Android Question FirebaseMessaging spawns notification for a second

[Nerdworld]

Hey folks!

Whenever my app is in background and i receive a push message (only data, without notification) my service spawns a single notification.

But for about 2 to 3 seconds there is another notification (obvisouly for the FirebaseMessaging service):

Sub Service_Start(StartingIntent As Intent)
    Firebase.HandleIntent(StartingIntent)
    Sleep(0) ' Regardless of this sleep call
    Service.StopAutomaticForeground ' 2nd notification disappears (2 or 3 seconds too late)
End Sub

It stays until the Service.StopAutomaticForeground is called and disappears.

Can't really figure out what i'm missing here...

Related to:

notification service - firebasemessaging create 2 service

one ofthem run at app was opened. i want to create one service only. please help

Another similiar case here:

Notification service and Service.StopAutomaticForeground : App icon popup

When the service is called from background to foreground, I can see the application Icon popping up into the upper notification area. It remains visible until the service code is completed ( until the Service.StopAutomaticForeground is called ) . This flashing icon can be annoying as it comes...

But removing the Sleep call has no effect.


Best regards

This is the "automatic foreground mode" notification. It needs to be appear until the service can be killed.

I solved it now by calling

Service.AutomaticForegroundMode = Service.AUTOMATIC_FOREGROUND_NEVER

in Service_Create.

It crashes the app after several seconds tho.

Hiding the full error is the best way not to get help ;-)

Sorry! Was still investigating

android.app.RemoteServiceException: Context.startForegroundService() did not then call Service.startForeground(): ServiceRecord{5cd30e1 u0 com.pixelhauer.dmz/.firebasemessaging}

I think i finally solved it:

Starting the foreground service (Service.StartForeground(1, N)) in the MessageArrived sub.

Very expected. You must read: Automatic Foreground Mode

Very expected. You must read: Automatic Foreground Mode

I already fixed the issue (and resolved the problem with the two notifications showing up):

#Region  Service Attributes
    #StartAtBoot: False
#End Region

Sub Process_Globals
    Dim Firebase As FirebaseMessaging
End Sub

Sub Service_Create
    Firebase.Initialize("Push")
    Service.AutomaticForegroundMode = Service.AUTOMATIC_FOREGROUND_NEVER
End Sub

Sub Service_Start(StartingIntent As Intent)
    Firebase.HandleIntent(StartingIntent)
    Sleep(0)
    Service.StopAutomaticForeground
End Sub

Sub Subscribe
    Firebase.SubscribeToTopic("enquiry")
End Sub

Sub Push_MessageArrived(Message As RemoteMessage)
    Dim N As Notification
    N.Initialize
    N.Icon = "icon"
    N.Sound = True
    N.Vibrate = True
    N.SetInfo2(Message.GetData.Get("title"), Message.GetData.Get("text"), Message.GetData.Get("tag"), Main)
    
    Service.StartForeground(1, N)
End Sub

Sub Service_Destroy
End Sub
