Android: How to use ksoap2-android? -

i'm using webservice w3school testing, , have method:

public static float getcelsius(int fahrenheit) {     string soap_action = "http://www.w3schools.com/xml/fahrenheittocelsius";     string method_name = "fahrenheittocelsius";     string namespace = "http://www.w3schools.com/xml/";     string url = "http://www.w3schools.com/xml/tempconvert.asmx";      soapobject request = new soapobject(namespace, method_name);     request.addproperty("fahrenheit", fahrenheit);      soapserializationenvelope envelope = new soapserializationenvelope(soapenvelope.ver11);     envelope.dotnet = true;     envelope.setoutputsoapobject(request);      try {         httptransportse transport = new httptransportse(url);         transport.call(soap_action, envelope);          soapprimitive result = (soapprimitive)envelope.getresponse();         return float.parsefloat(result.tostring());      } catch(exception e) {         return 0;     } } 

but doesn't works, returns 0. set internet permission in androidmanifest.xml this:

<uses-permission android:name="android.permission.internet" /> 

i'm using avd emulator, tried running app in tablet: didn't work.

any help? sorry bad english, hope understand.

here's solution:

you can't run code on main thread, have create thread this:

thread thread = new thread() {     @override     public void run() {         string soap_action = "http://www.w3schools.com/xml/fahrenheittocelsius";         string method_name = "fahrenheittocelsius";         string namespace = "http://www.w3schools.com/xml/";         string url = "http://www.w3schools.com/xml/tempconvert.asmx";          soapobject request = new soapobject(namespace, method_name);         request.addproperty("fahrenheit", "10");          soapserializationenvelope envelope = new soapserializationenvelope(soapenvelope.ver11);         envelope.dotnet = true;         envelope.setoutputsoapobject(request);          try {             httptransportse transport = new httptransportse(url);             transport.call(soap_action, envelope);             soapprimitive result = (soapprimitive) envelope.getresponse();         } catch (exception e) {             log.e("tests", "ksoap2", e);         }     } }; thread.start(); 

anyway, answers.
