///client code....

            try {                 socket s = new socket(txtip.gettext().tostring(),integer.parseint(txtport.tostring()));                 objectinputstream oos = new objectinputstream(s.getinputstream());                      byte[] buffer = (byte[]) oos.readobject();                     fileoutputstream fos = new fileoutputstream("/storage/123.jpeg");                     fos.write(buffer);              } catch (ioexception e) {                 toast.maketext(mainactivity.this,""+e,toast.length_long).show();             } catch (classnotfoundexception e) {                  toast.maketext(mainactivity.this,""+e,toast.length_long).show();             }          }     }); }

i wrote small awful library did this. can use java sockets.

have 1 device run serversocket in app, socket can listen connections (like server). need check on port serversocket listening (google it). need ip address of device, there few way: can wifimanager (google it).

other device use socket class connect it. can send data in multiple forms: plain strings or if use same app can serialize/deserialize objects.

read bit sockets, after serversocket connection other device, can exchange messages (just keep listening in loop on other thread).
