I am trying to parse Prefrences Xml file in android but not able to parse that getAttributesCount method is always returning zero

Question

I am trying to parse Preferences Xml file in android but not able to parse that getAttributesCount method

{ k = xmlResourceParser.getAttributeCount(); }

is always returning zero due to which I am not able to parse that file. How to successfully parse that Preferences xml file?

XmlResourceParser xmlResourceParser = Context.getResources().getXml(paramInt); 
String key = null;
String title = null; 
String summary = null; 
String attributeName = null;

try {
    do {
        xmlResourceParser.next();
        i = xmlResourceParser.next();
                       
    } while (i != xmlResourceParser.START_TAG && i != xmlResourceParser.END_DOCUMENT);
} catch (IOException e) {
    e.printStackTrace();
} catch (XmlPullParserException e) {
    e.printStackTrace();
}
    
if (i == 1) {
    return;
}

if (i == 2) {
    k = xmlResourceParser.getAttributeCount();
    Log.d("attributesCount", String.valueOf(k));

    for (int j = 0; j < k; j++) {
        Log.d("attriute name", xmlResourceParser.getAttributeName(j));

        if (xmlResourceParser.getAttributeNamespace(j).equals(ANDROID_SCHEME)) {
            attributeName = xmlResourceParser.getAttributeName(j);

            if (attributeName.equals("key")) {
                key = xmlResourceParser.getAttributeValue(i);
                Log.d("key", key);
            } 

            if (attributeName.equals("title")) {
                title = xmlResourceParser.getAttributeValue(i);
                Log.d("Title inside method", title);
            }

            if (attributeName.equals("summary")) {
                summary = xmlResourceParser.getAttributeValue(i);
            }
        }
    }
}

This is the Xml file that I want to parse. In Android I am using this xml file for user settings.

Please show us your XML. Perhaps there are no attributes?

It's not a good idea to use constants like 1 and 2 to identify the events coming from the pull parser. It means that anyone reading the code has to go to the documentation to find, for example, that 2 means START_TAG.

You've shown some of the processing for the first start tag that you encounter. This code doesn't appear to be in a loop so we can't see what you do after processing the first start tag.

I'm no expert in Android XML file formats, but in the examples I've seen, the first element start tag doesn't have any attributes.
