Android get attribute value from xml

I am trying to make an app which uses last.fm's web API, sends a query for similar artists and returns all the names of the similar artists. It seems as though I manage to connect and get the xml response properly. However, I cannot extract the value of the name-attribute. I am using artistName = xmlData.getAttributeValue(null, "name"); but all it gives me is null.

String searchString = inputField.getText().toString();
searchString = cleanSearchString(searchString);
if(validateSearchString(searchString)){
nc.setSearchString(searchString);
nc.execute();
}
else{
Toast.makeText(MainActivity.this, INPUTERROR, Toast.LENGTH_SHORT).show();
}
}

String newString = oldSearchString.trim();
newString = newString.replace(" ", "");
return newString;

Here is my Network Communications class:

return receivedData;
}
catch (IOException | XmlPullParserException e){
Log.e("ERROR", e.getMessage(), e);
}
return null;
}
private int tryProcessData(XmlPullParser xmlData){
int artistsFound = 0;

int eventType;
try{

if(xmlData.getName().equals("name")){

}
}
}
}
catch (IOException | XmlPullParserException e){
Log.e("ERROR", e.getMessage(), e);
}
if (artistsFound == 0) {

}
return artistsFound;
}
#Override

if(data != null){

}
else{

}
}
#Override

*/
if (values.length == 1) {
setFoundArtistName(values[0]);
notifyObserver();
}
super.onProgressUpdate(values);
}
private void setFoundArtistName(String newArtistName){
foundArtistName = newArtistName;
}
#Override
public void register(Observer newObserver) {

}
#Override
public void unregister(Observer deleteObserver) {

}
#Override
public void notifyObserver() {
for (Observer o : observers) {
Log.i("my tag.... ", "name = " + foundArtistName);
o.update(foundArtistName);
}
}
}
Here's a screenshot of the xml response in Google Chrome:
The only thing I am interested in extracting at this moment is the the value of the Name-Element.
I am logging the value of foundArtistName (in the method notifyObserver) it gives me A LOT of "my tag.... name = null my tag.... name = null my tag.... name = null etc.."
EDIT: I tried using getText() instead of getAttributeValue(), but it also gives me null.

I found the solution. I was using: artistName = xmlData.getAttributeValue(null, "name");, when I really should've used: artistName = xmlData.nextText();

My list is loading again when I am Pressing Back Button

I am also getting ArrayListIndexOutofBound when I am pressing list item when the orientation is changed.As far my knowledge of android I have written Parcelable code correctly.But I think my issues are with the recycler view setup.I am confused with two declaration of my adapter.Help me

Now I get it after years.I would have simply used.
FLAG_ACTIVITY_CLEAR_TOP - If set, and the activity being launched is already running in the current task, then instead of launching a new instance of that activity, all of the other activities on top of it will be closed and this Intent will be delivered to the (now on top) old activity as a new Intent.

thread and handler call different methods each time

I am working on app which communicate the web server. I want two methods which call by thread and also need two handler method, which used to update UI . 1 thread method and handler method need to fetch data and update UI at start of the activity. 2 thread method and handler method need to post back data on server.
How I implement this.

Doing multiple overlay dynamically in Android and parsed XML latitude and longitude

I am writing an Android application that essentially parses XML data using Fwix's API. The parsing part is working fine. Here's my class, Parser:
package com.magadistudio_student_connect_2011.com;
import java.net.URL;
import java.util.ArrayList;
import org.xmlpull.v1.XmlPullParser;
import android.content.res.XmlResourceParser;
import android.util.Xml;
public class Parser {
//Feed Parsing Method
public ArrayList<Bakery> parse(String url) {
//Array of Episode Objects
ArrayList<Bakery> bakeries = null;
try {
//Encode the URL into a URL Object
URL bakery_feed_url = new URL(url);
//Open a Connection to the feed
XmlPullParser parser = Xml.newPullParser();
try {
parser.setInput(bakery_feed_url.openConnection().getInputStream(), null);
}
finally {
}
int event_type = parser.getEventType();
Bakery current_bakery = null;
boolean done = false;
//Parse the feed, start reading throughout the feed from top to bottom
while (event_type != XmlResourceParser.END_DOCUMENT && !done) {
String tag_name = null;
switch (event_type) {
//Found the start of the feed
case XmlResourceParser.START_DOCUMENT:
bakeries = new ArrayList<Bakery>();
break;
//Found a start tag
case XmlResourceParser.START_TAG:
//apply the data to our Episode object based on the tag name
tag_name = parser.getName();
if (tag_name.equalsIgnoreCase("place")) {
current_bakery = new Bakery();
}
else if(current_bakery != null) {
if (tag_name.equalsIgnoreCase("phone_number")){
current_bakery.setPhone(parser.nextText());
}else if(tag_name.equalsIgnoreCase("city")){
current_bakery.setCity(parser.nextText());
}else if(tag_name.equalsIgnoreCase("province")){
current_bakery.setState(parser.nextText());
}else if(tag_name.equalsIgnoreCase("address")){
current_bakery.setAddress(parser.nextText());
}else if(tag_name.equalsIgnoreCase("lat")){
current_bakery.setLatitude(parser.nextText());
//lat = Integer.parseInt(parser.getAttributeValue(null,"lat"));
}else if(tag_name.equalsIgnoreCase("postal_code")){
current_bakery.setZip(parser.nextText());
}else if(tag_name.equalsIgnoreCase("lng")){
current_bakery.setLongitude(parser.nextText());
//lon = Integer.parseInt(parser.getAttributeValue(null,"lng"));
}else if(tag_name.equalsIgnoreCase("name")){
current_bakery.setPlace_name(parser.nextText());
}
}
break;
//An end tag has been reached
case XmlResourceParser.END_TAG:
tag_name = parser.getName();
//End of an Episode Item
if (tag_name.equalsIgnoreCase("place") && current_bakery != null) {
bakeries.add(current_bakery);
//Reached the end of all bakeries, no more data to collect
}
else if (tag_name.equalsIgnoreCase("places")){
done = true;
}
break;
}
event_type = parser.next();
}
}
catch (Exception e) {
throw new RuntimeException(e);
}
//Return the Episode Array
return bakeries;
}
}
And here is my overlay class, Overlay:

// TODO Auto-generated constructor stub

}
#Override

// Toast.makeText(StudentItemizedOverlay.this, "Hello", Toast.LENGTH_LONG).show();
AlertDialog.Builder dialog = new AlertDialog.Builder(mContext);
dialog.setTitle(item.getTitle());
dialog.setMessage(item.getSnippet());

return true;

I am able to do the XML parsing work fine, but THE PROBLEM is I can't figure out how to get the "lat" and "lng" that I have parsed (and put then into an ArrayList of Strings) and convert them into integers so I can show markers of the respective latitude and longitude location on the map.

OK, so Android's Google Maps native location API uses integers with 6 digits following the decimal point. Therefore, you want to remove the "." from the strings of integers you parsed out. Then, simply do a parseInt to attain the coordinates. With that, drop them into GeoPoints and add them to the overlay. It should be no problem.
Unless I'm missing something here, which is possible.
