i have implemented code below. server receives image client , matlab detects object , save new image face.jpg trying send points client code stucks in ////////// part of client code:
///////////////////////////////////////////////////////////////////////////////////////////////////////////////// thread.sleep(15000); log.d("mytag","test message11"); try { points = infromserver.readline(); }catch(exception io){ log.d("mytag","fails read server"); } log.d("mytag",points); sock.close(); //////////////////////////////////////////////////////////////////////////////////////////////////////////////////// the whole android client code here.any idea guys? please help.
