I'm implementing an AsyncTask, that calls a WCF service methods in the doInBackground method.
the WCF method name is a parameter for the doInBackground method.
I want the progress dialog to show only for specific methods name sent to doInBackground.
My porgressdialog setting are set in onPreExecute methods.
Any way to make progressdialog appear for a specific doInBackground parameter (wcf method name)
public class WCFHelper extends AsyncTask<Object, Void, String[]>{
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://url";
final ProgressDialog pd;
public Context ctx;
public WCFHelper(Context _ctx)
{ this.ctx = _ctx;
pd = new ProgressDialog(_ctx);
}
#Override
protected void onPreExecute() {
pd.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pd.setMessage("login...");
pd.setIndeterminate(true);
pd.setCancelable(false);
pd.show();
}
#Override
protected String[] doInBackground(Object... params) {
String WCFmethod = (String)params[0];
Map<String,Object> parameterArgs = (Map<String,Object>)params[1];
Boolean isArr = (Boolean)params[2];
String [] Fail = {"Fail"};
String SOAP_ACTION = "http://tempuri.org/IService1/"+WCFmethod;
String METHOD_NAME = WCFmethod;
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
for(Map.Entry<String,Object> entry: parameterArgs.entrySet())
request.addProperty(entry.getKey().toString(), entry.getValue().toString());
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
if(!isArr)
{
SoapPrimitive result = (SoapPrimitive)envelope.getResponse();
String[] toReturn = new String[1];
toReturn[0] = result.toString();
return toReturn;
}
else{
envelope.implicitTypes = true ;
SoapObject listDataSet = (SoapObject) envelope.bodyIn;
int numOfStrings = ((SoapObject)listDataSet.getProperty(0)).getPropertyCount();
String[] toReturn = new String[numOfStrings];
for ( int i = 0 ; i <numOfStrings; i++) {
toReturn[i] = ((SoapObject)listDataSet.getProperty(0)).getProperty(i).toString();
}
return toReturn;
}
}
catch (Exception e) {
return Fail;
}
}
protected void onPostExecute(String res) {
// TODO: check this.exception
// TODO: do something with the feed
if(this.pd.isShowing())
pd.dismiss();
}
As you can see one of the params for doInBackground is WCF method name.
I want the progressdialog to show only to specific WCF methods (received as parameter)
Send parameters also during instantiating the WCHelper object.
Keep a variable in the WCFHelper class.
public class WCFHelper extends AsyncTask<Object, Void, String[]>{
int val;
public WCHelper(int param) //constructor
{
super();
val = param; //now you can use this val in onPreExecute
}
...
}
Send the same parameter you wanted to send to onPreExecute(). For example,
WCHelper task = new WCHelper(param); // this sends value to constructor
task.execute(param); //this sends value to doInBackground
You can create your own custom constructor of the AsyncTask to transfer necessary parameter for handling the progress dialog.
private class MyTask extends AsyncTask<Void, Void, Void> {
public MyTask(boolean showProgress){
....
}
....
}

I want to return an array of strings to my Android client and populate a ListView.
I am using the SOAP library (org.ksoap2.*) to invoke an ASP.NET web service.
Here is the code for the web service:
1. ASP Web Service
Imports ...
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports ...
<WebService(Namespace:="...")>_
<WebService(ConformsTo:=...)> _
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Public Class EnquiryWS
Inherits System.Web.Services.WebService
' Web method
<WebMethod()> _
Public Function GetList() As String()
'Hardcoded list
Return New String() { "item1", "item2", "item3" }
End Function
I've tested the web service by accessing the asmx, there are no runtime errors.
I've also tested it with just a simple string, the web service returned the string to Android. Like this:
' Web method
<WebMethod()> _
Public Function GetString() As String
Return "My string."
End Function
2. Android Activity
Secondly, here is my Android code that is invoking the ASP.NET web service.
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
public class MainActivity extends AppCompatActivity {
private ArrayList<String> list;
private ListView listview;
private ArrayAdapter<String> adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
//...
new GetPersonList().execute("AsyncTask String");
//...
}
// Inner AsyncTask class
private class GetPersonList extends AsyncTask<String, Integer,String> {
private static final String SOAP_ACTION = "https://myNamespace/GetList";
private static final String METHOD_NAME = "GetList";
private static final String NAMESPACE = "https://myNamespace/";
private static final String URL =
"https://myIISsite/myASMXfile.asmx";
#Override
protected void onPreExecute() {
super.onPreExecute();
// onPreExecute stuff
}
#Override
protected String doInBackground(String... arg) {
String result = null;
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//Create envelope
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
//Required for .net
envelope.dotNet = true;
//Set output SOAP object
envelope.setOutputSoapObject(request);
//Create HTTP call object
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
//Invoke web service
androidHttpTransport.call(SOAP_ACTION, envelope);
//Get the response
SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
//Assign it to response to a static variable
result = response.toString();
} catch (Exception e) {
result = "error " + e.getMessage();
}
return result;
}
#Override
protected void onPostExecute(String result) {
System.out.println("Returned SOAP XML: " + result);
MyFunction(result);
}
}
}
MyFunction is a method that I created to do some additional work.
3. MyFunction
Here is MyFunction method code:
public void MyFunction(String s) {
// Add Webservice response to list
list.add(s);
// Set adapter
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item1, list);
listview.setAdapter(adapter);
}
The argument I pass to MyFunction is the SOAP response, I then add it to the list and set the adapter.
Okay, so the web service is returning an array of strings, but the overriden onPostExecute method is working with one string, if I declare the onPostExecute parameter as a Collection, it is obviously not overriding anymore.
This is the error that I am getting in logcat:
Return SOAP XML: error expected: START_TAG {http://schemas.xmlsoap.org/soap/envelope/}Envelope (position:START_TAG <html>#1:7 in java.io.InputStreamReader#4182d238)
Could anyone please advise?
I have found a solution. I am casting the response as a SoapObject and not as a SoapPrimitive, the reason for that is because a SoapPrimitive is for primitive data types, SoapObject supports composite data types. Therefore, I am casting my array as a SoapObject and not as a SoapPrimitive anymore.
I have removed the MyFunction() method, because I am setting the adapter in the onPostExecute() method by override run(). And finally, I have added a ProgressDialog, I am showing the ProgressDialog in the onPreExecute() method while it's processing, and then I am invoking dismiss() in the onPostExecute() method.
private class GetPersonList extends AsyncTask<Void, Void, String> {
private static final String SOAP_ACTION = "http://myNamespace/myMethod";
private static final String METHOD_NAME = "myMethod";
private static final String NAMESPACE = "http://myNamespace/";
private static final String URL =
"http://myURL/myAsmxFile.asmx";
ProgressDialog progressDialog;
#Override
protected void onPreExecute() {
super.onPreExecute();
progressDialog= ProgressDialog.show(MainActivity.this,
"Wait",
"Retrieving data",
true
);
}
#Override
protected String doInBackground(Void... params) {
String finalResult = null;
//Create request object
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//Create envelope to which we add our request object
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
//Required for .net
envelope.dotNet = true;
//Add the request object to the envelope
envelope.setOutputSoapObject(request);
//Create HTTP call object
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
//Invoke web service
androidHttpTransport.call(SOAP_ACTION, envelope);
// Get the response
// Cast as SoapObject and not SoapPrimitive
SoapObject response = (SoapObject) envelope.getResponse();
//Assign it to response to a static variable
finalResult = response.toString();
// Now loop through the response (loop through the properties)
// and add them to the list
for(int i = 0; i < response.getPropertyCount(); i++) {
list.add(response.getProperty(i).toString());
}
} catch (Exception e) {
System.out.println("######## ERROR " + e.getMessage());
}
return finalResult;
}
#Override
protected void onPostExecute(String str) {
progressDialog.dismiss();
System.out.println("Returned SOAP XML: " + str);
runOnUiThread(new Runnable() {
#Override
public void run() {
// Set adapter
adapter = new ArrayAdapter<String>(MainActivity.this, R.layout.list_item, R.id.product_name, list);
listview.setAdapter(adapter);
}
});
}
}
I have heard that there is another way of doing this using Gson/Json, I will post that once I have figured it out.

What i have is an asynctask that i use it to send data to web service which work just fine , and here is my web service code :
public class WebServiceDetails {
//Namespace of the Webservice - can be found in WSDL
private static String NAMESPACE = "http://tempuri.org/";
//Webservice URL - WSDL File location
//URL = "http://80.90.161.246:70/erP_Reporting/OrderAndroid.asmx";
private static String URL = "http://192.168.1.124/alibabanewwebservice/AliBabaWebService.asmx";//Make sure you changed IP address
//private static String URL = "http://192.168.1.103/webservicejal6ah/OrderAndroid.asmx";//Make sure you changed IP address
//SOAP Action URI again Namespace + Web method name
private static String SOAP_ACTION = "http://tempuri.org/InsertOrderDetails";
public static boolean invokeLoginWS(String DeviceId, String Item_id, String Item_Quantity,String Bounce,String webMethName)
{
boolean loginStatus = false;
// Create request
SoapObject request = new SoapObject(NAMESPACE, webMethName);
// Property which holds input parameters
PropertyInfo deviceid = new PropertyInfo();
PropertyInfo itemid = new PropertyInfo();
PropertyInfo quantity = new PropertyInfo();
PropertyInfo bounce= new PropertyInfo();
deviceid.setName("DeviceId");
deviceid.setValue(DeviceId);
deviceid.setType(String.class);
request.addProperty(deviceid);
itemid.setName("Item_id");
itemid.setValue(Item_id);
itemid.setType(String.class);
request.addProperty(itemid);
quantity.setName("Item_Quantity");
quantity.setValue(Item_Quantity);
quantity.setType(String.class);
request.addProperty(quantity);
bounce.setName("Bounce");
bounce.setValue(Bounce);
bounce.setType(String.class);
request.addProperty(bounce);
// extra.setName("Extra");
// extra.setValue(Extra);
// extra.setType(String.class);
// request.addProperty(extra);
// Create envelope
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(1);
envelope.dotNet = true;
// Set output SOAP object
envelope.setOutputSoapObject(request);
// Create HTTP call object
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
// Invoke web service
androidHttpTransport.call(SOAP_ACTION, envelope);
// Get the response
// SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
Object response = (Object) envelope.getResponse();
// Assign it to boolean variable variable
loginStatus = Boolean.parseBoolean(response.toString());
} catch (Exception e) {
//Assign Error Status true in static variable 'errored'
e.printStackTrace();
}
//Return booleam to calling object
return loginStatus;
}
}
And here is my asynctask :
private class AsyncCallWS extends AsyncTask<Void, Void, Void> {
protected void onPostExecute(Void result) {
super.onPostExecute(result);
Log.e("Customer_Name","sereen");
//Make Progress Bar invisible
//AddToCart.cartlist.clear();
try{
//Log.e(" Customer_Id=masterrs.get(m).getCustomerId()", rs.get(m).getCustomerId());
Toast.makeText(CartList.this, "order has been send ", Toast.LENGTH_LONG).show();
}
catch(Exception e){
e.printStackTrace();
}
}
//Make Progress Bar visible
protected void onPreExecute() {
super.onPreExecute();
pd.setTitle("sending");
pd.setMessage("waiting...");
pd.show();
}
#Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
loginStatus2 = WebServiceDetails.invokeLoginWS(Device_ID,Item_Id,Quantity,Bounce,"InsertOrderDetails");
Log.e("Device_ID details",Device_ID+"");
// try{
//Log.e(" Customer_Id=masterrs.get(m).getCustomerId()", rs.get(m).getCustomerId());
// }
// catch(Exception e){
// e.printStackTrace();
// }
//
// }
}
return null;
}
}
well , the problem is as you can see my asynctask return null value and i want it after i send value to return true for (loginStatus2) but the thing is when i tried to do it , it didn't work .. can anyone help me , what shall i change to get the value true when success post on web service and false when it fails?
Try this code for AsyncTask. Use result and check if it is null or not.
If null, there is no response else you can have response in form of result from Asynctask() method.
private class AsyncCallWS extends AsyncTask<Void, Void, String> {
String response;
protected void onPostExecute(String result) {
super.onPostExecute(result);
if(result==null){
Toast.makeText(CartList.this, "result is null", Toast.LENGTH_LONG).show();
}else{
Toast.makeText(CartList.this, "Result is: "+ result, Toast.LENGTH_LONG).show();
}
try{ //Your code here
//Log.e(" Customer_Id=masterrs.get(m).getCustomerId()", rs.get(m).getCustomerId());
Toast.makeText(CartList.this, "order has been send ", Toast.LENGTH_LONG).show();
}
catch(Exception e){
e.printStackTrace();
}
}
//Make Progress Bar visible
protected void onPreExecute() {
super.onPreExecute();
pd.setTitle("sending");
pd.setMessage("waiting...");
pd.show();
}
#Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
loginStatus2 = WebServiceDetails.invokeLoginWS(Device_ID,Item_Id,Quantity,Bounce,"InsertOrderDetails");
response = loginStatus2;
Log.e("Device_ID details",Device_ID+"");
}
return response;
}
}
Tried using Async but got can't handler even there is no toast in it,
also tried call calling method runUIThread but no luck ,
Async method works but it also gets run time exception
when i use Async method data gets on the Textview too late (5-10 mins) , but when i use it in debuggers it gets instantly ,
below webservice is test using wizdl application and response is instant
i'm confused please help
private final String NAMESPACE = "http://????????.com/EventGetter/";

//Invole web service
androidHttpTransport.call(SOAP_ACTION, envelope);
//Get the response
SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
//Assign it to Text static variable
text.setText(response.toString());
} catch (Exception e) {
e.printStackTrace();
}
}
also tried calling get data in oncreate method
NotifyList.this.runOnUiThread(new Runnable() {
#Override
public void run() {
GetData();
// TPaccessData task = new TPaccessData();
// task.execute();
}
});
Remove youe GetData() method from onPreExecute()
and call this line inside onPost
text.setText(response.toString());
I have a simple android application to access a web service. I want to show a dialog "Loading . . ." until results are loaded and dismissed after loading the results. I have used this code but this doesn't show the loading message:
public class LoadingActivity extends Activity {
private static final String SOAP_ACTION = "http://ws.eretailer.com/";
private static final String METHOD_NAME = "dataSender";
private static final String NAMESPACE = "http://ws.eretailer.com/dataSender/";
private static final String URL = "http://175.157.128.207:8085/Eretailer/services/EretailerService?wsdl";
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final ProgressDialog pd = new ProgressDialog(this);
pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
pd.setMessage("Loading. . .");
pd.show();
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
pd.show();
HttpTransportSE ht = new HttpTransportSE(URL);
try {
ht.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
SoapPrimitive s = response;
pd.dismiss();
String str = s.toString();
String arr1[] = str.split(" ");
TextView tv = new TextView(this);
for(int i = 0; i<arr1.length;i++){
tv.append("order ID :"+arr1[i]+"\n");
}
setContentView(tv);
} catch (Exception e) {
e.printStackTrace();
}
}
}
How can I correct this problem ?

Better to use Android-AsyncTask for your Web Request. And start ProgressDialog in onPreExecute() of AsyncTask and close it in onPostExecute()(Update your UI here for result from Web response). Also put Web-Request code in doInBackGround() of AsyncTask..
For Example look at Android AsyncTask Example.
This will never block your Main-UI Thread. And better performance for User Experience.
first comment pd.dismiss() first and check if its loading is coming then use pd.dismiss() after downloading complete.
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.
