Calling A Web Service From An Android Application

I am using the following code which i found on internet to call a web service from my android app: public class WebServiceActivity extends Activity { private static final Strin

Solution 1:

Put your web service request as a background task. Usually time taken by a network activity is unpredictable. If you use above, the UI Thread will block. That is why it says "Application not responding".

I found this great article. http://www.vogella.de/articles/AndroidPerformance/article.html#concurrency Have a look at 2. Background Processing

Your example can be modified as following.

publicclassWebServiceActivityextendsActivity {
    privatestaticfinalStringSOAP_ACTION="http://tempuri.org/HelloWorld";

    privatestaticfinalStringMETHOD_NAME="HelloWorld";

    privatestaticfinalStringNAMESPACE="http://tempuri.org/";
    privatestaticfinalStringURL="http://192.168.1.19/TestWeb/WebService.asmx";

    TextView result1;

    @OverridepublicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        result1 = (TextView) findViewById(R.id.result1);

        Buttongetquote= (Button) findViewById(R.id.getquote);
        getquote.setOnClickListener(newOnClickListener() {

            publicvoidonClick(View v) {

                // push soap request into background.newThread(newRunnable(){

                    @Overridepublicvoidrun() {
                        doSoapRequest();
                    }

                },"DOINBACKGROUND");
            }
        });

    }

    privatevoiddoSoapRequest(){
        try {

            SoapObjectrequest=newSoapObject(NAMESPACE, METHOD_NAME);
            EditTextCompanyName= (EditText) findViewById(R.id.CompanyName);
            Stringval1= (CompanyName.getText().toString());
            request.addProperty("passonString", val1);

            SoapSerializationEnvelopeenvelope=newSoapSerializationEnvelope(
                    SoapEnvelope.VER11);
            envelope.dotNet = true;
            envelope.setOutputSoapObject(request);

            HttpTransportSEandroidHttpTransport=newHttpTransportSE(
                    URL);
            androidHttpTransport.call(SOAP_ACTION, envelope);

            Objectresult= (Object) envelope.getResponse();

//          result1.setText(result.toString());//           update UI data in a HandlerMessagemsg=newMessage();
            msg.obj = result.toString();
            result1Handler.sendMessage(msg);
        } catch (Exception e) {

//          result1.setText(e.getMessage());//           update UI data in a HandlerMessagemsg=newMessage();
            msg.obj = e.getMessage();
            result1Handler.sendMessage(msg);
        }
    }

    privateHandlerresult1Handler=newHandler(){
        @OverridepublicvoidhandleMessage(Message msg) {
            super.handleMessage(msg);
            result1.setText(msg.obj.toString());
        }

    };

}
