Actually i got the correct answer. For nested request i wrote the below code and it worked.

   SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

  // Add input values to SOAPObject object - request
        request.addProperty("user_name", "test");
        request.addProperty("license_code",
                "test");
 // Add property for nested tags        
        PropertyInfo pi = new PropertyInfo();

        pi.setName("OCRWSSetting");
        pi.setValue(new SoapObject(NAMESPACE, "OCRWSSettings")
        .addProperty("ocrLanguages", "ENGLISH")
        .addProperty("outputDocumentFormat", "TXT")
        .addProperty("convertToBW", false)
        .addProperty("getOCRText", true)
        .addProperty("createOutputDocument", false)
        .addProperty("multiPageDoc", false)
        .addProperty("ocrWords", false));

        request.addProperty(pi);

    // Add property for another nested tags 

        pi = new PropertyInfo();
        pi.setName("OCRWSInputImage");
        pi.setValue(new SoapObject(NAMESPACE, "OCRWSInputImage")
        .addProperty("fileName", getString(R.string.file_name))
        .addProperty("fileData",base64String)
        );

        request.addProperty(pi);
