Soap request creation using ksoap2 for multilevel tags

I want to build a soap request using KSOAP2 for android application. how to create a request for the given below soap request.
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:glob="http://sap.com/xi/SAPGlobal20/Global"
xmlns:yrt="http://0021611689-one-off.sap.com/YRTWIVFXY_"
xmlns:ytk="http://0021611689-one-off.sap.com/YTK2PLNNY_"
xmlns:glob1="http://sap.com/xi/AP/Globalization">`
<soapenv:Header/>
<soapenv:Body>
<glob:CustomerBundleMaintainRequest_sync_V1>
<BasicMessageHeader>
</BasicMessageHeader>
<Customer>
<InternalID>234569</InternalID>
<!--Optional:-->
<CategoryCode>1</CategoryCode>
<CustomerIndicator>true</CustomerIndicator>
<!--Optional:-->
<LifeCycleStatusCode>2</LifeCycleStatusCode>
<!--Optional:-->
</Customer>
</glob:CustomerBundleMaintainRequest_sync_V1>
</soapenv:Body>
</soapenv:Envelope>
I have written the Android code and tried to build the request it shows an error that Soapfault message error. Find below the android code
public class CreateCustomer {
public void createCustomerAccount() throws IOException {
SoapObject soapObject = new SoapObject(NAME_SPACE,METHOD_NAME);
soapObject.addProperty("InternalID","98765");
soapObject.addProperty("CategoryCode","1");
soapObject.addProperty("CustomerIndicator","true");
soapObject.addProperty("LifeCycleStatusCode","2");
}

For Building soap request ..
public String sendSoapRequest(Context c) throws Exception {
String finalString = "Paste your whole request through which you can send request from browser sucessfully";
Log.i("TAG", "*********************** FinalString Before "
+ FinalString);
// send SOAP request
InputStream resInputStream = sendRequest(FinalString);
// create the response SOAP envelope
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
// process SOAP response
parseResponse(resInputStream, envelope);
Object bodyIn = envelope.bodyIn;
SoapObject RequestSOAP = (SoapObject) envelope.bodyIn;
String response = RequestSOAP.getProperty(0).toString();
if (bodyIn instanceof SoapFault) {
throw (SoapFault) bodyIn;
}
return response.toString();
}
calling sendRequest ..
private InputStream sendRequest(String requestContent) throws Exception {
// initialize HTTP post
HttpPost httpPost = null;
try {
httpPost = new HttpPost(PostURL);
httpPost.addHeader("Content-Type", "text/xml;charset=UTF-8");
httpPost.addHeader("SOAPAction", "Your Soap Action");
} catch (Throwable e) {
Log.e("LOG_TAG", "Error initializing HTTP post for SOAP request", e);
// throw e;
}
// load content to be sent
try {
HttpEntity postEntity = new StringEntity(requestContent);
httpPost.setEntity(postEntity);
} catch (UnsupportedEncodingException e) {
Log.e("LOG_TAG",
"Unsupported ensoding of content for SOAP request", e);
throw e;
}
// send request
HttpResponse httpResponse = null;
HttpClient httpClient = new DefaultHttpClient();
try {
httpResponse = httpClient.execute(httpPost);
} catch (Throwable e) {
Log.e("LOG_TAG", "Error sending SOAP request", e);
// throw e;
}
// get SOAP response
try {
// get response code
int responseStatusCode = httpResponse.getStatusLine()
.getStatusCode();
// if the response code is not 200 - OK, or 500 - Internal error,
// then communication error occurred
if (responseStatusCode != 200 && responseStatusCode != 500) {
String errorMsg = "Got SOAP response code "
+ responseStatusCode + " "
+ httpResponse.getStatusLine().getReasonPhrase();
// ...
}
// get the response content
HttpEntity httpEntity = httpResponse.getEntity();
InputStream is = httpEntity.getContent();
return is;
} catch (Throwable e) {
Log.e("LOG_TAG", "Error getting SOAP response", e);
// throw e;
}
return null;
}
call parseResponse
/**
* Parses the input stream from the response into SoapEnvelope object.
*/
private void parseResponse(InputStream is, SoapEnvelope envelope)
throws Exception {
try {
XmlPullParser xp = new KXmlParser();
xp.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, true);
xp.setInput(is, "UTF-8");
envelope.parse(xp);
} catch (Throwable e) {
Log.e("LOG_TAG", "Error reading/parsing SOAP response", e);
}
}
call SendOrderDetails...
private class SendOrderDetails extends AsyncTask<String, CartViewItemsBean, String> {
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected String doInBackground(String... arg) {
String fdfd = "";
try {
fdfd = sendSoapRequest(getActivity());
} catch (Exception e) {
e.printStackTrace();
}
return fdfd;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
Log.i("transactionresponse", result);
if (!result.equalsIgnoreCase("")) {
try {
helpher.deleteTotalRecord();
String ffsd = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" + result.toString();
XmlToJson xmlToJson = new XmlToJson.Builder(ffsd.trim()).build();
JSONObject jsonObject = xmlToJson.toJson();
} catch (Exception e) {
e.printStackTrace();
}
} else {
}
}
}
And you have to use library XmlToJson
finally you have to call this using
new SendOrderDetails().execute();

KSOAP2 add array to soap request

I'm trying to connect with a web service.
The sample request for this web service contains this array:
<Details>
<invoiceDetails>
<ItemID>int</ItemID>
<Price>decimal</Price>
<Quantity>decimal</Quantity>
<UOM>int</UOM>
</invoiceDetails>
<invoiceDetails>
<ItemID>int</ItemID>
<Price>decimal</Price>
<Quantity>decimal</Quantity>
<UOM>int</UOM>
</invoiceDetails>
</Details>
I have managed to make a call with SOAP before, but not with arrays,
so how would I add this to my request?

Try this code,
public String getservicecallmethod(String nameSpace, String methodName,
String soapAction, String Url, List<Info> mInfo) {
String mResponse = "";
SoapObject request = new SoapObject(nameSpace, methodName);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
if (mPropertyInfo != null) {
for (Info propertyInfo : mInfo) {
request.addProperty(propertyInfo);
}
}
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE ht = new HttpTransportSE(Url);
ht.debug = true;
try {
ht.call(soapAction, envelope);
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
try {
mResponse = envelope.getResponse().toString();
} catch (Exception e) {
e.printStackTrace();
}
return mResponse;
}

where is the wrong in this syntax of calling http request get

I have this call (from the browser)
http://serverName:8081/cmp-mg-?sub_x?=7
and it returns 200 response
and I want to call do that request from my web service:
this is my web service:
public Response sendMT2(#BeanParam MT mt) throws IOException {
try {
HttpHost host = new HttpHost("serverName", 8081);
HttpClient client = HttpClientBuilder.create().build();
HttpRequest request = new BasicHttpRequest("GET",
"/serverp/sam?" + mt.getURLParameter());
System.out.println("/cmp-mg-xconn-http-webapp/sam?"
+ mt.getURLParameter());
HttpResponse response = client.execute(host, request);
String responseString = new BasicResponseHandler()
.handleResponse(response);
return Response.ok(responseString).build();
} catch (ClientProtocolException e) {
throw e;
// return Response.status(500).build();
} catch (IOException e) {
throw e;
// return Response.status(500).build();
}
}
but I am getting error
org.apache.http.client.HttpResponseException: Not Found
what is the wrong?

I found the error myself.

Android - How to Handle an Async Http Crash

My app is currently crashing whenever it cannot connect to the server. How do I handle this, and instead let the user know that the server is down and to try again.
private void sendPostRequest(String givenEmail, String givenPassword) {
class SendPostRequestTask extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... params) {
String emailInput = params[0];
String passwordInput = params[1];
String jsonUserInput = "{email: " + emailInput + ", password: "
+ passwordInput + "}";
try {
HttpClient httpClient = new DefaultHttpClient();
// Use only the web page URL as the parameter of the
// HttpPost argument, since it's a post method.
HttpPost httpPost = new HttpPost(SERVER_URL);
// We add the content that we want to pass with the POST
// request to as name-value pairs
json = new JSONObject(jsonUserInput);
jsonString = new StringEntity(json.toString());
httpPost.setEntity(jsonString);
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-type", "application/json");
HttpParams httpParameters = httpPost.getParams();
// Set the timeout in milliseconds until a connection is established.
int timeoutConnection = 1000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
// Set the default socket timeout (SO_TIMEOUT)
// in milliseconds which is the timeout for waiting for data.
int timeoutSocket = 1000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
// HttpResponse is an interface just like HttpPost.
// Therefore we can't initialize them
HttpResponse httpResponse = httpClient.execute(httpPost);
// According to the JAVA API, InputStream constructor does
// nothing.
// So we can't initialize InputStream although it is not an
// interface
InputStream inputStream = httpResponse.getEntity()
.getContent();
InputStreamReader inputStreamReader = new InputStreamReader(
inputStream);
BufferedReader bufferedReader = new BufferedReader(
inputStreamReader);
StringBuilder stringBuilder = new StringBuilder();
String bufferedStrChunk = null;
while ((bufferedStrChunk = bufferedReader.readLine()) != null) {
stringBuilder.append(bufferedStrChunk);
}
return stringBuilder.toString();
} catch (ClientProtocolException cpe) {

LogCat Error Log

I can see that you are already catching the Exceptions and have a String as parameter type to onPostExecute. From inside the exceptions, you can pass a string like "error" to the onPostExecute, whenever an error occurs. Inside the onPostExecute you can check:
if the string is equal to "error":
then create a Alert dialog box from within `onPostExecute` and show it.
else:
continue as desired
Ideally a boolean would do the trick but since you already have a string, you can also use that. Otherwise you can have a struct with a string and a boolean and then pass it to onPostExecute. Hope it gives you the idea.

Or you can create new Object
public class AsyncTaskResult<T> {
private T result;
private Exception error;
public T getResult() {
return result;
}
public Exception getError() {
return error;
}
public AsyncTaskResult(T result) {
super();
this.result = result;
}
public AsyncTaskResult(Exception error) {
super();
this.error = error;
}
public void setError(Exception error) {
this.error = error;
}
}
and pass it to onPostExecute
return new AsyncTaskResult<String>(result)
or
return new AsyncTaskResult<String>(exception)
in onPostExecute you may check exception exists or not
asynctaskresult.getError() != null

You can use droidQuery to simplify everything and include HTTP error handling:
$.ajax(new AjaxOptions().url("http://www.example.com")
.type("POST")
.dataType("json")
.header("Accept", "application/json")
.header("Content-type", "application/json")
.timeout(1000)
.success(new Function() {
#Override
public void invoke($ d, Object... args) {
Toast.makeText(this, "SUCCESS!", Toast.LENGTH_SHORT).show();
JSONObject serverResponse = (JSONObject) args[0];
//handle response
}
})
.error(new Function() {
#Override
public void invoke($ d, Object... args) {
AjaxError error = (AjaxError) args[0];
//toast shows the error code and reason, such as "Error 404: Page not found"
Toast.makeText(this, "Error " + error.status + ": " + error.reason, Toast.LENGTH_SHORT).show();
}
}));
