Android Question Network is unreachable

[M.LAZ]

Hi
i got this error when trying send data from b4a app to my pc server using b4j
using this example
(ErrnoException) android.system.ErrnoException: isConnected failed: ENETUNREACH (Network is unreachable)
i allow all incoming communication with port.
is there something else to configure ?

Make sure that the ip and port are correct. There could also be several firewalls running.

It is easier to start with the Android device as a server. Start with this example: [B4X] [B4XPages] Network + AsyncStreams + B4XSerializator

thanks Erel . it's working now it's an ip problem
yes i'm starting using this example [B4X] [B4XPages] Network + AsyncStreams + B4XSerializator
but Now i want to make a concurrent connections to Server , this Example use just one connection how to modify it?

Good, simple and very powerful solution: use jServer to build a real server.

Complex and much less powerful solution - examples:
[B4X] FTP Server implemented with Socket and AsyncStreams
MJPEG / CCTV Server
