Android Question MQTT MessageArrived IO exception

[engvidal]

Hi

Using this sub:

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:

Erel posted the solution here https://www.b4x.com/android/forum/threads/convert-array-of-bytes-to-string.70363/#post-446792
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.
