Hi,
I've send push notifications with firebase. it's work fine with topics but to single device send fail with "invalid registration token" message.
The token is correctly generated to device and registered in my server.
When I compile the message I pass in the field "to" this but firebase send error.
I've tried to send message at this device token in the firebase console too but I've received same error.
Solved, i don't understand that I must use this code for get token
B4X:
Private Sub GetToken As String
Dim no As NativeObject
Dim token As NativeObject = no.Initialize("FIRInstanceID").RunMethod("instanceID", Null).RunMethod("token", Null)
If token.IsInitialized Then Return token.AsString Else Return ""
End Sub
