facing this
tcp_client_endpoint::connect: Error binding socket: Cannot assign requested address local: 0.0.0.0:0 remote:192.168.1.138:30509

Hi i can understand your probelm the issue is your vsomeip library has to read the vsomeip.json configuration file, but because in android , vendor partion is not accessible , either chnage the path to /data/local/tmp in vsomeip library code, give static ip to your android device ,give route as well , give a default gateway which is same for both linux and android. like below.

chmod 777 /data/local/tmp/
ip addr add 172.17.0.2/16  dev eth0
ip route add 224.224.224.245 via 172.17.0.254 dev eth0  

,by doing this i was able to recieve message from linux in android however the server was not sending back the message. and there was no error. , when i checked the tcpdump i can see packet being recieved , but there is not outgoing packet.
