Android Question filebase cloud message limit

[peacemaker]

Hi, All

Who already used Google Firebase cloud messaging ?
If the each message is limited by some digit around 4K bytes - how to control it ? If message prepared is longer ? Will it be some sending error or what ?

Did you tried to send 16kb?
It should raise an error cause it is more than the allowed size

Not tried, and asking. So, we must check the JSON generated text to be sent before sending...
How to be sure if data is variable....
OK, thanks, DonManfred

Yes. Check the length of the jsonstring before sending....

And the answer is:

Sub AppStart (Args() As String)
   Dim sb As StringBuilder
   sb.Initialize
   For i = 1 To 16000
     sb.Append("a")
   Next
   SendMessage("general", "title", sb.ToString)
   StartMessageLoop
End Sub

Output:
{"error":"MessageTooBig"}
