android - IOException: socket failed: ACCESS (Permission denied) -
i'm trying make simple android client-server app send string server.
client:
public class mainactivity extends actionbaractivity { edittext et; button btn; private socket client; private printwriter printwriter; private string s; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); et = (edittext) findviewbyid(r.id.et); btn = (button) findviewbyid(r.id.btn); btn.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { s = et.gettext().tostring(); et.settext(""); try { client = new socket("192.168.1.14", 4444); printwriter = new printwriter(client.getoutputstream(), true); printwriter.write(s); printwriter.flush(); printwriter.close(); client.close(); } catch (unknownhostexception ex) { toast.maketext(getapplicationcontext(), "unknownhostexception: " + ex.getmessage(), toast.length_long).show(); } catch (ioexception ex) { toast.maketext(getapplicationcontext(), "ioexception: " + ex.getmessage(), toast.length_long).show(); } } }); } } server:
public class main { private static serversocket serversocket; private static socket socket; private static inputstreamreader inreader; private static bufferedreader bufferedreader; private static string s; public static void main(string[] args) { char port = 4444; try { serversocket = new serversocket(port); } catch (ioexception e) { system.out.println("could not listen on port " + port); } system.out.println("server started. listening on port" + port); while (true) { try { socket = serversocket.accept(); inreader = new inputstreamreader(socket.getinputstream()); bufferedreader = new bufferedreader(inreader); s = bufferedreader.readline(); system.out.println(s); inreader.close(); socket.close(); } catch (ioexception e) { system.out.println("problen in message reading!"); } } } } androidmanifest.xml:

i'm running server on drjava, problem?
i'm getting error: "ioexception: socket failed: access (permission denied)".
write down snippet below setcontentview()
if (android.os.build.version.sdk_int > 9) { strictmode.threadpolicy policy = new strictmode.threadpolicy.builder().permitall().build(); strictmode.setthreadpolicy(policy); } or
class mytask extends asynctask<void, void, void> { @override protected void onpreexecute() { super.onpreexecute(); } @override protected void doinbackground(void... params) { // request } @override protected void onpostexecute(void result) { super.onpostexecute(result); } }
