Android Question Firebase Notification need instant receive the messages.

[tzfpg]

My app need instant receive the notification when server sent out the messages, how can I do that?

My app already add the gps location method to not let system kill my app, but sometimes devices sleep too long, devices can't receive the message.

server side send notification code:

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

I refer the link from firebase website https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages and https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages#androidmessagepriority

How to add the ttl, notification_priority and AndroidMessagePriority to server send notification code?

Thank you.

    Dim Job As HttpJob
    Job.Initialize("fcm", Me)
   Dim m As Map = CreateMap("to": $"/topics/${Topic}"$, "priority": "high")
    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

if I change like this, is it IOS notification also set to high priority?

You can remove the priority setting in line 9. The first one is enough for both platforms.
