Android Question MQTT MessageArrived IO exception

engvidal · Aug 26, 2016

Hi

Using this sub:

B4X:

Private Sub mqtt_MessageArrived (Topic As String, Payload() As Byte)
  Dim obj As Object = serializator.ConvertBytesToObject(Payload)
  Dim s As String = obj

  Label2.Text = s
End Sub

Just at start up, and after that, if I choose 'continue', on each message arriving, I get:

java.io.IOException:

Why you still use the code you was using before???

If you still haven't resolved this issue then please post the code that sends the message. It is impossible to say how the payload should be treated without seeing it.
