Android Question Send notification to single device with Firebase

[FatihCubukcu]

I am trying to send notification to single device using firebase. I write the information I get with the Log("Token:" & GetToken) code to the Id section, but still all devices are notified. Where am I doing wrong?

Private Sub SendMessage2(id As String, Title As String, Body As String)
    Dim Job As HttpJob
    Job.Initialize("fcm", Me)
    Dim m As Map = CreateMap("to": $"${id}"$)
    Dim data As Map = CreateMap("title": Title, "body": Body)
    m.Put("data", data)
    Dim jg As JSONGenerator
    jg.Initialize(m)
    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)
End Sub

For Example

SendMessage2("eleYgmQySGCe9yJnZBcWpR:APA91bFtjyTHoVLTZo_w88JLrQhtbu5vsckhy..................", "title", "body")

See the example B4J code from the Firebase Messaging tutorial. This sends the message to the TOPIC xy.

Private Sub SendMessage(Topic As String, Title As String, Body As String)
    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
    m.Put("data", data)
    Dim jg As JSONGenerator
    jg.Initialize(m)
    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)
End Sub

Your code sends to a specific token but i fear you are registering this token? with all devices?

please post your SubscribeToTopics sub.
I fear you are doing something weird?

hello, thank you for your quick reply.
I have read the Firebase Messaging tutorial but I don't quite understand how can I send the token I bought to a single device? Do you have an example code?

Do you have an example code?

as i wrote you are using the correct code i think.

The problem must be sonething other.

Just replace data with notification and add empty data value:

Private Sub SendMessage2(id As String, Title As String, Body As String)
    Dim Job As HttpJob
    Job.Initialize("fcm", Me)
    Dim m As Map = CreateMap("to": $"${id}"$)
    Dim notification As Map = CreateMap("title": Title, "body": Body)
    m.Put("notification", notification)
    m.Put("data", "")
    Dim jg As JSONGenerator
    jg.Initialize(m)
    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)
End Sub
