thank you
Your urls were a bit wrong. This is what I used,
protected String namespace = "http://www.nourhan-m.somee.com/";
protected String url = "http://www.nourhan-m.somee.com/WebService1.asmx";
protected String SOAPAction = "http://www.nourhan-m.somee.com/get_name";
protected String method_name = "get_name";
I made some modification to your code to make it work.
public String callService(String username) {
//create soap object and add params to it
SoapObject request = new SoapObject(namespace, method_name);
request.addProperty("pssw", username);
//create envelop
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
//set request to envelope
envelope.bodyOut = request;
HttpTransportSE transport = new HttpTransportSE(url);
transport.debug = true;
try {
transport.call(SOAPAction, envelope);
Log.e("OUT", transport.requestDump);
return transport.responseDump;
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
} catch (Exception e){
e.printStackTrace();
}
return "";
}
This is how I invoked the method,
You can invoke it as follows,
final String username = (TextView) findViewById(R.id.textView1)
new Thread(new Runnable() {
#Override
public void run() {
Log.e("OUT", callService(username));
}
}).start();
I got an empty response, maybe it's because I didn't give a valid username. Have a look at it. Cheers :)
What I am trying to do is create a simple Web Service in ASP.NET and get Data from MSSQL server through that web service and use that data in my android application. As a novice, I have tried out this Helpful link to follow. I have used the same architecture as this tutorial suggest. But getting error in parsing the result (Soap Response) in my result. It is as below.
<?xml version="1.0" encoding="utf-8"?> <soap:Envelope
> xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
> xmlns:xsd="http://www.w3.org/2001/XMLSchema">
> <soap:Body><findContactResponse xmlns="http://tempuri.org/" />
> </soap:Body> </soap:Envelope>
and the GetPropertyCount() method is returning 0, on the other hand, arrayindexoutofBound error is coming up with index 0.
Here is my activity code. Where I have implemented async task for easy handling.
public class MainActivity extends Activity {
/** Called when the activity is first created. */
private static final String SOAP_ACTION = "http://tempuri.org/findContact";
private static final String OPERATION_NAME = "findContact";// your webservice web method name

propertyInfo.type = PropertyInfo.STRING_CLASS;
propertyInfo.name = "eid";
Log.e("studentNo", studentNo);
request.addProperty(propertyInfo);
request.addProperty("eid", studentNo);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

}

}
}
catch (Exception exception) {

int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**

*/
}
Now can anyone just show me what went wrong for me? Or how can I get my response without exception? After debugging I came up with this line which is creating exceptions.
String resultData=result.getProperty(0).toString();
Thanks is advance for any kind of help.
Finally figured it out.
It was in adding property. And slightly changing the response parsing.
Here is the complete code which worked out for me.
Hope it helps others.

}
return state;

I have implemented an async task as well to get rid of run time exceptions on Main thread. Need to add the request.addProperty(propertyInfo) properly.

Try to add "" to your SOAP_ACTION:
final String SOAP_ACTION = "\"http://tempuri.org/InsertAppointment\"";
I'm coding an app that primarily uses data gotten from a web service, and I want to use AsyncTask to run the SOAP calls in the background... I'm fairly new to Android(being an iOS programmer), so I'm a bit new at this...
Now, I have a login screen, where I take a user-provided login and check it against information on a server...
So in my login activity:
loginBtn.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
//Run the connection to authenticate the user
AuthenticateConnection mAuth = new AuthenticateConnection();
mAuth.mNumber = number;
mAuth.mPassword = pass;
mAuth.connection();
}
}
and my soap class is this:
public class AuthenticateConnection
{
private static final String SOAP_ACTION = "http://tempuri.org/Authenticate";
private static final String METHOD_NAME = "Authenticate";
private static final String NAMESPACE = "http://tempuri.org/";
private String URL;
public Boolean userOK;
public String mNumber;
public String mPassword;
public AuthenticateConnection()
{
}
public void connection()
{
Singleton service = Singleton.getInstance();
String firstURL = service.getURL();
URL = firstURL + "Parent.svc";
System.out.println("Connection to: " + URL);
//Initialize soap request
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//Add parameters
request.addProperty("login", mNumber);
request.addProperty("password", mPassword);
//Declare the version of the SOAP request
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.implicitTypes=true;
envelope.setAddAdornments(false);
//Prepare request
envelope.setOutputSoapObject(request);
//Needed to make the internet call
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
//Allow for debugging - needed to output the request
androidHttpTransport.debug = true;
try
{
//this is the actual part that will call the web service
androidHttpTransport.call(SOAP_ACTION, envelope);
//Get the SoapResult from the envelope body.
//Object result = envelope.getResponse();
//Object result = envelope.bodyIn;
SoapObject sResult = (SoapObject)envelope.bodyIn;
String tempID = sResult.getProperty("AuthenticateResult").toString();
//Check if the user exists and has the correct password
if(tempID != "-1")
{
userOK = true;
//Store the values in the singleton class
service.parentID = sResult.getProperty("AuthenticateResult").toString();
service.parentToken = sResult.getProperty("token").toString();
}
//If -1 is returned, then either the number or the password is incorrect
else
{
userOK = false;
}
} catch(org.xmlpull.v1.XmlPullParserException ex2)
{
//System.out.println(androidHttpTransport.requestDump.toString());
} catch (Exception e)
{
e.printStackTrace();
System.out.println(androidHttpTransport.requestDump.toString());
}
}
}
So my question is, how would I do this with AsyncTask?
I've been looking at some tutorial on AsyncTask, but haven't really "gotten it" so far...
You can do:
private class ConnectionTask extends AsyncTask<String, Void, Void> {
private ProgressDialog dialog = new ProgressDialog(ACTIVITY_NAME.this);
protected void onPreExecute() {
dialog.setMessage("Connecting...");
dialog.show();
}
protected void doInBackground(String... args) {
AuthenticateConnection mAuth = new AuthenticateConnection();
mAuth.mNumber = args[0];
mAuth.mPassword = args[1];
mAuth.connection();
}
protected void onPostExecute(Void v) {
if (dialog.isShowing()) {
dialog.dismiss();
}
}
}
And then call it:
loginBtn.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
//Run the connection to authenticate the user
new ConnectionTask().execute(number, pass);
}
}
Your connection method in AuthenticateConnection should return something to ensure the user has been authenticated. Then you can use that value in the onPostExecute, something like this:
protected void onPostExecute(Integer res) {
if (dialog.isShowing()) {
dialog.dismiss();
}
if (res.intValue() == OK) {
/* Maybe start a new Activity ...*/
} else {
/* Maybe show a Toast with an error message ...*/
}
}
In this case the signature of the asynctask will change:
private class ConnectionTask extends AsyncTask<String, Void, Integer>
and the doInBackground should return an Integer.
Hope it helps.
