Android Question FirebaseNotifications data null

[gerredtor]

hello i send from firebase a notification, and the data return null:

Message data: {}

my code(from the tut):

Sub fm_MessageArrived (Message As RemoteMessage)
   Log("Message arrived")
   Log($"Message data: ${Message.GetData}"$)
   Log($"Message: ${Message}"$)
   Dim n As Notification
   n.Initialize
   n.Icon = "icon"
   n.SetInfo(Message.GetData.Get("title"), Message.GetData.Get("body"), Main)
   n.Notify(1)
End Sub

yes i have tested this, but the standart settings ? i will use this

 

[gerredtor]

look my picture.

i will use this, it only works for me when i fill key and value.. but this is a very inefficient way for supporters and others..

and my code is from the tut for testing:

Starter:

Sub Service_Create
    CallSubDelayed(FirebaseMessaging, "SubscribeToTopics")
End Sub

FirebaseMessaging:

Sub Process_Globals
   Private fm As FirebaseMessaging
End Sub

Sub Service_Create
   fm.Initialize("fm")
End Sub

Public Sub SubscribeToTopics
   fm.SubscribeToTopic("general") 'you can subscribe to more topics
End Sub

Sub Service_Start (StartingIntent As Intent)
   If fm.HandleIntent(StartingIntent) Then Return
End Sub

Sub fm_MessageArrived (Message As RemoteMessage)
   Log("Message arrived")
   Log($"Message data: ${Message.GetData}"$)
  
   If Message.GetData == Null Or Message.GetData.Get("title") == Null Then
       Return
   End If
  
   Dim n As Notification
   n.Initialize
   n.Icon = "icon"
   n.SetInfo(Message.GetData.Get("title"), Message.GetData.Get("body"), Main)
   n.Notify(1)
End Sub

Sub Service_Destroy

End Sub

You should send the message using the REST API.

I've played with the tutorial software a bit and it works as long as the program is active as a service. The moment I activate the program and leave the main program active the first message succeeds but the following messages all return data "null". All help is appreciated.

See here (my explanations at the end): https://www.b4x.com/android/forum/t...rebase-opener-notification.72642/#post-462424

As you see the "notification" is in real a message which has two parts: the notification AND the data (or only one of them). Google handles the notification automatically for you when the app is in the background Only when the user clicks on it, the app starts again (like WhatsApp).

'{
'    "to" : "APA91bHun4MxP5egoKMwt2KZFBaFUH-1RYqx...",
'    "notification" : {
'      "body" : "great match!",
'      "title" : "Portugal vs. Denmark",
'      "icon" : "myicon"
'    },
'    "data" : {
'      "Nick" : "Mario",
'      "Room" : "PortugalVSDenmark"
'    }
'  }
  
  
   Dim m As Map = CreateMap("to": $"${Devtoken}"$)
   Dim noti As Map = CreateMap("body":"great match!","title":"Portugal vs. Denmark","icon": "myicon")
   Dim data As Map = CreateMap("Nick":"Mario","Room":"PortugalVSDenmark")
   m.Put("notification", noti)
   m.Put("data", data)
   Dim jg As JSONGenerator
   jg.Initialize(m)
   Job.Tag=jg
   Job.PostString("https://fcm.googleapis.com/fcm/send", jg.ToString)
   Job.GetRequest.SetContentType("application/json;charset=UTF-8")
   Job.GetRequest.SetHeader("Authorization", "key=" & API_KEY)

I'm having the same problem, except I am trying to send a notification from Google Firebase console. I fill in the Message Text and also the Title but the app returns null.

Don't use firebase console, use the b4j code!

ME TOO; The problem is in receiving msg! If activity hidden/in background i receive notification title/body, but when activity in foreground i got null for both title & body!!!
Any suggestions ...
