Measuring Network Throughput Java/Android -
i'm doing app android, , want measure network throughput using http. far have done code makes http www.google.pt page. measure time between before , after request.
the problem: i'm measuring time of entire data exchange between server , app, overhead of tcp protocol. need time takes app receive webpage (useful data).
i have used wireshark see happens during request. useful data pdu's see. that's want.
public static string get(string url){ inputstream inputstream = null; string result = ""; try { // create httpclient httpclient httpclient = new defaulthttpclient(); // time functions before calendar calendarbefore = calendar.getinstance();// instance class calendar int millisecondsbefore = calendarbefore.get(calendar.millisecond); // make request given url httpresponse httpresponse = httpclient.execute(new httpget(url)); // time functions after calendar calendarafter = calendar.getinstance();// instance class calendar int millisecondsafter = calendarafter.get(calendar.millisecond); // time difference calculation int timediff = millisecondsafter - millisecondsbefore; string timedifference = new string(); // time difference (after-before) //verify signal of timedifference value if(timediff < 0){ timediff = timediff * (-1); // reverse signal in operation timedifference=integer.tostring(timediff); } else{ timedifference=integer.tostring(timediff); } // receive response inputstream inputstream = httpresponse.getentity().getcontent(); // convert input stream string if(inputstream != null) result = convertinputstreamtostring(inputstream, timediff); else result = "did not work!"; } catch (exception e) { log.d("inputstream", e.getlocalizedmessage()); } return result; } so, i'm measuring lot of things don't need. need measure time takes receive pdu's.
if guys know can me, me lot. if have other suggestion, love hear.
thank you!
may can help:
public static string get(string url){ inputstream inputstream = null; string result = ""; try { // create httpclient httpclient httpclient = new defaulthttpclient(); //get bytes of data consumed long oldcount = android.net.trafficstats.getmobilerxbytes(); // make request given url httpresponse httpresponse = httpclient.execute(new httpget(url)); //get bytes of data consumed long newcount = android.net.trafficstats.getmobilerxbytes(); //gettotaldata consumed log.i("totaldataconsumption",(newcount-oldcount)+" bytes"); // receive response inputstream inputstream = httpresponse.getentity().getcontent(); // convert input stream string if(inputstream != null) result = convertinputstreamtostring(inputstream, timediff); else result = "did not work!"; } catch (exception e) { log.d("inputstream", e.getlocalizedmessage()); } return result; }
