[Erel]

into a mini pc server run under android 9 Pie.

If you can install Linux on the pc then do it and switch to B4J jServer. It is 1000 times more powerful.

The error means that the server port is already used. Change it from 5555 (ServiceServer) to something else.

Hi Erel,
Tks and it's working now after changing the port.
will follow your suggestion and assistance...
