i using asynctask class update 2 different tables on sql server far code works fine i'm interested in more better , sufficient code structure of class specially in doinbackground() okay call multiple webservices methods in single thread? can 1 suggest me? 

        private class update extends asynctask<void, void, integer> {         private final int failed_invalid_response = 0;         private final int success_get_data = 1;         progressdialog progress;         private string _phoneno;         private string _ticket;         updateticket(string phoneno,string ticket){             _phoneno=phoneno;             _ticket=ticket;         }         @override         protected void onpreexecute() {             super.onpreexecute();             progress = progressdialog.show(xyz.this, "",                     "in progress...", false);         }          @override         protected integer doinbackground(void... params) {             method1(_phoneno);             return  method2(_phoneno,_ticket);         }         @override         protected void onpostexecute(integer result) {             progress.dismiss();             switch (result) {                 case failed_invalid_response:                     toast.maketext(xyz.this,"please check internet connection.",toast.length_short).show();                     break;                 case success_get_data:                     toast.maketext(xyz.this, "success!", toast.length_short).show();                     break;             }         }         int  method1(string phoneno,string tickets)         {             final  string methodname = "firstmethod";             final  string namespace ="http://tempuri.org/";             final  string url="www.sampleurl.com";             final  string soap_action="http://tempuri.org/firstmethod";             int success=0;             strictmode.threadpolicy policy = new strictmode.threadpolicy.builder().permitall().build();             strictmode.setthreadpolicy(policy);             soapobject request = new soapobject(namespace, methodname);             soapserializationenvelope envelope = new  soapserializationenvelope(soapenvelope.ver11);             envelope.dotnet = true;             request.addproperty("phoneno", phoneno);             request.addproperty("tickets", tickets);             envelope.setoutputsoapobject(request);              httptransportse androidhttptransport = new httptransportse(url);             try{                 androidhttptransport.call(soap_action,envelope);                 soapobject response = (soapobject) envelope.bodyin;             if(response!=null){                 success=1;             }             }             catch (exception e)             {                 e.printstacktrace();              }              return success;         }         int  method2(string phone) {             final  string methodname = "secondmethod";             final  string namespace ="http://tempuri.org/";             final  string url="www.sampleurl.com";             final  string soap_action="http://tempuri.org/secondmethod";             int success=0;             strictmode.threadpolicy policy = new strictmode.threadpolicy.builder().permitall().build();             strictmode.setthreadpolicy(policy);             soapobject request = new soapobject(namespace, methodname);             soapserializationenvelope envelope = new  soapserializationenvelope(soapenvelope.ver11);             envelope.dotnet = true;             request.addproperty("phoneno", phoneno);             envelope.setoutputsoapobject(request);             httptransportse androidhttptransport = new httptransportse(url);             try{                 androidhttptransport.call(soap_action,envelope);                 soapobject response = (soapobject) envelope.bodyin;             if(response!=null){                 success=1;             }             }             catch (exception e)             {                 e.printstacktrace();              }              return success;         }        }

asynctask should used tasks/operations take quite few seconds.

asynctasks executed serially on single background thread (from api 11). long running worker can block others.

check other gotchas.

take @ heandlerthread.
