web services - How can I make the url configurable in the ksoap Android-studio? -

i want configurable url , , user can change running application

public string namespace ="http://tempuri.org/"; public string url; // **how can make url configurable** public int timeout = 60000; public iwsdl2codeevents eventhandler; public soapprotocolversion soapversion; 

i try session variable , external file, , sqlite when trying call process , tell parameter method , give value url extracting database , application stops.

this geturl

public string geturl() {     string url = null;      sqlitehelper sql = new sqlitehelper(voceo.this,             "servicioweb", null, 1);     sqlitedatabase bd = sql.getwritabledatabase();     cursor fila = bd.rawquery(" select url direcciones idurl= 0", null);     if (fila.movetofirst()) {        url = fila.getstring(0);     }     bd.close();     return url; } 

and when try call him

public vectorstring obtenerpuertas(list<headerproperty> headers){     soapserializationenvelope soapenvelope = new soapserializationenvelope(soapenvelope.ver11);     soapenvelope.implicittypes = true;     soapenvelope.dotnet = true;     soapobject soapreq = new soapobject("http://tempuri.org/","obtenerpuertas");     soapenvelope.setoutputsoapobject(soapreq);     httptransportse httptransport = new httptransportse(geturl(),timeout); // **here try**     try{         if (headers!=null){             httptransport.call("http://tempuri.org/obtenerpuertas", soapenvelope,headers);         }else{             httptransport.call("http://tempuri.org/obtenerpuertas", soapenvelope);         }         object retobj = soapenvelope.bodyin;         if (retobj instanceof soapfault){             soapfault fault = (soapfault)retobj;             exception ex = new exception(fault.faultstring);             if (eventhandler != null)                 eventhandler.wsdl2codefinishedwithexception(ex);         }else{             soapobject result=(soapobject)retobj;             if (result.getpropertycount() > 0){                 object obj = result.getproperty(0);                 soapobject j = (soapobject)obj;                 vectorstring resultvariable = new vectorstring(j);                 return resultvariable;             }         }     }catch (exception e) {         if (eventhandler != null)             eventhandler.wsdl2codefinishedwithexception(e);         e.printstacktrace();     }     return null; } 

what doing wrong?

you can store url in preference.

create preference screen preference.xml:

<preferencescreen xmlns:android="http://schemas.android.com/apk/res/android">       <edittextpreference         android:capitalize="words"         android:defaultvalue="@string/pref_ip_default_value"     <------- add string in strings values (the default value ip)         android:inputtype="textcapwords"         android:key="@string/pref_ip_key"        <------- add string in strings values (key retrieve ip)         android:maxlines="1"         android:selectallonfocus="true"         android:singleline="true"         android:title="@string/pref_title_ip" <------- add string in strings values (the label show user)  />   </preferencescreen> 

settingsactivity.java:

public class settingsactivity extends preferenceactivity         implements preference.onpreferencechangelistener {     @override     public void oncreate(bundle savedinstancestate){         super.oncreate(savedinstancestate);         addpreferencesfromresource(r.xml.pref_general);         bindpreferencesummarytovalue(findpreference(getstring(r.string.pref_ip_key)));             }      }      private void bindpreferencesummarytovalue(preference preference) {         preference.setonpreferencechangelistener(this);          onpreferencechange(preference, preferencemanager                 .getdefaultsharedpreferences(preference.getcontext())                 .getstring(preference.getkey(), ""));      }       @override     public boolean onpreferencechange(preference preference, object value) {         string stringvalue = value.tostring();         preference.setsummary(stringvalue);            return true;     } } 

and in task.java:

 sharedpreferences preferences = preferencemanager.getdefaultsharedpreferences(actvitycontext);   // <---- preferences manager  string pref_key = actvitycontext.getstring(r.string.pref_ip_key);     // <------ name of preference   string pref_default = actvitycontext.getstring(r.string.pref_ip_default_value);     //  < ---- value variable  string preferedurl = preferences.getstring(pref_key, pref_default);    //   <------- user defined string   uri builduri = uri.parse(preferedurl).buildupon().build(); // <----- can build uri or wherever want
