How can I convert InputStream data to String in Android SOAP Webservices

Posted by: admin June 15, 2020 Leave a comment


When I am consuming the soap web services from Android I want to display the result in output string how can I convert that Input Stream to Sting?

  package com.venkattt.pack;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.SocketException;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;

import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.AndroidHttpTransport;
import org.ksoap2.transport.HttpTransportSE;
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserFactory;

import android.app.Activity;
import android.os.Bundle;

public class SoapWebservicesExampleActivity extends Activity {
    /** Called when the activity is first created. */
      final String NAMESPACE = "urn:sap-com:document:sap:soap:functions:mc-style";
     final String URL = "http://**********:8000/sap/bc/srt/wsdl/srvc_14DAE9C8D79F1EE196F1FC6C6518A345/wsdl11/allinone/ws_policy/document?sap-client=800&sap-user=************&sap-password=*********";
      final String METHOD_NAME = "Z_GET_CUST_GEN";
     final String SOAP_ACTION = "urn:sap-com:document:sap:soap:functions:mc-style/Z_GET_CUST_GEN";
    public void onCreate(Bundle savedInstanceState) {
           SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); // set up
            request.addProperty("Input", "1460");
            request.addProperty("Langu", "d");
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12); // put all required data into a soap
            envelope.dotNet = true;
            HttpTransportSE httpTransport = new HttpTransportSE(URL);
            httpTransport.debug = true;

            try {

                 httpTransport.call(SOAP_ACTION, envelope);
                 SoapObject response = (SoapObject)envelope.getResponse();
                 String str = response.getProperty(0).toString();


            catch(SocketException ex){

                } catch (Exception e) {


my final code please look at once and let me know

where can I put that conversion in the above code?

How to&Answers:
   String  response = convertStreamToString(instream);


private String convertStreamToString(InputStream is) {
    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    StringBuilder sb = new StringBuilder();

    String line = null;
    try {
        while ((line = reader.readLine()) != null) {
    } catch (IOException e) {
    } finally {
        try {
        } catch (IOException e) {
    return sb.toString();


Reading lines (both \n and \r; no distinctions) can make a mess. To get a String from an InputStream, I suggest you copy/paste the following method and call it wherever you need it.

public static String getStringFromInputStream(InputStream stream, String charsetName) throws IOException
    int n = 0;
    char[] buffer = new char[1024 * 4];
    InputStreamReader reader = new InputStreamReader(stream, charsetName);
    StringWriter writer = new StringWriter();
    while (-1 != (n = reader.read(buffer))) writer.write(buffer, 0, n);
    return writer.toString();


Based on Shane McC article you can using this method:

public String readFully(InputStream entityResponse) throws IOException {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
int length = 0;
while ((length = entityResponse.read(buffer)) != -1) {
    baos.write(buffer, 0, length);
return baos.toString();


import com.google.android.gms.common.util.IOUtils;

InputStream input = getInputStream();
String body = new String(IOUtils.toByteArray(input), "UTF-8");


You can try this way:

SoapObject response = (SoapObject)envelope.getResponse();
String str = response.getProperty(0).toString();

str will hold the content, you need to parse it further depending upon the requirement.
Also, please look this link as well there is a link how to parse it.


Try using soap VER11 instead of VER12 as this is giving error.

SoapSerializationEnvelope envelope = new  SoapSerializationEnvelope(SoapEnvelope.VER11); 

// put all required data into a soap

More information can be had about this from this link:


You can use:

String response = org.apache.commons.io.IOUtils.toString(instream, "UTF-8");

You need to add org.apache.commons.io.jar to your build path.
