I am having a problem using ksoap2 in android.
I used ksoap to communicate with the web service, but it gave me the following error. The code and exception log cat are below. It gives me that exception on the first line of the try block in my code.Could you help me please.
Activity Class:
public class MainActivity extends Activity {
public final static String URL = "http://10.0.2.2:8081/Service/services/SqlService.SqlServiceHttpSoap11Endpoint/";
public static final String NAMESPACE = "http://services.com";
public static final String SOAP_ACTION= "http://services.com/locationData";
private static final String METHOD_NAME = "locationData";
String str = null;
TextView t;
String longitude;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
t = (TextView) findViewById(R.id.textView1);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("message","Hello");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
} catch (HttpResponseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
SoapPrimitive result;
try {
result = (SoapPrimitive)envelope.getResponse();
String strRes = result.toString();
String resultArr[] = strRes.split("&");
longitude = resultArr[0];
t.setText(resultArr[0]);
} catch (SoapFault e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void sendLocation(View v){
Intent intent = new Intent(MainActivity.this,MappingActivity.class);
intent.putExtra("longitude",longitude);
startActivity(intent);
}
}
