Android Question Firebase notifications (key/value)

[aidymp]

Can we use the key / value part of the firebase notifications? if so how would you implement this?

I believe that if you put something like START and PAGE2 and some code to receive the key/value anyone opening the notification the app would open on page2 (that's just an example) can anyone shed any light on this?

Thanks

Aidy

To send a message to a single device (id = token):

Private Sub SendMessage(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

It's very easy. Just follow the steps in Erel's example.

Just debug what the device receives Just send a message and see...

Sub fm_MessageArrived (Message As RemoteMessage)
   Log("Message arrived")
   Log($"Message data: ${Message.GetData}"$)
  
   Dim Data As String = Message.GetData.Get("message")  
   
End Sub

Your are free which key/value pairs you use:

Dim Job As HttpJob
   Job.Initialize("Loc", Me)
   Dim m As Map = CreateMap("to": $"${devtoken}"$)
   Dim data As Map = CreateMap("nick": Nick, "loc": loc)
   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)

Here I use "nick" and "loc". As I've written: Just try... (send & debug)
