Below is the error that logcat springs up. It is unable to parse the <!DOCTYPE...> at the start of any xml document. I tried my program with a page that doesn't have the DOCTYPE tag and it worked successfully. I have used setFeature to enable 'FEATURE_PROCESS_DOCDECL', but it doesn't solve the problem.
The Error: org.xmlpull.v1.XmlPullParserException: Unexpected <! (position:START_DOCUMENT null@1:1 in java.io.InputStreamReader@424355f0)
Excerpt of my code:
URL url = new URL("http://www.google.co.in/webhp?hl=en&tab=ww");
XmlPullParserFactory parser = XmlPullParserFactory.newInstance();
parser.setNamespaceAware(true);
parser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES,true);
parser.setFeature(XmlPullParser.FEATURE_PROCESS_DOCDECL,true);
XmlPullParser xpp = parser.newPullParser();
InputStream ip=url.openConnection().getInputStream();
xpp.setInput(ip, HTTP.UTF_8);
Message msg = mHandler.obtainMessage();
Bundle bundle = new Bundle();
int eventType=xpp.getEventType();
if(eventType==XmlPullParser.START_DOCUMENT){
while(eventType!=XmlPullParser.END_DOCUMENT ){
if(eventType!=XmlPullParser.DOCDECL){
eventType=xpp.nextToken();
}
else if(eventType==XmlPullParser.START_TAG){
if(xpp.getName().equalsIgnoreCase("title")){
bundle.putString("message", xpp.nextText());
msg.setData(bundle);
mHandler.sendMessage(msg);
eventType=xpp.nextToken();
}
}
}
}

I've been having a similar problem. Looks like XmlPullParser doesn't accept the lower case <!doctype html>, instead, it expects the upper-cased version <!DOCTYPE html>. (Related: Uppercase or lowercase doctype?).
This can be found at org.kxml2.io.KXmlParser.java:
/**
* Returns the type of the next token.
*/
private int peekType(boolean inDeclaration) throws IOException, XmlPullParserException {
Beginning at line 1003:
case '!':
switch (buffer[position + 2]) {
case 'D':
return DOCDECL; // <!D
case '[':
return CDSECT; // <![
case '-':
return COMMENT; // <!-
case 'E':
switch (buffer[position + 3]) {
case 'L':
return ELEMENTDECL; // <!EL
case 'N':
return ENTITYDECL; // <!EN
}
break;
case 'A':
return ATTLISTDECL; // <!A
case 'N':
return NOTATIONDECL; // <!N
}
throw new XmlPullParserException("Unexpected <!", this, null);
The workaround I used was to search for that specific line and upper case it.
