(Java/Android) Client-side Socket throwing IOException -

i'm trying connect 2 android devices through sockets, why isn't working? i've tried replacing host address ip address didn't work out.

server side (extends asynctask):

serversocket server; int port; string hostname server = new serversocket(0); port = server.getlocalport(); //is sent client via or code (enumeration<networkinterface> en = networkinterface.getnetworkinterfaces(); en.hasmoreelements();) { networkinterface intf = en.nextelement(); (enumeration<inetaddress> enumipaddr = intf.getinetaddresses(); enumipaddr.hasmoreelements();) { inetaddress inetaddress = enumipaddr.nextelement(); if (!inetaddress.isloopbackaddress()) { hostname = inetaddress.gethostname(); //is sent client via or code } } } socket client = server.accept();

client side (extends asynctask):

socketaddress socketaddress = new inetsocketaddress(serverhostname, serverport); client = new socket(); client.bind(null); client.connect(socketaddress, socket_timeout); //exception happens in method connected = true;

here stack trace:

i've solved problem. turns out should have used code on client before socket creation, , had alter thing work ip addressed instead of host names.

inetaddress addr = inetaddress.getbyname(serverip); socketaddress socketaddress = new inetsocketaddress(addr, serverport); //here follows old client code socketaddress socketaddress = new inetsocketaddress(serverhostname, serverport); client = new socket(); client.bind(null); client.connect(socketaddress, socket_timeout); //exception happens in method connected = true;
