You can also manually construct the request XML, and send it to kSOAP for sending and response processing. You can write your request XML using soapUI, then save them in res/raw with keywords like {%key%} where parameters should be placed at runtime.
Here is the code for replacing the keywords:
// parse the template and replace all keywords
StringBuffer sb = new StringBuffer();
try {
// find all keywords
Pattern patern = Pattern.compile("\\{%(.*?)%\\}");
Matcher matcher = patern.matcher(templateHtml);
while (matcher.find()) {
String keyName = matcher.group(1);
String keyValue = values.get(keyName);
if (keyValue == null) {
keyValue = "";
}
// replace the key with value
matcher.appendReplacement(sb, keyValue);
}
matcher.appendTail(sb);
// return the final string
return sb.toString();
} catch (Throwable e) {
Log.e(LOG_TAG, "Error parsing template", e);
return null;
}
To send custom XML request with kSOAP you need to make your own Transport class.
Or you can send the request manually using DefaultHttpClient (see Using client/server certificates for two way authentication SSL socket on Android), and use kSOAP just for parsing the response.
