Android display Timeout Message in Web Service when connection or read timeout while internet connected -

hi need display message "data not received" on connection or read timeout.

i implement using java.net.sockettimeoutexception can't message if there no data received while internet connected.

i through internet connected or not.

but want when internet connected.

internet connectivity test code

public static boolean isnetworkconnected(activity activity) {     connectivitymanager connectivity = (connectivitymanager) activity.getsystemservice(context.connectivity_service);     if (connectivity != null) {         networkinfo[] info = connectivity.getallnetworkinfo();         if (info != null)             (int = 0; < info.length; i++)                 if (info[i].getstate() == networkinfo.state.connected) {                     return true;                 }      }     return false; } 

code

@override protected string doinbackground(string... params) {     // todo auto-generated method stub     string result = "";     try {         url url = new url(params[0]);         httpconnection = (httpurlconnection) url.openconnection();         httpconnection.setrequestproperty("accept", "application/json");         httpconnection.setreadtimeout(10000);         httpconnection.setconnecttimeout(15000);         httpconnection.setrequestmethod("post");         httpconnection.setdoinput(true);         httpconnection.setdooutput(true);          outputstream os = httpconnection.getoutputstream();         bufferedwriter writer = new bufferedwriter(new outputstreamwriter(os, "utf-8"));         writer.write(string.valueof(values));         writer.flush();         writer.close();         os.close();          int responsecode = httpconnection.getresponsecode();         if (responsecode == httpurlconnection.http_ok) {             inputstream istream = httpconnection.getinputstream();             inputstreamreader isreader = new inputstreamreader(istream);             bufferedreader br = new bufferedreader(isreader);             string line;             while ((line = br.readline()) != null) {                 result += line;             }         }     } catch (java.net.sockettimeoutexception e) {         toast.maketext(context, "network error : no data received.", toast.length_short).show();     } catch (exception e) {         // todo: handle exception         e.printstacktrace();         log.e("error : ", e.tostring());     }     return result; } 

for displaying toast:

catch (java.net.sockettimeoutexception e) {      runonuithread(new runnable() {                 @override                 public void run() {                     toast.maketext(context, "network error : no data received.", toast.length_short).show();                 }             });  } catch (exception e) {     runonuithread(new runnable() {                 @override                 public void run() {                     toast.maketext(context,e.getmessage(), toast.length_short).show();                 }             }); }
