Android Question Firebase Messaging - FCM console works, not the B4J-SendMessage tool

[mmieher]

Sending notifications from the FCM console is now working after a friend straightened me out earlier.

Having trouble creating a notification all by myself. Everything looks groovy in the B4J log, but the device never gets the message.

Sub AppStart (Args() As String)
    SendMessage("general", "mis title", "body slam")
    StartMessageLoop
End Sub

Private Sub SendMessage(Topic As String, Title As String, Body As String)
    Log("Topic:  " & Topic)
    Log("Title:  " & Title)
    Log("Body:   " & Body)
    
    Dim Job As HttpJob
    Job.Initialize("fcm", Me)
    Dim m As Map = CreateMap("to": $"/topics/${Topic}"$)
    Dim data As Map = CreateMap("title": Title, "body": Body)
    
    If Topic.StartsWith("ios_") Then
        Dim iosalert As Map =  CreateMap("title": Title, "body": Body, "sound": "default")
        m.Put("notification", iosalert)
        m.Put("priority", 10)
    End If
    
    '    neither seems to matter
    m.Put("android", CreateMap("priority": "high"))        '    Erel
    ''m.Put("android", CreateMap("priority": 10))        '    Marc - what am i thinking?
    
    m.Put("data", data)
    Dim jg As JSONGenerator
    jg.Initialize(m)
    
    Log("POST:  " & jg.ToString)
    Job.PostString("https://fcm.googleapis.com/fcm/send", jg.ToString)
    Job.GetRequest.SetContentType("application/json;charset=UTF-8")
    
    ''Log("using API_KEY" & CRLF & API_KEY)
    Job.GetRequest.SetHeader("Authorization", "key=" & API_KEY)
    
End Sub


Sub JobDone(job As HttpJob)
   Log("JobDone:  " & job.Success)
   If job.Success Then
     Log(job.GetString)
   End If
   job.Release
   ExitApplication '!
End Sub

Log:

This is my sub to send to a topic.

 Private Sub SendMessageToTopic(Top As String, MyData As String)
 
   Dim Job As HttpJob
   Job.Initialize("SendMessage", Me)
  
    Dim m As Map = CreateMap("to": $"/topics/${Top}"$)
      
    Dim data As Map = CreateMap("md": MyData)
    Dim pri As Map=CreateMap("priority":"high")
    m.Put("data", data)
    m.Put("priority", "high")
    m.Put("android", pri)
    
 
    Dim jg As JSONGenerator
    jg.Initialize(m)
    Job.Tag=jg
    'Log(jg.ToString)
    Log(jg.ToPrettyString(2))
    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)
  
    Wait For JobDone(Job As HttpJob)
    If Job.Success Then
        Dim RES As String = Job.GetString
        Log(RES)
        Dim parser As JSONParser
        parser.Initialize(RES)
    End If
  
  
  
  End Sub

All that I can say is that once everything is configured properly, it will work.

Don't miss the manifest editor code.

What is the output of:

Public Sub SubscribeToTopics
    fm.SubscribeToTopic("general")
    Log("token: " & fm.Token)
    Sleep(1000)
    Log("token: " & fm.Token)
End Sub

?

Thanks, Erel. I get a big fm.token thing that I do not know what to do with.

I am confused by all of this. I get notifications when using Firebase console even when my App is not "running" and I temporarily removed the n.notify(1) from fm_MessageArrived in my B4A app?

Firebase Console uses a different type of notification messages.

Make sure that targetSdkVersion is set to 30 and not 31.

It is set to 30. I probably need to download updates for the SDK, but I see conflicting messages about whether or not I should ever use the B4A IDE to do so. My personal experience is that using the IDE to update the SDK messes other things up to the point I have to restore c:\Android from a backup.

No need to update anything assuming that you downloaded the prepackaged SDK in the last year. If not, delete it and download again.
