreo and B4A 8 notify icon is wrong

[coslad]

Until b4a 7.80 everything was right , but with B4A 8 and Oreo appen a strange thing :

If the service is started automaticaly at boot (start at boot option) the service notify icon is wrong , it appers the icon of application :



instead if a stop the app and restart it or if i start the app from the b4a bridge , the service is started from main activity :

If comunicazione.avviato=False Then StartService(comunicazione)

appears the right icon :



any idea ?

If sdk >= 22 than the icon alpha levels are used as a mask.

You are seeing the default automatic notification: https://www.b4x.com/android/forum/threads/automatic-foreground-mode.90546/#content
You can change the notification object or stop it immediately or set the mode to NEVER.

Hi

i solved with this :

I create a new service , this new service start at boot and call StartService(comunicazione) , in the 'comunicazione' service the #StartAtBoot is set to false.

In this way the icon is right and i can change that icon if for example the connection is lost.

But why if i set false to vibrate , it Always vibrate ?

client.Subscribe("all/#", 1)
            client.Publish2("all/connect", serializator.ConvertObjectToBytes(currentName), 1, False)
            Notification1.Initialize2(Notification1.IMPORTANCE_HIGH)
            Notification1.Icon = "casa_conn"
            Notification1.Vibrate=False
            Notification1.Sound=False
            Notification1.SetInfo("Casa","Connesso" & (DateTime.Time(DateTime.Now)) ,Main)
            Notification1.Notify(1)

On Android 8+ the notification behavior depends on the importance level.
